Crossing and Breeding
No one breed of sheep combines the highest perfection in all those points which give value to this race of animals. One is remarkable for the weight, or early maturity, or excellent quality of its carcass, while it is deficient in quality or quantity of wool; and another, which is valuable for wool, is comparatively deficient in carcass. Some varieties will flourish only under certain conditions of food and climate; while others are much less affected by those conditions, and will subsist under the greatest variations of temperature, and on the most opposite qualities of verdure.
In selecting a breed for any given locality, reference shouldbe had,first, to the feed and climate, or the surrounding natural circumstances; and,second, to the market facilities and demand. Choice should then be made of that breed which, with the advantages possessed, and under all the circumstances, will yield the greatest net value of the marketable product.
Rich lowland herbage, in a climate which allows it to remain green during a large portion of the year, is favorable to the production of large carcasses. If convenient to a market where mutton finds a prompt sale and good prices, then all the conditions are realized which calls for a mutton-producing, as contradistinguished from a wool-yielding, sheep. Under such circumstances, the choice should undoubtedly be made from the improved English varieties—the South-Down, the New Leicester, and the improved Cotswolds or New Oxfordshire sheep. In deciding between these, minor and more specific circumstances must be taken into account. If large numbers are to be kept, the Downs will herd—remain thriving and healthy when kept together in large numbers—much better than the two larger breeds; if the feed, though generally plentiful, is liable to be somewhat short during the droughts of summer, and there is not a certain supply of the most nutritious winter feed, the Downs will better endure occasional short keep; if the market demands a choice and high-flavored mutton, the Downs possess a decided superiority. If, on the other hand, but few are to be kept in the same enclosure, the large breeds will be as healthy as the Downs; if the pastures are somewhat wet or marshy, the former will better subsist on the rank herbage which usually grows in such situations; if they do not afford so fine a quality of mutton, they—particularlythe Leicester—possess an earlier maturity, and give more meat for the amount of food consumed, as well as yield more tallow.
The next point of comparison between the long and the middle woolled families, is the value of their wool. Though not the first or principal object aimed at in the cultivation of any of these breeds, it is, in this country, an important item of incident in determining their relative profitableness. The American Leicester yields about six pounds of long, coarse, combing wool; the Cotswold, somewhat more; but this perhaps counterbalanced by these considerations; the Downs grow three to four pounds of a low quality of carding wool. None of these wools are very salable, at remunerating prices, in the American markets. Both, however, will appreciate in proportion to the increase of manufactures of worsted, flannels, baizes, and the like. The difference in the weight of the fleeces between the breeds is, of itself, a less important consideration than it would at first appear, for reasons which will be given when the connection between the amount of wool produced and the food consumed by the sheep is noticed.
The Cheviots are unquestionably inferior to the breeds above named, except in a capacity to endure a vigorous winter and to subsist on healthy herbage. Used in the natural and artificial circumstances which surround sheep-husbandry in many parts of England—where the fattest and finest quality of mutton is consumed, as almost the only animal food of the laboring classes—the heavy, early-maturing New Leicester, and the still heavier New Oxfordshire sheep seem exactly adapted to the wants of producers and consumers, and are of unrivalled value. To depasture poorersoils, sustain a folding system, and furnish the mutton which supplies the tables of the wealthy, the South-Down meets an equal requirement.
Sufficient attention is by no means paid in many portions of the country to the profit which could be made to result from the cultivation of the sheep. One of the most serious defects in the prevalent husbandry of New England, for example, is the neglect of sheep. Ten times the present number might be easily fed, and they would give in meat, wool, and progeny, more direct profit than any other domestic animal, while the food which they consume would do more towards fertilizing the farms than an equal amount consumed by any other animal. It is notorious that the pastures of that section of the country have seriously deteriorated in fertility and become overrun with worthless weeds and bushes to the exclusion of nutritious grasses.
With sheep—as well as with all other animals—much or prolonged exercise in pursuit of food, or otherwise, is unfavorable to taking on fat. Some seem to forget, in their earnest advocacy of the merits of the different breeds, that the general physical laws which control the development of all the animal tissues as well as functions, are uniform. Better organs will, doubtless, make a better appropriation of animal food; and they may be taught, so to speak, to appropriate it in particular directions: in one breed, more especially to the production of fat; in another, of muck, or lean meat; in yet another, of wool. But, these things being equal, large animals will always require more food than small ones. Animals which are to be carried to a high state of fatness must have plentiful and nutritious food, and they mustexercise but little, in order to prevent the unnecessary combustion in the lungs of that carbon which forms nearly four-fifths of their fat. No art of breeding can counteract these established laws of Nature.
In instituting a comparison between breeds of sheep forwool-growingpurposes, it is undeniable that the question is not, what variety will shear the heaviest or even the most valuable fleece, irrespective of the cost of production. Cost of feed and care, and every other expense, must be deducted, in order to fairly test the profits of an animal. If a large sheep consume twice as much food as a small one, and give but once and a-half as much wool, it is obviously more profitable—other things being equal—to keep two of the smaller sheep. The next question, then, is,—from what breed—with the same expense in other particulars—will the verdure of an acre of land produce the greatest value of wool?
And, first, as to the comparative amount of food consumed by the several breeds. There are no satisfactory experiments which show thatbreed, in itself considered, has any particular influence on the quantity of food consumed. It is found, with all varieties, that the consumption is in proportion to the live weight of the grown animal. Of course, this rule is not invariable in its individual application; but its general soundness has been satisfactorily established. Grown sheep take up between two and a half and three and a third per cent. of their weight, in what is equivalent to dry hay, to keep themselves in store condition.
The consumption of food, then, being proportioned to the weight, it follows that, if one acre is capable of sustaining three Merinos, weighing one hundred pounds each, it willsustain two Leicesters, weighing one hundred and fifty each, and two and two-fifth South-Downs, weighing one hundred and twenty-five each. Merinos of this weight often shear five pounds per fleece, taking flocks through. The herbage of an acre, then, would give fifteen pounds of Merino wool, twelve of Leicester, and but nine and three-fifths of South-Down—estimating the latter as high as four pounds to the fleece. Even the finest and lightest-fleeced sheep known as Merinos average about four pounds to the fleece; so that the feed of an acre would produce as much of the highest quality of wool sold under the name of Merino as it would of New Leicester, and more than it would of South-Down, while the former would be worth from fifty to one hundred per cent. more per pound than either of the latter.
Nor does this indicate all the actual difference, as in the foregoing estimate the live weight of the English breeds is placed low, and that of the Merinos high. The live weight of the five-pound fine-fleeced Merino does not exceed ninety pounds; it ranges, in fact, from eighty to ninety; so that three hundred pounds of live weight—it being understood that all of these live weights refer to ewes in fair ordinary, or what is called store, condition—would give a still greater product of wool to the acre. It is perfectly safe, therefore, to say that the herbage of an acre will uniformly give nearly double the value of Merino that it will of any of the English long or middle wools.
What are the other relative expenses of these breeds? The full-blooded Leicester is in no respect a hardier sheep than the Merino, though some of its crosses are much hardier than the pure-bred sheep: indeed, it is less hardy, under the mostfavorable circumstances. It is more subject to colds; its constitution more readily gives way under disease; the lambs are more liable to perish from exposure to cold, when newly dropped. Under unfavorable circumstances—herded in large flocks, famished for feed, or subjected to long journeys—its capacity to endure, and its ability to rally from sad drawbacks, do not compare, with those of the Merino. The high-bred South-Down, though considerably less hardy than the unimproved parent stock, is still fairly entitled to the appellation of a hardy animal; it is, in fact, about on a pace with the Merino, though it will not bear as hard stocking, without a rapid diminution in size and quality. If the peculiar merits of the animal are to be considered in determining the expenses, as they surely should be, the superior fecundity of the South-Down is a point in its favor, as well for a wool-producing as a mutton sheep. The ewe not only frequently produces twin lambs—as do both the Merino and Leicester—but, unlike the latter, she possesses nursing properties to do justice to them. This advantage, however, is fully counterbalanced by the superior longevity of the Merino. All the English mutton breeds begin to rapidly deteriorate in amount of wool, capacity to fatten, and general vigor, at about five years old; and their early maturity is no offset to this, in an animal kept for wool-growing purposes. This early decay requires earlier and more rapid slaughter than is always economically convenient, or even possible.
It is well, on properly stocked farms, to slaughter or turn off the Merino wether at four or five years old, to make room for the breeding stock; but he will not particularly deteriorate, and he will richly pay the way with his fleece for several yearslonger. Breeding ewes are rarely turned off before eight, and are frequently kept until ten years old, at which period they exhibit no greater marks of age than do the Downs and Leicester at five or six. Instances are known of Merino ewes breeding uniformly until fifteen years old. The improved Cotswold is said to be hardier than the Leicester; but this variety, from their great size, and the consequent amount of food consumed by them, together with the other necessary incidents connected with the breeding of such large animals, is incapacitated from being generally introduced as a wool-growing sheep. All the coarse races have one advantage over the Merino: they are less subject to the visitation of the hoof-ail, and when untreated, this disease spreads with less violence and malignity among them. This has been explained by the fact that their hoofs do not grow long and turn under from the sides, as do those of the Merino, and thus retain dirt and filth in constant contact with the foot.
Taking into account all the circumstances connected with the peculiar management of each race, together with all the incidents, exigencies, and risks of the husbandry of each, it may be confidently asserted that the expenses, other than those of feed, are not smaller per head, or even in the number required to stock an acre, in either of the English breeds above referred to, than in the Merino. Indeed, it may well be doubted whether any of those English breeds, except the South-Down, is on an equality, even, with the Merino, in these respects. For wool-growing purposes, the Merino, then, possesses a marked and decided superiority over the best breeds and families of coarse-woolled sheep. As a mutton sheep, it is inferior to some of those breeds; although not somuch as is popularly supposed. Many persons, who have never tasted Merino mutton, and who have, consequently, an unfavorable impression of it, would, if required to consume the fat and lean together, find it more palatable than the luscious and over-fat New Leicester. The mutton of the cross between the Merino and the Native would certainly be preferred to the Leicester, by anybody but an English laborer, accustomed to the latter, since it is short-grained, tender, and of good flavor. The same is true of the crosses with the English varieties, which will hereafter be treated of more particularly. Grade Merino wethers, half-bloods, for example, are favorites with the drover and butcher, being of good size, extraordinarily heavy for their apparent bulk, by reason of the shortness of their wool, compared with the coarse breeds, making good mutton, tallowing well, and their pelts, from the greater weight of wool on them, commanding an extra price. In speaking of the Merino in this connection, no reference is made to the Saxons, though they are, as is well known, pure-blooded descendants of the former.
Assuming it, then, as settled, that it is to the Merino race that the wool-grower must look for the most profitable sheep, a few considerations are subjoined as to the adaptability of the widely diverse sub-varieties of the race to the wants and circumstances of different portions of the country.
Upon the first introduction of the Saxons, they were sought with avidity by the holders of the fine-woolled flocks of the country, consisting at that time of pure or grade Merinos. Under the decisive encouragement offered both to the wool-grower and the manufacturer by the tariff of 1828, a great impetus was given to the production of the finest wools, andthe Saxon everywhere superseded, or bred out by crossing, the Spanish Merinos. In New York and New England, the latter almost entirely disappeared. In the fine-wool mania which ensued, weight of fleece, constitution, and every thing else, were sacrificed to the quality of the wool. Then came the tariff of 1832, which, as well as that of 1828, gave too much protection to both wool-grower and manufacturer, into whose pursuits agricultural and mercantile speculators madly rushed. Skill without capital, capital without skill, and in some cases, probably, thirst for gain without either, laid hold of these favored avocations. The natural and inevitable result followed. In the financial crisis of 1837, manufacturing, and all other monetary enterprises which had not been conducted with skill and providence, and which were not based on an adequate and vast capital, were involved in a common destruction; and even the most solid and best conducted institutions of the country were shaken by the fury of the explosion. Wool suddenly fell almost fifty per cent. The grower began to be discouraged. The breeder of the delicate Saxons—and they comprised the flocks of nearly all the large wool-growers in the country, at that time—could not obtain for his wool its actual first cost per pound.
When the Saxon growers found that the tariff of 1842 brought them no relief, they began to give up their costly and carefully nursed flocks. The example once set, it became contagious; and then was a period when it seemed as if all the Saxon sheep of the country would be sacrificed to this reaction. Many abandoned wool-growing altogether, at a heavy sacrifice of their fixtures for rearing sheep; others crossed with coarse-woolled breeds; and, rushing from one extreme to theother, some even crossed with the English mutton breeds; or some, with more judgment, went back to the parent Merino stock, but usually selected the heaviest and coarsest-woolled Merinos, and thus materially deteriorated the character of their wool. This period became distinguished by a mania for heavy fleeces. The English crosses were, however, speedily abandoned. The Merino regained his supremacy, lost for nearly a quarter of a century, and again became the popular favorite. It was generally adopted by those who were commencing flocks in the new Western States, and gives its type to the sheep of those regions.
The supply of fine wool, then, proportionably decreased, and that of medium and coarse increased. Wools, for convenience, may be classified as follows:superfine, the choicest quality grown in the United States, and never grown here excepting in comparatively small quantities;fine, good ordinary Saxon;good medium, the highest quality of wool usually known in the market as Merino;medium, ordinary Merino;ordinary, grade Merino and selected South-Down fleeces; and,coarse, the English long-wools, etc. This subdivision is, perhaps, minute enough for all practical purposes here.
It soon became apparent that, to sustain our manufacturing interest—that engaged in the manufacture of fine cloths—the diminution of fine wools should not only be at once arrested, but that the growth of them should be immediately and largely increased. An increased attention was accordingly bestowed upon this branch of industry, and sections of the country which had previously held aloof from wool-growing, embarked in that calling with commendable enterprise.
The climate north of forty-one degrees, or, beyond alldispute, north of forty-two degrees, is too severe for any variety of sheep commonly known, which bear either superfine or fine wools. In fact, the only such variety in any thing like general use is the Saxon; and this, as has been remarked, is a delicate sheep, entirely incapable of safely withstanding our northern winters, without good shelter, good and regularly-administered food, and careful and skilful management in all other particulars. When the season is a little more than usually back-hand, so that grass does not start prior to the lambing season, it is difficult to raise the lambs of the mature ewes; the young ewes will, in many instances, disown their lambs, or, if they own them, not have a drop of milk for them; and if, under such circumstances, as often happens, a northeast or a northwest storm comes driving down, bearing snow or sleet in its wings, or there is a sudden depression of the temperature from any cause, no care will save multitudes of lambs from perishing. If the time of having the lambs dropped is deferred, for the purpose of escaping these evils, they will not attain size and strength sufficient to enable them to pass safely through their first winter. North of the latitude last named, it is necessary, as a general rule, that they be dropped in the first half of May, to give them this requisite size and strength; and occasional cold storms come, nearly every season, up to that period, and, not unfrequently, up to the first of June.
These considerations have had their weight even with the few large sheep-holders in that section, whose farms and buildings have been arranged with exclusive reference to the rearing of these sheep; many of whom have adopted a Merino cross. With the ordinary farmers—the small sheep-owners, who, in the aggregate, grow by far the largest portion of thenorthern wools—the Saxon sheep is, for these reasons, in marked disrepute. They have not the necessary fixtures for their winter protection, and are unwilling to bestow the necessary amount of care on them. Besides, mutton and wool being about an equal consideration with this class, they want larger and earlier maturing breeds. Above all, they want a strong, hardy sheep, which demands no more care than their cattle. The strong, compact, medium-woolled Merino, or, more generally, its crosses with coarse varieties, producing the wool classed as ordinary, is the common favorite. In the Northwest, this is especially the case, where the climate is still worse for delicate sheep.
At the South, on the contrary—where these disadvantages do not exist to so great an extent, certainly—wool varying from good medium upward are more profitable staples for cultivation than the lower classes; and in that section a high degree of fineness in fleece has been sought in breeding the Merino—the four-pound fine-fleeced Merino having received marked attention. This is a far more profitable animal than the Saxon, other things being equal—which is not the case, since the former is every way a hardier animal and a better nurse; and, although about twenty pounds heavier, and therefore consuming more feed, this additional expense is more than counterbalanced by the additional care and risk attending the husbandry of the Saxon.
For breeding purposes, the shape and general appearance of the Merino should be as follows:—The head should be well carried up, and in the ewe hornless. It would be better,on many accounts, to have the ram also hornless, but, as horns are usually characteristic of the Merino ram, many prefer to see them. The face should be rather short, broad between the eyes, the nose pointed, and, in the ewe, fine and free from wrinkles. The eye should be bright, moderately prominent, and gentle in its expression. The neck should be straight—not curving downward—short, round, and stout—particularly so at its junction with the shoulder, forward of the upper point of which it should not sink below the level of the back. The points of the shoulder should not rise to any perceptible extent above the level of the back. The back, to the hips, should be straight; the crops—that portion of the body immediately back of the shoulder-blades—full; the ribs well arched; the body large and capacious; the flank well let down; the hind-quarters full and round—the flesh meeting well down between the thighs, or in the “twists.” The bosom should be broad and full; the legs short, well apart, and perpendicular—that is, not drawn under the body toward each other when the sheep is standing. Viewed as a whole, the Merino should present the appearance of a low, stout, plump, and—though differing essentially from the English mutton-sheep model—a highly symmetrical sheep.
The skin is an important point. It should be loose, singularly mellow, and of a rich, delicate pink color. A colorless skin, or one of a tawny, approaching to a butternut, hue, indicates bad breeding. On the subject of wrinkles, there is a difference of opinion. As they are rather characteristic of the Merino—like the black color in a Berkshire hog, or the absence of all color in Durham cattle—these wrinkles have been more regarded, by novices, than those points which giveactual value to the animal; and shrewd breeders have not been slow to act upon this hint. Many have contended that more wool can be obtained from a wrinkled skin; and this view of the case has led both the Spanish and French breeders to cultivate them largely—the latter, to a monstrosity. An exceedingly wrinkled neck, however, adds but little to the weight of the fleece—not enough, in fact, to compensate for the deformity, and the great impediment thus placed in the way of the shearer. A smoothly drawn skin, and the absence of all dead lap, would not, on the other hand, perhaps be desirable.
The wool should densely cover the whole body, where it can possibly grow—from a point between and a little below the eyes, and well up on the cheeks, to the knees and hocks. Short wool may show, particularly in young animals, on the legs, even below the knees and hocks; but long wool covering the legs, and on the nose, below the eyes, is unsightly, without value; while on the face it frequently impedes the sight of the animal, causing it to be in a state of perpetual alarm, and disqualifying it to escape real danger. Neither is this useless wool the slightest indication of a heavy fleece—contrary to what seems to be thought by some. It is very often seen in Saxons shearing scarcely two pounds of wool, and on the very lightest fleeced Merinos.
The amount of gum which the wool should exhibit is another mooted point. Merino wool should be yolky, or oily, prior to washing—though not to the extreme extent, occasionally witnessed, of giving it the appearance of being saturated with grease. The extreme tips may exhibit a sufficient trace of gum to give the fleece a darkish cast,particularly in the ram; but a black, pitchy gum, resembling half-hardened tar, extending an eighth or a quarter of an inch into the fleece, and which cannot be removed by ordinary washing, is decidedly objectionable. There is a white or yellowish concrete gum, not removable by common washing, which appears in the interior of some fleeces, and is equally objectionable.
The weight of fleece remaining the same, medium length of staple, with compactness, is preferable to long, open wool, since it constitutes a better safeguard from inclemencies of weather, and better protects the animal from the bad effects of cold and drenching rains in spring and fall. The wool should be, as nearly as possible, of even length and thickness over the entire body. Shortness on the flank, and shortness or thickness on the belly, are serious defects.
Evenness of fleece is a point of the first importance. Many sheep exhibit good wool on the shoulder and side, while it is far coarser and even hairy on the thighs, dew-lap, etc. Rams of this stamp should not be bred from by any one aiming to establish a superior fine-woolled flock; and all such ewes should gradually be excluded from those selected for breeding.
The style of the wool is a point of as much importance as mere fineness. Some very fine wool is stiff, and the fibres almost straight, like hair. It has a dry, cottony look; and is a poor, unsalable article, however fine the fibre. Softness of wool—a delicate, silky, highly elastic feel between the fingers or on the lips, is the first thing to be regarded. This is usually an index, or inseparable attendant, of the other good qualities; so much so, indeed, that an experienced judge can decide, with little difficulty, between the quality of two fleeces,in the dark. Wool should be finely serrated, or crimped from one extremity to the other: that is, it should present a regular series of minute curves; and, generally, the greater the number of these curves in a given length, the higher the quality of the wool in all other particulars. The wool should open on the back of the sheep in connected masses, instead of breaking up into little round spiral ringlets of the size of a pipe-stem, which indicate thinness of fleece; and when the wool is pressed open each way with the hands, it should be close enough to conceal all but a delicate rose-colored line of skin. The interior of the wool should be a pure, glittering white, with a lustre and liveliness of appearance not surpassed in the best silk.
The points in the form of the Merino which the breeder is called upon particularly to avoid are, a long, thin head, narrow between the eyes; a thin, long neck, arching downward before the shoulders; narrow loins; flat ribs; steep, narrow hind-quarters; long legs; thighs scarcely meeting at all; and legs drawn far under the body at the least approach of cold. All these points were, separately or conjointly, illustrated in many of the Saxon flocks which have been swept from the country. Sufficient attention has already been paid to the points to be avoided in the fleece.
The first great starting-point, among pure-blood animals, is, that “like will beget like.” If the sire and ewe are perfect in any given points, the offspring will generally be; if either is defective, the offspring—subject to a law which will possibly be noticed—will be half-way between the two; if both aredefective in the same points, the progeny will be more so than either of its parents—it will inherit the amount of defect in both parents added together. There are exceedingly few perfect animals. Breeding, therefore, is a system of counterbalancing—breeding out—in the offspring, the defects of one parent, by the marked excellence of the other parent, in the same points. The highest blood confers on the parent possessing it the greatest power of stamping its own characteristics on its progeny; but, blood being the same, the male sheep possesses this power in a greater degree than the female. We may, therefore, in the beginning, breed from ewes possessing any defects short of cardinal ones, without impropriety, provided we possess the proper ram for that purpose; but, where a high standard of quality is aimed at, all ewes possessing even considerable defects should gradually be thrown out from breeding. Every year should add to the vigor of the selection.
But, from the beginning—and at the beginning, more than at any other time—the greatest care should be evinced in the selection of the ram. If he has a defect, that defect is to be inherited by the whole future flock; if it is a material one—as, for example, a hollow back, bad cross, or thin fleece, or a highly uneven fleece—the flock will be one of low quality and little value. If, on the other hand, he is perfect, the defects in the female will be lessened, and gradually bred out. It being, however, difficult to find perfect rams, those should be taken which have the fewest and lightest defects, and none of these material, like those just enumerated. These defects are to be met and counterbalanced by the decided excellence—sometimes, indeed, running into a fault—of the ewe, in thesame points. If the ram, then, is a little too long-legged, the shortest-legged ewes should be selected for him; if gummy, the dryest-woolled; if his fleece is a trifle below the proper standard of fineness—but he has been retained, as often happens, for weight of fleece and general excellence—he is to be put to the finest and lightest-fleeced ewes, and so on. With a selection of rams, this system of counterbalancing would require but little skill, if each parent possessed only a single fault. If the ewe be a trifle too thin-fleeced, and good in all other particulars, it would require no nice judgment to decide that she should be bred to an uncommonly thick-fleeced ram. But most animals possess, to a greater or less degree, several defects. To select so that every one of these in the dam shall meet its opposite in the male, and the contrary, requires not only plentiful materials from which to select, but the keenest discrimination.
After the breeder has successfully established his flock, and given them an excellent character, he soon encounters a serious evil. He must “breed in-and-in,” as it is called—that is, interbreed between animals more or less nearly related in blood—or he must seek rams from other flocks, at the risk of losing or changing the distinctive character of his flock, hitherto so carefully sought, and built up with so much painstaking. The opponents of in-and-in breeding contend that it renders diseases and all other defects hereditary, and that it tends to decrease of size, debility, and a general breaking up of the constitution. Its defenders, on the other hand, insist that, if the parents are perfectly healthy, this mode does not, of itself, tend to any diminution of healthfulness in the offspring; and they likewise claim—which must be conceded—that it enables the skilful breeder much more rapidly to bring his flock to a particular standard or model, and to keep it there much more easily—unless it be true that, in course of time, they will dwindle and grow feeble.

So far as the effect on the constitution is concerned, both positions may be, to a certain extent, true. But it is, perhaps, difficult always to decide with certainty when an animal is not only free from disease, but from all tendency or predisposition towards it. A brother or sister may be apparently healthy—may be actually so—but may still possess a peculiarity of individual conformation which, under certain circumstances, will manifest itself. If these circumstances do not chance to occur, they may live until old age, apparently possessing a robust constitution. If tried together, their offspring—by a rule already laid down—will possess this individual tendency in a double degree. If the ram be interbred with sisters, half-sisters, daughters, granddaughters, etc., for several generations, the predisposition toward a particular disease—in the first place slight, now strong, and constantly growing stronger—will pervade, and becomeradically incorporated into, the constitution of the whole flock. The first time the requisite exciting causes are brought to bear, the disease breaks out, and, under such circumstances, with peculiar severity and malignancy. If it be of a fatal character, the flock is rapidly swept away; if not, it becomes chronic, or periodical at frequently recurring intervals. The same remarks apply, in part, to those defects of the outward form which do not at first, from their slightness, attract the notice of the ordinary breeder. They are rapidly increased until, almost before thought of by the owner, they destroy the value of the sheep. That such are the common effects of in-and-in breeding, with such skill as it is commonly conducted, all know who have given attention to the subject; and for these reasons the system is regarded with decided disapprobation and repugnance by nine out of ten of the best practical farmers.
The sheep-breeder can, however, avoid the effects of in-and-in breeding, and at the same time preserve the character of his flock, by seeking rams of the same breed, possessing, as nearly as possible,the characteristics which he wishes to preserve in his own flock. If this rule is neglected—if he draws indiscriminately from all the different varieties or families of a breed—some large, and some small—some long-woolled, and some short-woolled—some medium, and some superfine in quality—some tall, and some squatty—some crusted over with black gum, and some entirely free from it—breeding will become a mere matter of hap-hazard, and no certain or uniform results can be expected. So many varieties cannot be fused into one for a number of generations—as is evidenced by the want of uniformity in the Rambouillet flock,which was commenced by a promiscuous admixture of all the Spanish families; and it not merely happens, as between certain classes of Saxons, that particular families can never be successfully amalgamated.
If, however, the breeder has reached no satisfactory standard—if his sheep are deficient in the requisites which he desires—he is still to adhere to the breed—provided the desired requisites are characteristic of the breed he possesses—and select better animals to improve his own inferior ones. If he has, for instance, an inferior flock of South-Downs, and wishes to obtain the qualities of the best Down dams, he should seek for the best rams of that breed. But if he wishes to obtain qualitiesnot characteristic of the breed he possesses, he must cross with a breed which does possess them. If the possessor of South-Downs wishes to convert them into a fine-woolled sheep similar to the Merino, he should cross his flock steadily with Merino rams—constantly increasing the amount of Merino, and diminishing the amount of South-Down blood. To effect the same result, he would take the same course with the common sheep of the country, or with any other coarse race.
There are those, who, forgetting that some of the finest varieties now in existence, of several kinds of domestic animals, are the result of crosses—bitterly inveigh against the practice of crossing, under any and all circumstances. It is, it must be admitted, an unqualified absurdity, as frequently conducted—as, for example, an attempt to unite the fleece of a Merino and the carcass of a Leicester, by crosses between those breeds; but, under the limitations already laid down, and with the objects specified as legitimate ones, thisobjection to crossing savors of the most profound prejudice, or the most unblushing quackery. It is neither convenient, nor within the means of every man wishing to start a flock of sheep, to commence exclusively with full-bloods. With a few to breed rams from, and to begin a full-blood stock, the breeder will find it his best policy to purchase the best common sheep of his country, and gradually grade them up with Merino rams. In selecting the ewes, good shape, fair size, and a robust constitution, are the main points—the little difference in the quality of the common sheep’s wool being of no consequence. For their wool, they are to look to the Merino; but good form and constitution they can and ought to possess, so as not to entail deep-rooted and entirely unnecessary evils on their progeny.
Satisfactory results have followed crossing a Down ram—small, compact, exceedingly beautiful, fine and even fleeced—with large-sized Merino ewes. The half-blood ewes were then bred to a Merino ram, and also their female progeny, and so on. The South-Downs, from a disposition to take on fat, manifested themselves, to a perceptible extent, in every generation, and the wool of many of the sheep in the third generation—seven-eighths blood Merino, and one-eighth blood Down—was very even, and equal to medium, and some of them to good medium Merino. Their fleeces were lighter than the full-blood Merinos, but increased in weight with each succeeding cross back toward the latter. The mutton of the first, and even of the second cross was of a beautiful flavor, and retained, to the last, some of the superiority of South-Down mutton.
Results are also noted of breeding Leicester ewes—takingone cross of the blood, as in the preceding case—toward the Merino. The mongrels, to the second generation—beyond which they were not bred—were about midway between the parent stock in size—with wool shorter, but far more fine and compact than the Leicester—their fleeces about the same weight, five pounds—and, altogether, they were a showy and profitable sheep, and well calculated to please the mass of farmers. Their fleeces, however, lacked evenness, their thighs remaining disproportionately coarser and heavy.
A difference of opinion exists in relation to the number of crosses necessary before it is proper to breed from a mongrel ram. Some high authorities assert that it does not admit of the slightest doubt that a Merino, in the fourth generation, from even the worst-woolled ones, is in every respect equal to the stock of the sire—that no difference need to be made in the choice of a ram, whether he is a full-blood, or a fifteen-sixteenths—and that, however coarse the fleece of the parent ewe may have been, the progeny in the fourth generation will not show it.
Others, however—while admitting that the only value of blood or pedigree, in breeding, is to insure the hereditary transmission of the properties of the parent to the offspring, and that, as soon as a mongrel reaches the point where he stamps his characteristics on the progeny, with the same certainty that a full-blood does, he is equally valuable, provided he is, individually, as perfect an animal—contend that this cannot be depended upon, with any certainty, in rams of the fourth Merino cross. They assert that the offspring of such crosses invariably lack the style and perfection of thorough-bred flocks. The sixth, seventh, or eighth cross might be generally,and the last, perhaps, almost invariably, as good as pure-blood rams; yet pure blood is a fixed standard, and were every breeder to think himself at liberty to depart from it in his rams, each one more or less, according to his judgment or caprice, the whole blood of the country would become adulterated. No man, assuredly, can be authorized to sell a ram of any cross, whether the tenth, or even the twentieth, as a full-blood.
It is of the utmost importance for thosecommencingflocks, either of full-bloods, or by crossing, to select the choicest rams. A grown ram may, by methods which will hereafter be described, be made to serve from one hundred to one hundred and fifty ewes in a season. A good Merino ram will, moderately speaking, add more than a pound of wool to the fleece of the dam, or every lamb got by it, from a common-woolled ewe—that is, if the ewe at three years old sheared three pounds of wool, the lamb at the same age will shear four. This would give one hundred or one hundred and fifty pounds of wool for the use of a ram for a single season; and every lamb subsequently got by him adds a pound to this amount. Many a ram gets, during his life, eight hundred or one thousand lambs. Nor is the extra amount of wool all. He gets from eight hundred to one thousand half-blooded sheep, worth double their dams, and ready to be made the basis of another and higher stride in improvement. A good ram, then, is as important and, it may be, quite as valuable an animal as a good farm-horse stallion. When the number of a ram’s progeny are taken into consideration, and when it is seen over what an immense extent, even in his own direct offspring, his good or bad qualities are to be perpetuated, the folly of thateconomy which would select an inferior animal is sufficiently obvious.
It will be found the best economy in starting a flock, where the proper flocks from which to draw rams are not convenient, to purchase several of the same breed, of course, butof different strains of blood. Thus ram No. 2 can be put on the offspring of No. 1, and the reverse; No. 3 can be put on the offspring of both, and both upon the offspring of No. 3. The changes which can be rung on three distinct strains of blood, without in-and-in breeding close enough to be attended with any considerable danger, are innumerable.
The brother and sister, it will be born in mind, are of the same blood; the father and daughter, half; the father and granddaughter, one-fourth; the father and great-granddaughter, one-eighth; and so on. Breeding between animals possessing one-eighth of the same blood, would not be considered very close breeding; and it is not unusual, in rugged, well-formed families, to breed between those possessing one-fourth of the same blood.
If, however, these rams of different strains are brought promiscuously, without reference to similarity of characteristics, there may, and probably will, be difference between them; and it might require time and skill to give a flock descended from them a proper uniformity of character. Those who breed rams for sale should be prepared to furnish different strains of blood, with the necessary individual and family uniformity.
Some few suggestions upon the general principles to be observed in breeding may not be superfluous here, referringthe reader, who is disposed to investigate this subject in detail, to its full discussion in the author’s treatise upon “Cattle and their Diseases.”
As illustrative of the importance ofbreeding only from the best, taking care to avoid structural defects, and especially to secure freedom fromhereditary diseases, since both defects and diseases appear to be more easily transmissible than desirable qualities, it may be remarked that scrofula is not uncommon among sheep, and presents itself in various forms. Sometimes it is connected with consumption; sometimes it affects the viscera of the abdomen, and particularly the mesenteric glands, in a manner similar to consumption in the lungs. The scrofulous taint has been known to be so strong as to affect the fœtus, and lambs have occasionally been dropped with it; but much oftener they show it at an early age, and any affected in this way are liable to fall an easy prey to any ordinary or prevalent disease, which develops in such with unusual severity. Sheep are also liable to several diseases of the brain, and of the respiratory and digestive organs. Epilepsy, or “fits,” and rheumatism sometimes occur.
The breeder’s aim should be to grasp andrender permanent, and increase so far as practicable,every variation for the better, and to reject for breeding purposes such as show a downward tendency. A remarkable instance of the success which has often attended the well-directed efforts of intelligent breeders, is furnished in the new Mauchamp-Merino sheep, which originated in a single animal—a product of the law of variation—and which, by skilful breeding and selection, has become an established breed of a peculiar type, and possessing valuable properties. Samples of the wool of these sheep were shownat the great exhibition in London, in 1851, as well as at the subsequent great agricultural exhibition at Paris, and attracted much attention.
This breed was originated by Mons. J. L. Graux. In 1828, a Merino ewe produced a peculiar ram lamb, having a different shape from the ordinary Merino, and possessing wool singularly long, straight, and silky. Two years afterward, Mr. Graux obtained by this ram one ram and one ewe, having the silky character of wool. Among the produce of the ensuing year were four rams and one ewe with similar fleeces; and in 1833, there were rams enough of the new sort to serve the whole flock of ewes. In each subsequent year, the lambs were of two kinds; one possessing the curled, elastic wool of the old Merinos, only a little longer and finer, and the other like the new breed. At last, the skilful breeder obtained a flock containing the fine, silky fleece with a smaller breed, broader flanks, and more capacious chest; and several flocks being crossed with the Mauchamp variety, the Mauchamp-Merino breed is the result.
The pure Mauchamp wool is remarkable for its qualities as a combing-wool, owing to the strength, as well as the length and fineness of the fibre. It is found of great value by the manufacturers of Cashmere shawls, and similar goods, being second only to the true Cashmere fleece, in the fine, flexible delicacy of the fibre; and when in combination with Cashmere wool, imparting strength and consistency. The quantity of this wool has since become as great as that from ordinary Merinos, or greater, while its quality commands twenty-five per cent. higher price in the French market. Breeders,certainly, cannot watch too closely any accidental peculiarity of conformation or characteristic in their flocks.
The apparent influence of the malefirst having fruitful intercourse with a female,upon her subsequent offspring by other males, has been noticed by various writers. The following well-authenticated instances are in point:
A small flock of ewes, belonging to Dr. W. Wells, in the island of Granada, was served by a ram procured for the purpose. The ewes were all white and woolly; the ram was quite different, being of a chocolate color, and hairy like a goat. The progeny were, of course, crosses, but bore a strong resemblance to the male parent. The next season, Dr. Wells obtained a ram of precisely the same breed as the ewes; but the progeny showed distinct marks of resemblance to the former ram, in color and covering. The same thing occurred on neighboring estates, under like circumstances.
Six very superior pure-bred black-faced horned ewes, belonging to Mr. H. Shaw, of Leochel, Cushnie, were served by a white-faced hornless Leicester ram. The lambs were crosses. The next year they were served by a ram of exactly the same breed as the ewes themselves, and their lambs were, without an exception, hornless and brownish in the face, instead of being black and horned. The third year they were again served by a superior ram of their own breed; and again the lambs were mongrels, but showed less of the Leicester characteristics than before; and Mr. Shaw at last parted from these fine ewes without obtaining a single pure-bred lamb.
To account for this result—seemingly regarded by most physiologists as inexplicable—Mr. James McGillivray, V. S., of Huntley, has offered an explanation, which has received thesanction of a number of competent writers. His theory is, that when a pure animal of any breed has been pregnant by an animal of a different breed, such pregnant animalis a cross ever after, the purity of her blood being lost, in consequence of her connection with the foreign animal, and herself becoming a cross forever, incapable of producing a pure calf of any breed.
To cross,merely for the sake of crossing, to do so without that care and vigilance which are highly essential, is a practice which cannot be too much condemned, being, in fact, a national evil, if pushed to such an extent as to do away with a useful breed of animals, and establish a generation of mongrels in their place—a result which has followed in numerous instances amongst every breed of animals.
The principal use of crossing is to raise animals for the butcher. The male, being generally an animal of a superior breed, and of a vigorous nature, almost invariably stamps his external form, size, and muscular development on the offspring, which thus bear a strong resemblance to him; while their internal nature, derived from the dam, well adapts them to the locality, as well as to the treatment to which their dams have been accustomed.
With sheep, where the peculiarities of the soil, as regards the goodness of feed, and exposure to the severities of the weather, often prevent the introduction of an improved breed, the value of using a new and superior ram is often very considerable; and the weight of mutton is thereby materially increased, without its quality being impaired, while earlier maturity is at the same time obtained. It involves, however, more systematic attention than most farmers usually like to bestow, for it is necessary to employ a different ram for eachpurpose; that is, a native ram, for a portion of the ewes to keep up the purity of the breed, and a foreign ram, to raise the improved cross-bred animals for felting, either as lambs or sheep. This plan is adopted by many breeders of Leicester sheep, who thus employ South-Down rams to improve the quality of the mutton.
One inconvenience attending this plan is the necessity of fattening the maiden ewes as well as the wethers. They may, however, be disposed of as fat lambs, or the practice of spaying (fully explained in “Cattle and their Diseases”) might be adopted, so as to increase the felting disposition of the animal. Crossing, therefore, should be adopted with the greatest caution and skill, where the object is to improve the breed of animals. It should never be practised carelessly or capriciously, but it may be advantageously pursued, with a view to raising superior and profitable animals for the butcher. For the latter purpose, it is generally advisable to use males of a larger breed, provided they possess a disposition to fatten; yet, in such cases, it is of importance that thepelvisof the female should be wide and capacious, so that no injury may arise in lambing, in consequence of the increased size of the heads of the lambs. The shape of the ram’s head should be studied for the same reason.
In crossing, however, for the purpose of establishing a new breed, the size of the male must give way to other more important considerations; although it will still be desirable to use a large female of the breed which is sought to be improved. Thus, the South-Downs have vastly improved the larger Hampshires, and the Leicester, the huge Lincolns and the Cotswolds.
Merino rams are frequently used from the first to the tenth year, and even longer. The lambs of very old rams are commonly supposed not to be as those of middle-aged ones; though where rams have not been overtasked, and have been properly fed, little if any difference is discoverable in their progeny by reason of their sire’s age. A ram lamb should not be used, as it retards his growth, injures his form, and, in many instances, permanently impairs his vigor and courage. A yearling may run with thirty ewes, a two-year-old with from forty to fifty, and a three-year-old with from fifty to sixty; while some very powerful, mature rams will serve seventy or eighty. Fifty, however, is enough, where theyrun withthe ewes. It is well settled that an impoverished and overtasked animal does not transmit his individual properties so decidedly to his offspring as does one in full vigor.
Rams, of course, are not to be selected for ewes by mere chance, but according as their qualities may improve those of the ewes. It may not be superfluous, though seemingly a repetition, to state that a good ewe flock should exhibit these characteristics:strong bone, supporting a roomy frame, affording space for a large development of flesh;abundance of wool of a good quality, keeping the ewes warm in inclement weather, and insuring profit to the breeder;a disposition to fatten early, enabling the breeder readily to get rid of his sheep selected for the butcher; anda prolific tendency, increasing the flock rapidly, and being also a source of profit. Every one of these properties is advantageous in itself; but when all are combined in the same individuals of a flock, that flock is in a high stateof perfection. In selecting rams, it should be observed whether or not they possess one or more of those qualities in which the ewes may be deficient, in which case their union with the ewes will produce in the progeny a higher degree of perfection than is to be found in the ewes themselves, and such a result will improve the state of the future ewe-flock; but, on the contrary, if the ewes are superior in all points to the rams, then, of course, the use of such will only serve to deteriorate the future ewe-flock.
Several rams running in the same flock excite each other to an unnatural and unnecessary activity, besides injuring each other by constant blows. It is, in every point of view, bad husbandry, where it can be avoided, and, as customarily managed, is destructive to every thing like careful and judicious breeding. The nice adaptation which the male should possess to the female is out of the question where half a dozen or more rams are running promiscuously with two or three hundred ewes.
Before the rams are let out, the breeding ewes should all be brought together in one yard; the form of each noted, together with the length, thickness, quality and style of her wool—ascertained by opening the wool on the shoulder, thigh, and belly. When every point is thus determined, that ram should be selected which, on the whole, is best calculated to perpetuate the excellencies of each, both of fleece and carcass, and to best counterbalance defects in the mutual offspring. Every ewe, when turned in with the ram, should be given a distinct mark, which will continue visible until the next shearing. For this purpose, nothing is better than Venetian red and hog’s lard, well incorporated, and marked on with a cob. The ewes foreach ram require a differently shaped mark, and the mark should also be made on the ram, as noted in the sheep-book. Thus it can be determined at a glance by what ram the ewe was tapped, any time before the next shearing. The ewes selected for each ram are placed in different enclosures, and the chosen ram placed with them. Rams require but little preparation on being put among ewes. If their skin is red in the flanks when the sheep are turned up, they are ready for the ewes, for the natural desire is then upon them. Most of the ewes will be served during the second week the ram is among them, and in the third, all. It is better, however, not to withdraw the rams until the expiration of four weeks, when the flocks can be doubled, or otherwise re-arranged for winter, as may be necessary. The trouble thus taken is, in reality, slight—nothing, indeed, when the beneficial results are considered. With two assistants, several hundred ewes may be properly classified and divided in a single day.
Where choice rams are scarce, so that it is desirable to make the services of one go a great way, or where it is impossible to have separate enclosures—as on farms where there are a great number of breeding ewes, or where the shepherd system is adopted, to the exclusion of fences—resort may be had to another method. A hut should be built, containing as many apartments as the ram is desired to be used, with an alley between them, each apartment to be furnished with a feeding-box and trough in one corner, and gates or bars opening from each into the alley, and at each end of the alley. Adjoining these apartments, a yard should be inclosed, of size just sufficient to hold the flock of breeding ewes.
A couple of strong rams, of any quality, for about everyhundred ewes, are then aproned, their briskets rubbed with Venetian red and hog’s lard, and let loose among the ewes.Aproningis performed by sewing a belt of coarse sacking, broad enough to extend from the fore to the hind legs, loosely but strongly around the body. To prevent its slipping forward or back, straps are carried round the breast and back of the breech. It should be madeperfectly secure, or all the labor of this method of coupling will be far worse than thrown away. The pigment on the brisket should be renewed every two or three days; and it will be necessary to change the “teasers”—as these aproned rams are called—about once a week, as they do not long retain their courage under such unnatural circumstances. Twice a day the ewes are brought into the yard in front of the hut. Those marked on their rumps by the teasers are taken into the alley. Each is admittedonceto the ram for which she is marked, and then goes outat the opposite end of the alleyfrom which they entered, into a field separate from that containing the flock from which she was taken. A powerful and vigorous ram, from three to seven years old, and properly fed, can thus be made to serve from one hundred and fifty to even two hundred ewes, with no greater injury than from running loose with fifty or sixty. The labor here required is likewise more apparent than real, when the operation is conducted in a systematic manner.
Rams will do better, accomplish more, and last two or three years longer, if daily fed with grain, when on service, and it is better to continue it. In all cases, they should, after serving, be put on good pasture, as they will have lost a good deal of condition, being indisposed to settle during the tapping season.A ram should receive the equivalent of from half a pint to a pint of oats daily, when worked hard. They are much more conveniently fed when kept in huts. If suffered to run at large, they should be so thoroughly tamed that they will eat from a measure held by the shepherd. Careful breeders thus train their stock-rams, from the time they are lambs. It is very convenient, also, to have them halter-broke, so that they can be led about without dragging or lifting them. An iron ring attached to one of the horns, near the point, to which a cord can be fastened for leading, confining, etc., is very useful and convenient. If rams are wild, it is a matter of considerable difficulty to feed them separately, and it can only be effected by yarding the flock and catching them out. Some breeders, in addition to extra feeding, take the rams out of the flocks each night, shutting them up in a barn or stable by themselves. To this practice there is no objection, and it greatly saves their strength.
Rams should not be suffered to run with the ewes over a month, at least in the Northern States. It is much better that a ewe go dry than that she have a lamb later than the first of June. Besides, after the rutting season is over, the rams grow cross, frequently striking the pregnant ewes dangerous blows with their heavy horns, at the racks and troughs.
It is reasonably enough conjectured, that if procreation and the first period of gestation take place in cold weather, the fœtus will be fitted for the climate which rules during the early stages of its existence. If this be so—and it is certainly in accordance with the laws of Nature—fine-woolled sheep are most likely to maintain their excellence by deferring the connection of the male till the commencement of cold weather;and, in the Northern States, this is done about the first of December, thus bringing the yeaning time in the last of April, or the first of May, when the early grass affords a large supply and good quality of food.
