How to improve the survival rate of lambs?

(agricultural Wealth Network) how to improve the survival rate of lambs? Strengthening the supplementary feeding of lactating ewes the lambs at the age of 8 weeks after birth mainly rely on breast milk for growth. Ewe supplementary feeding is mainly in the late pregnancy and lactation period, the time is about four months. Good quality hay or concentrate should be selected for supplementary feeding. 1.5 kg of hay (alfalfa or wild hay is better), 1.5 kg of silage and 0.45 kg of concentrate can be fed daily. Within 3 days after lambing, if the ewe is in good condition, the concentrate can not be fed temporarily and only high-quality hay can be fed to prevent indigestion or mastitis. -- do a good job in the feeding and management of lambs. Lambs should eat enough colostrum 1-3 days after birth. For weak lambs and poor motherhood, artificial breast-feeding is needed. The method is: hold the ewe and push the lamb to the ewe's breast to suck milk. Within 7 days after delivery, do not lead ewes and lambs to windy places outside the house; after 7 days, ewes can go outside to graze properly. Lambs should be trained to eat grass from 15 to 20 days of age. At the age of half a month, 50g / d ~ 75g / d, 100g / d, 200g / d and 250g / d at the age of half a month, 100g / day, 200g / day and 250g / day at the age of 1 month ~ 2 months, 1 month and 2 months, respectively. The composition of the mixture is beans, bean cake, corn and so on, and it is best not to use cottonseed cake. Hay to alfalfa, peanut seedlings, willow leaves, etc., hay should be chopped. Feed concentrate first, then coarse feed, and properly feed green fodder and ensure adequate drinking water at the same time. Lambs are generally weaned at the age of 4 months, and one more weaning method is used, that is, the mother and son are separated and no longer gregarious. Do a good job in the prevention and control of lamb disease within a week of birth, lamb dysentery is the most likely to suffer from dysentery. Lamb dysentery is an acute intestinal infectious disease with severe diarrhea and neurological symptoms and high mortality. Comprehensive measures should be taken to prevent and cure the disease. 1. It is necessary to strengthen the feeding and management of ewes, especially pregnant sheep. Do a good job of catching fat in summer and autumn and keeping fat in early winter and early spring to ensure that the lambs are strong, have enough milk and enhance their resistance. two。 Keep the sheep house warm in winter and spring, pay attention to the sudden change of temperature, the temperature in the house should not be too low, and keep the sheep house dry. 3. Ewes should cut off the dirty hair around their breasts before lactation, and squeeze out a few drops of colostrum to let the lambs suck, and let the lambs suck breast milk in time after birth, which can enhance their immunity. 4. Feeding oxytetracycline 0.15g ~ 0.2g per lamb within 12 hours after birth, once a day for 3 days, can have a preventive effect. 5. Timely observation of the lamb, so that the disease is found in time, once found, immediately isolated, serious nursing treatment; sheep barn feces, bedding grass should be burned; the contaminated environment, appliances, etc., should be sprayed and disinfected with 3% or 5% Lysol water. 6. The combination of drug treatment and nursing should be taken for sick lambs. The prescriptions of commonly used drugs are as follows: ① sulfonamidine 0.5g, tannic acid protein 0.2g, bismuth subnitrite 0.2g, sodium bicarbonate 0.1g, fed with water 3 times a day for 3 ~ 4 days. ② oxytetracycline 0.2g ~ 0.3g, fed with water twice a day, 200000 units of penicillin and streptomycin were injected intramuscularly at the beginning of the disease. For lambs with abdominal pain and salivation, ③ can be subcutaneously injected with 0.05% atropine sulfate 0.2ml ~ 0.3ml, and the dose should be strictly controlled during injection. For lambs with severe dehydration, 20ml ~ 30ml of glucose saline can be injected intravenously. ④ garlic 20 ~ 25 grams, peel, wash and mash, with water irrigation, 2 times a day, continuous irrigation for 3 days. ⑤ was treated with lactic acid 30ml ~ 50ml and brown sugar 50g, 2 ~ 3 times a day until cured. ⑥ was given 15ml dried poplar flower juice (oral dose) once or twice a day. The female champion in breeding is worthy of her reputation.
