In winter, in addition to the need for feed nutrition, pregnant sheep and frail sheep need higher feed nutrition levels. Therefore, winter is the key to raising sheep. Adequate forage
In the early winter of cold winter, the adult sheep store 200kg to 300kg of hay each, according to the local conditions, it can collect and store various crop straws, and adopt the method of silage, micro-storage and dry powder wet mixing to feed the sheep. Dry grass, peanut vines, sweet potato vines and green pea stalks are good forages of sheep in winter. Prevention of pests
Do a good job of prevention of sheeppox, sheep contagious pleuropneumonia, sheep epidemic, phlegm, enterotoxemia triple inactivation of fatigue seedlings. Insecticides can be given per gram of body weight with oral imidazole 12.5 mg to 25 mg or intramuscularly with levamisole and 10 mg per kilogram of body weight, and once every 7 days, the ideal insect repellent effect can be achieved. Reasonable grazing
In the early winter, use sunny weather to extend the grazing time and try to allow the sheep to eat more food to lay the foundation for wintering. After entering the winter, some cold-tolerant plants can be used to feed the sheep after the ice has dissolved and dried in a windless sunny weather. Rain and snow do not grazing.
Strong and weak grouping
After winter, according to the sheep's age, sex, physique, etc., the sheep are grouped rationally, and the sheep with similar body condition are grouped together and reared in groups so as to take care of the weak lambs. In the winter, the combination of grazing and supplementation is adopted, and rain and snow are used for feeding the whole group. For the poor health, long-term empty and low performance sheep sheep cage, feed, feed fattening market. Poly warming
Check the sheep house every day in winter, use straw, diesel and plastic cloths outside the northwest wall to set up a windproof reflective wall to ensure that the temperature of the sheep house is over 10°C.
Scientific feeding
In the winter and spring seasons, it is necessary to properly match forage grass feed and supply it twice in the morning and evening.
In the feeding of forage grass should be taken first, after the green, with more varieties and less frequent meals, timely addition methods to ensure that the sheep have more adequate, palatable and more comprehensive nutritional feed forage. The daily food intake on hay should account for 6% to 8% of their own weight, and the fresh grass should account for more than 20% of their own weight. In order to increase the amount of feed intake, regular light salt water can be sprayed on the forage to allow the sheep to be full of abdomen.
In order to improve the fattening effect, the concentrate can be supplemented with 1%-2% of body weight. The formula includes 32 kg of corn per kilogram of fine material, 8 kg of fried beans or cakes, and 9 kg-10 kg of wheat bran. Salt 0.5 kg, urea 0.5 kg, 0.5 kg all-round additive, crushing and mixing, quantitative feeding every night. Also let the sheep have enough clean drinking water. With this method of feeding, the average monthly weight gain of mutton sheep can reach 6 kg to 8 kg per month, and the maximum weight can be increased by more than 10 kg.
Birth care
The ewes during pregnancy should be inspected frequently during the winter, and when they reach the end of their production period, they must receive production in a safe and timely manner, and at the same time do a good job of insulation and frost protection in the delivery room. The delivery room temperature was maintained at 18°C~20°C, and then gradually lowered to room temperature. At the same time, let the lambs eat breastmilk, which has an important role in strengthening the body, resisting cold, resisting disease and excreting meconium. Newborn lamb eats early, eats more colostrum, has faster weight gain, has stronger constitution, less morbidity and high survival rate.
