Winter lamb cultivation techniques
January-February is the season of winter lamb production. In order to improve the survival rate of lambs and develop good winter lambs, the following measures must be taken in feeding and management: 1. Strengthen the feeding of lactating ewes, and after birth Eight-week-old lambs rely mainly on breast milk for growth, so supplementation of ewes has a lot to do with the growth of lambs. Supplementary feeding is mainly in late pregnancy and lactation, about 4 months. Supplementary feeding should choose good quality hay or fine material, daily supplement hay 2 kg (with safflower, grass or wild grass as well), 1.5 kg of silage, 0.5 kg concentrate. Within 1-2 days after lambing, if the ewes have a good lye, they may not feed the concentrate but only feed quality hay to prevent indigestion or mastitis. Pay attention when feeding the hay. Do not put the grass in the hay and contaminate the hay. 2, do a good job of feeding and management of lambs. The colostrum should be eaten 1-3 days after the lamb is born (ejaculation within 5-7 days after delivery). Lambs usually suck their own milk after birth, but to weak lambs and poorly mothered ewes, the lambs are pushed into the breasts of the ewes and sucked. Do not bring the ewes and lambs to windy places outside the house when they are 3-7 days postpartum. After 7 days of age, the ewes will be allowed to go outside to eat herbivores, but do not go too far, and let the ewes return at noon. Let go of the lambs; never let the lambs go outside to graze, otherwise the lambs are susceptible to disease. When lambs are 15 to 20 days old, they should be trained to graze and feed 50-80 grams of mixed ingredients every day. For 1-2 month old lambs, 100 grams of supplements should be provided, supplemented with 200 grams for 2-3 months of age, March-April. 250 grams of supplemental feeding, the composition of the mixture of beans, bean cake, corn, etc. as well, it is best not to feed cottonseed cake. The hay should be made of red flowers, grasses, weeds, peanuts, willow leaves, eucalyptus leaves, etc. The hay should be chopped and placed in the trough. Feed the concentrate, feed the coarse material, and feed the green feed. Make sure the lamb has enough water. Lambs are usually weaned at 4 months of age, and weaning methods are used once more, ie the mother is separated and no longer gregarious. 3, disease prevention and control of the lamb. This is one of the keys to improving the survival rate of lambs. Lambs born within a week are prone to dysentery and have a high mortality rate. Pregnant ewes are malnourished, improper nursing of the lambs, and cold and wet sheep houses can cause lamb dysentery. Therefore, comprehensive prevention and control measures should be taken. (1) For ewes, especially pregnant sheep, it is necessary to strengthen the feeding and management. Do a good job of summer and autumn harvest and winter early spring to ensure that the lambs produced are robust, and ensure that the milk is sufficient to enhance the resistance of the lamb. (2) Sheep homes should be kept warm in winter and spring. Always pay attention to sudden changes in temperature. Indoor temperature not less than 10 degrees Celsius; often keep the sheep house dry and sanitary. (3) Lambs should be promptly brought to colostrum after birth in order to enhance their immunity. The ewes should cut off the dirty hair around their breasts before breast-feeding, and squeeze a few drops of colostrum to lick the milk. (4) Within 12 hours after the lamb is born, oxytetracycline can be fed, each 0.15-0.2g, once a day, and fed for 3 days. (5) Observe the lamb regularly and make sure that the disease is detected early. Once the lamb is found to be ill, it should be immediately isolated, serious care, and timely treatment; sheep house excrement, bedding to be burned; contaminated environment and soil, utensils, etc. to use 3-5% Su child spray disinfection. (6) The treatment of lambs should be combined with medication and care. Drug prescription can be one of the following. One is: Sulfamethoxazole 0.5 g, citric acid protein 0.2 g, bismuth subnitrate 0.2 g, bicarbonate sodium bicarbonate 0.2 g, water-adjusting feeds, 3 times a day, and even 3-4 times. The second is: Oxytetracycline 0.2-0.3 grams, water-feeding service, 3 times a day; the beginning of the disease can be used 200,000 units of penicillin, streptomycin, intramuscular injection. The third is: for the abdominal pain, more than the flow of the lamb, can be subcutaneous 0.05% atropine sulfate 0.2-0.3 ml, to strictly control the dose, the severe dehydration of the lamb, intravenous glucose can be 20-30 ml of normal saline. The fourth is: 20-25 grams of garlic head, peeled, washed, smashed, water fed, 2 times a day, even irrigation for 3 days. The fifth is: 30-50 ml of lactic acid, plus 50 grams of brown sugar, 2-3 times a day, until healed. Sixth: 15 ml of dried poplar flowers (15 ml) (one oral dose) and usually 1 or 2 lambs per month can be cured. (Mei Qinghui rural knowledge)
