What are the main points of raising sheep in winter?-- 1. Repair the sheep barn. The sheep house is required to sit north and south, sunny, well-ventilated, dry and hygienic, and keep warm. The wind tunnel is blocked in front of "the Beginning of Winter" to ensure that the roof is not leaking rain, the four sides are airtight, and the ground is not wet. Sheep sheds that are dilapidated, rainy and ventilated should be repaired in time; in the cold winter, grass curtains or cotton door curtains should be hung at the exit and ventilation of the sheep shed to prevent the invasion of "thief wind". -- 2. Reasonable grazing. In winter, in addition to blizzard weather, should adhere to daily grazing, especially in early winter, dry leaves are still relatively rich, hardy plants also grow, then we should pay close attention to grazing, go out late and come home early, and let sheep eat more grass as much as possible. When grazing, we should choose pastures with sunny shelter, high dryness and good water supply, and pay attention to putting shady slopes before sunny slopes, ditch bottom before ditch slopes, low grass before high grass, so that sheep walk less and eat more grass; adhere to going out against the wind and returning to the wind, so that sheep can gradually adapt to the cold; ewes are placed near pasture, bred sheep and Capricorn are placed in distant grasslands, and lean sheep are put in separate groups in grassy pastures. Strengthen care to prevent sheep from eating muddy grass, frosty grass and rainy grass. -3. Replenish the feed in time. In the withered grass period in winter and spring, it is difficult for sheep to meet their nutritional needs only by grazing, so it is appropriate to carry out half-day grazing and half-day supplementary feeding. In this way, it can not only reduce physical exertion, but also help to keep fat and gain weight. The hay was supplemented in winter and spring, mostly peanut seedlings, bean straw, weeds and so on, and an adult sheep was fed 0.5 kilograms per day. If the number of sheep is small, you can put the grass in the basket and then hang the basket for feeding; when the number of sheep is large, you can make a grass rack to feed the grass, and you can tie up the grass and hang it at a height where the sheep can eat. Supplement the concentrate, which can be made up of rice flour, corn meal, rice bran and bean cake, which can be fed once in the evening, and each adult sheep is fed 0.2kg / day. In addition, we should pay attention to the addition of salt, vitamins and trace elements; for lambs, breeding rams and pregnant ewes, but also add some green succulent feed such as carrots. -- 4. Make sure you drink water. If the forage is dry in winter, adequate drinking water must be ensured. Generally, you can drink at 2 pm every day, and drink again after returning to grazing in the evening. The water temperature is about 25 ℃. Do not drink cold water and ice residue water to the sheep. -5. Pay attention to protecting the fetus. In winter, most ewes are pregnant, so we should pay attention to do a good job of protecting the fetus. When grazing, do not be too tired, walk slowly, do not jump trenches, do not climb steep slopes, do not take the ice path, do not frighten the sheep; when returning to grazing, you should control the sheep and avoid running after them; keep the door in and out of the circle steadily, and strictly prevent miscarriage caused by congestion.
