How to improve the survival rate of lamb
1. Feed more ewes. The supplementary feeding time is mainly in the late pregnancy and lactation period, and the time is about 4 months. For supplementary feeding, choose good-quality hay and concentrated materials. Daily supplementary feeding is 1.5 kg of hay (alfalfa or wild hay), 1.5 kg of silage and 0.45 kg of concentrated materials. Within 3 days after lambing, if the ewe has good fat quality, you can temporarily stop feeding the concentrate and only feed high-quality hay to prevent indigestion or mastitis.
2. Care for the lamb carefully. Lambs have to eat enough colostrum 1 to 3 days after birth. For weak lambs and poor motherhood, artificial assisted feeding is required. Within 7 days after giving birth, do not lead the ewes and lambs to a windy place outside the shed; after 7 days, the ewes can go outside the shed to eat grass appropriately. Lambs should be trained to eat grass when they are 15 to 20 days old. Supplementary feeding mixture 50g~75g/day at half-month age; supplementary feeding 100g/day at 1 month to 2 months old; supplementary feeding 200g/day at 2 months to 3 months old; 3 months to 4 months old Supplement 250 g/day at age. The composition of the mixture is preferably beans, naked oats, and corn. The hay is preferably alfalfa, green hay, etc. Feed the concentrate first, then the coarse material, and appropriately add green fodder "such as carrots", while ensuring sufficient drinking water.
3. Prevent diseases in time. A week after the birth of lambs, they are prone to dysentery. Lamb dysentery is an acute intestinal infectious disease with severe diarrhea and neurological symptoms, high mortality, and comprehensive prevention and treatment measures should be taken. For ewes, feeding and management must be strengthened. Do a good job of maintaining fat in winter and early spring to ensure that the lambs produced are healthy and have sufficient milk. Keep the sheep shed warm in winter and spring, and the temperature inside the shed should not be too low; and keep the sheep shed dry. Before breastfeeding, the ewes should cut off the dirty hair around their breasts and squeeze out a few drops of colostrum before allowing the lambs to suck. Lambs should be sucked into breast milk in time after birth to strengthen their immunity. Start feeding oxytetracycline within 12 hours after the lamb is born, 0.15 g ~ 0.2 g each time, once a day for 3 days, which can have a preventive effect. The lamb should be observed in time, so that the disease can be detected and treated in time.
