It must be remembered that sheep are not to be allowed to get thin during the winter, with the idea that their condition can at any time be readily raised by better feed, as with the horse or ox. It is always difficult, and, unless properly managed, expensive and hazardous, to attempt to raise the condition of a poor flock in the winter, especially if they have reached that point where they manifest weakness. If the feeding of a liberal allowance of grain be suddenly commenced, fatal diarrhœa will often supervene. All extra feeding, therefore, must be begun very gradually; and it does not appear, in any case, to produce proportionable results.
Roots, such as ruta-bagas, Irish potatoes, and the like, make a good substitute for grain, or as extra feed for grown sheep. The ruta-baga is preferable to the potato in its equivalents of nutriment. No root, however, is as good for lambs and yearlings as an equivalent of grain. Sheep may be taught to eat nearly all the cultivated roots. This is done by withholding salt from them, and then feeding the chopped roots a few times, rubbed with just sufficient salt to induce them to eat the root to obtain it; but not enough to satisfy their appetite for salt before they have acquired a taste for the roots.
It is customary with some farmers to cut down, from time to time in the winter, and draw into the sheep-yards, young trees of the hemlock, whose foliage is greedily eaten by the sheep, after being confined for some time to dry feed. This browse is commonly used, like tar, for some supposed medicinal virtues. It is pronounced “healthy” for sheep. Much the same remarks might be made about this as have been already made concerning tar. No tonics and stimulants are needed for a healthy animal. If the foliage of the hemlock were constantly accessible to them, there would be no possible objection to their eating it, since their instincts, in that case, would teach them whether, and in what quantities, to devour it; but when entirely confined to dry feed for a protracted period, sheep will consume injurious and even poisonous succulents, and of the most wholesome ones, hurtful quantities. As a mere laxative, an occasional feed of hemlock may be beneficial; though, in this point of view, a day’s run at grass, in a thaw, or a feed of roots, would produce the same result. In a climate where grass is procurable most of the time, browse for medicinal purposes is entirely unnecessary.
Sheep undoubtedly require salt in winter. Some salt their hay when it is stored in the barn or stack. This is objectionable, since the appetite of the sheep is much the safest guide in the premises. It may be left accessible to them in the salt-box, as in summer; or an occasional feed of grined hay or straw may be given them in warm, thawing weather, when their appetite is poor. This last is an excellent plan, and serves a double purpose. With a wisp of straw, sprinkle a thin layer of straw with brine, then another layer of straw, and another sprinkling, and so on. Let this lie until the next day, for the brine to be absorbed by the straw, and then feed it to all the grazing animals on the farm which need salting.
Water is indispensable, unless sheep have access to succulent food, or clean snow. Constant access to a brook or spring is best; but, in default of this, they should be watered at least once a day in some other way.
Feeding with other stock. Sheep should not run, or be fed, in yards, with any other stock. Cattle hook them, often mortally; and colts tease and frequently injure them. It is often said that “colts will pick up what sheep leave.” But well-managed sheep rarely leave any thing; and, if they chance so to do, it is better to rake it up and throw it into the colts’ yard, than to feed them together. If sheep are not required to eat their food pretty clean, they will soon learn to waste large quantities. If, however, they are over-fed with either hay or grain, it is not proper to compel them, by starvation, to come back and eat it. This they will not do, unless sorely pinched. Clean out the troughs, or rake up the hay, and the next time feed less.
Division of flocks. If flocks are shut up in small inclosures during winter, according to the northern custom, it is necessary to divide them into flocks of about one hundred each, consisting of sheep of about the same size and strength; otherwise, the stronger rob the weaker, and the latter rapidly decline. This is not so important where the sheep roam at large; but, even in that case, some division and classification are best. It is best, indeed, even in summer. The poorer and feebler can by this means receive better pasture, or a little more grain and better shelter in winter.
By those who grow wool to any extent, breeding ewes, lambs, and wethers, are invariably kept in separate flocks in winter; and it is best to keep yearling sheep by themselves with a few of the smallest two-year-olds, and any old crones which are kept for their excellence as breeders, but which cannot maintain themselves in the flock of breeding ewes.
Old and feeble or wounded sheep, late-born lambs, etc., should be placed by themselves, even if the number be small, as they require better feed, warmer shelter, and more attention. Unless the sheep are of a peculiarly valuable variety, however, it is better to sell them off in the fall at any price, or to give them to some poor neighbor who has time to nurse them, and who may thus commence a flock.
Regularity in feeding. If any one principle in sheep husbandry deserves careful attention more than others, it is, that the utmost regularity must be preserved in feeding.
