Sheep can grazing throughout the year, but during the winter, due to withered grass, low nutritional value, grazing intake is low, as well as cold weather, and even can not be animal husbandry. Some ewes have been pregnant, lambs, breast-feeding, or young sheep are in a period of growth, rapid growth, need more nutrition. Therefore, every winter and autumn season, it is necessary to start stocking overwintering forage. According to the sheep's specific conditions and weather changes, the sheep can be fed in a timely manner to ensure that the sheep can safely pass winter. Lamb feeding before weaning mainly has the following advantages: First, speed up the growth and development of lambs, lay a good foundation for future fattening effects, and shorten the fattening period. Second, it is beneficial to the growth of twin or multiple lambs. Generally, the growth weight of the twin lambs or lambs is small, and the amount of milk supplied by the ewes is certain. The supplemental feeding in advance is helpful for the growth and development of the twin lambs or the lambs. Third, reduce the frequency of lambs' licking of ewes, so that ewes have enough time to eat and rest, so that the peak of lactation is maintained for a long time. Fourth, promote the development of the digestive system of the lamb, and exercise the ability to feed, so that the lamb can quickly adapt to the new feeding and management methods after weaning.
