Winter lambs have the characteristics of significant primary birth, fast development, high meat production and high wool production. However, at birth, it is in severe winter. The lack of green feed is very detrimental to the growth and development of lambs. Therefore, raising lambs in the winter should do the following five steps. First, timely feeding colostrum. The lamb is allowed to feed colostrum as soon as possible within 2-3 hours after being born, because the colostrum is rich in nutrients and easy to absorb. The content of protein is 4 times that of conventional milk and contains more antibodies. Colostrum can not only clean up the gastrointestinal tract, but also inhibit the proliferation of bacteria in the digestive tract and enhance the ability of the lamb to resist diseases. Second, to strengthen the supplementation of lactating ewes. Ewes must not be grazing within 2 weeks after giving birth, and must be fed and properly fed formula feed. The formula is: corn 50%, cake 26%, bran 24%. According to the ewe's lyrics, single lambs or double lambs, each ewes supplements 0.6-0.8 kg of fine material daily and 4-5 kg ​​of high quality hay. In addition, attention should be paid to supplementing mineral feeds and succulent feeds so that the ewes have sufficient milk to meet the growth and development of the lambs. Third, early to make up forage. After 30 days of the lamb’s birth, the ewes’ milk production cannot meet the needs of the lambs. Lambs must eat early. Generally, after 15-20 days of birth, lambs should be trained to eat nutritious, good-quality, digestible feeds such as carrots and shreds. Corn and so on. After 25 days of age, it is fed with corn, cakes, bran and other mixed concentrates to promote the development of the digestive organs of the lamb. Each lamb is supplemented with 60 grams of concentrate and 5 grams of salt. Fourth, the sheep house cold insulation. Newborn lambs have short wool, poor cold resistance and are prone to cold. There must be no holes in the wall of the shed of lambs, and the doors should be covered with wind curtains to keep the temperature within 10°C. Fifth, prevention and treatment of diseases. Lamb adaptability and resistance are very weak, so always pay attention to the lamb's state of mind, appetite and changes in faeces. Generally speaking, oxytetracycline 10 mg should be taken within 24 hours of birth, twice a day, for 3 days, which can reduce the occurrence of diseases. Once the disease is found, it should be treated immediately. If the lamb is found to be diarrhea, 0.5 g of sulfamethoxazole and 0.2 g of sodium bicarbonate can be taken orally once a day for 3 times; or 5-10 million units of penicillin can be given intramuscularly twice a day; 0.2-0.3 g of oxytetracycline can also be used. clothes. When a lamb suffers from pneumonia, it can be injected intravenously with 5-10 ml of 10% sulfadiazine and 20-30 ml of 25% glucose, or mixed with 10-600,000 units of penicillin and 10-20,000 units of streptomycin. , 2 times a day for 3 days.
