How to keep sheep safely through the winter with low temperature and little green grass?

Adequate feed: sufficient protein-rich bean straw, pod peel, alfalfa, sweet potato seedlings, leaves, silage, ammoniated feed and so on. These are the necessary fodder for sheep to survive the winter safely, so keep them in reserve in autumn. Store corn and other concentrate for supplementary feeding. Soybean straw and other straw feed should be crushed before feeding.

Sheep

Repair the sheep house: the sheep house should be well ventilated, dry and clean. Before winter comes, the tuyere should be blocked so that the top does not leak, the ground is not wet, and the four walls are airtight. Before the beginning of winter every year, sheep should be adjusted according to the nutritional status of sheep, so that sheep with similar body conditions can be grazed in a group and make full use of pastures. The weak sheep are near, and the strong sheep are far away, so as to take care of the 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. In late autumn and early winter, sheep can be dewormed with trichlorfon or thio-dichlorophenol.

Strengthen supplementary feeding: after the beginning of winter, the forage grass withered, grazing alone can not meet the nutritional needs of sheep. Every day before grazing and after grazing, supplementary feeding should be carried out at 4-7 am and 3-5 pm, and should be carried out in the open circle outside the house. Each sheep was fed with silage corn straw 1kg, concentrate 100m / 250g, bone meal 5m / m 7g and salt 5m / 10g daily, 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 grass, 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 sheep fat is good, make use of the distant pastures as far as possible, leaving nearby pastures for lambs and thin sheep. Before going out to graze in the morning, open the leeward doors and windows of the sheep house to release heat, and then drive the sheep out when the temperature inside and outside the house is close to, so as not to catch cold.
