How do sheep survive winter safely?

(agricultural get Rich Network) how to make sheep survive the winter safely? -- sufficient feed should be prepared with bean straw, pod peel, alfalfa, sweet potato seedlings, leaves, silage and ammoniated feed, etc. These are good fodder for sheep to survive the winter, so we should pay close attention to harvest and reserve in autumn. Store corn and other refined feed for supplementary feeding. Soybean straw and other straw feed should be crushed and fed. -- repairing sheep houses requires good ventilation, dryness and cleanliness. The tuyere should be blocked before winter, so that the top is not leaking, the ground is not wet, and the walls are not ventilated. Before the beginning of winter every year, sheep should be adjusted according to the nutritional status of sheep, so that sheep in the same condition form a herd for grazing and make full use of the pasture. Weak sheep graze near and strong sheep graze far away to take care of weak sheep. Sheep with long illness, small and thin body, long-term emptiness, old age and low production performance should be well fattened in autumn or eliminated in time. At the end of autumn and the beginning of winter, trichlorfon or thio dichlorophenol can be used to disinfect sheep. After strengthening supplementary feeding into winter, the forage grass will wither, and grazing alone can no longer meet the nutritional needs of sheep. Supplementary feeding should be carried out before and after grazing every day, 4: 00 ~ 7: 00 in the morning, 3 ~ 5 in the afternoon, and in the open circle outside the house. Each sheep was supplemented with silage corn straw 1000 g, concentrate 100g ~ 250g, bone meal 5g ~ 7g, salt 5g ~ 10g, drinking water twice a day. The supplementary feeding amount of ewes with twin lambs should be doubled and succulent silage should be replenished as much as possible. Do a good job of grazing sheep in and out of the enclosure, grazing, returning to grazing, feeding, drinking water should be steady, strictly prevent crowding. Choose pastures that are rich in forage, warm and sheltered from the wind, and graze for more than 6 hours a day except in windy days. According to the topography and forage conditions, it is necessary to put the sunny slope first, then the shady slope; the distance first, then the near place; the bottom of the ditch first, and then the slope of the ditch; the dwarf grass first, and then the tall grass. While the fat is good, make use of the distant pastures as much as possible, leaving nearby pastures for lambs and thin sheep. Before going out to graze in the morning, open the doors and windows of the leeward direction of the sheep house to release heat, and then drive out the sheep when the temperature inside and outside the house is close to, so as not to catch cold.
