First, the conditioning of pregnant ewes
The first thing to do is to repair the pen in time in winter. The best choice for the pen is in the place with sunny wind and sunny weather. Please pay attention to the plastic film and straw in cold weather. The sheep's collar should be diligently filled with manure, frequently changing soil and keeping the house clean and warm. To give the sheep hot soup hot water, avoid feeding frozen grass, frozen water. Grab the sunny hours at noon and let the sheep go to the sun outside the house. Should pay attention to miscarriage, when the sheep anti-fright, slippery, do not take the steep slope, but the ditch, pregnant sheep out of the door to prevent crowding, extrusion and the top shelf to ensure the safety of pregnant sheep, to avoid miscarriage. Graze pregnant sheep, not too far away from home, to prevent tired or lambing, in order to deal with it in time.
To apply silage and ammoniated feed, the silage of corn stalks and sweet potato vines should be cut short to ensure the palatability of the sheep, and the gravid sheep can also be appropriately fed with soya beans soaked in warm water to meet the needs of pregnant sheep. Growth needs. Can also be added in the feed containing vitamin D and calcium, phosphorus substances, such as fish meal, bone meal, eggshell, etc., feeding cabbage leaves, carrots, sorghum, sweet potatoes, tung leaves and other vitamin-rich feed to supplement the lack of straw feed Nutrients to prevent sheep suffering from osteomalacia, resulting in dystocia, postpartum paralysis and fetal lamb congenital rickets, rickets, and even stillbirth.
Second, the lamb's care and cultivation
The milk within 5 days after the ewes are called colostrum is the only full-price natural food after the lamb is born. Colostrum contains 17% to 23% of protein, 9% to 16% of fat and other rich nutrients and antibodies, with nutrition, disease resistance and laxative effect. Lambs eat colostrum in time after birth, which plays an important role in enhancing physical fitness, fighting disease, and excreting meconium. Therefore, the newborn lamb should be allowed to eat as early as possible, eat more colostrum, the sooner you eat, the more you eat, the faster the weight gain, the stronger the constitution, the lesser the incidence, the higher the survival rate.
In the period of 6-60 days of the lactation period, goat's milk is the main food of lamb, supplemented with a small amount of forage. From birth to 45 days of age, it is the fastest growing period of lamb body length; from birth to 75 days of age is the fastest growing period of lamb weight. At this time, although the ewe's lactation is high, the nutrition is also very good, but the lamb still has to eat early and train the forage to promote the development of the forefoot and increase the source of nutrition. Usually after 10 days of age, the grass is given and the young hay is bundled and hung in the air to allow the lamb to feed freely. When training begins, you can put some semi-wet material that has been burned with boiling water in the feeding trough to guide the lamb to eat. The lamb will be eaten several times. Note that the temperature of the hot material should be the same as the milk temperature so as not to burn the sheep's beak. You can also feed cooked carrots, leaves, and high-quality dry grass. Afterwards, feed comminuted cooked black beans, bean cakes, corn, sorghum and other mixed feeds, and add some chopped succulent feed. Do not eat too much at the beginning of feeding. With the increase of age, you can gradually increase the amount of feed.
During the 2 months of milk and grass transition period to the weaning stage, the lamb gradually feeds mainly and supplements with breast feeding. Diversification of feed is required to promote normal development of the lamb. Dietary digestible protein is preferably 16% to 30%. Lambs should be properly exercised at this time. As the age increases, the lamb can be driven out of grazing. The weaned lambs are dewormed before they are transferred or sold.
