How to solve the problem of raising sheep in winter when the weather is cold and the forage grass is low in nutrition

In winter, the weather is cold, the night is long, the forage grass wilts, the forage grass nutrition is low, and the sheep lose a lot of heat. At this time, most ewes are pregnant, and during the first overwintering period, the sheep need more nutrients. Once they are not properly raised, the sheep will lose fat and even die.

Sheep

First, the main countermeasures:

1. The temperature in winter is low, and the sheep shed in summer and autumn is no longer suitable for sheep growth, so it is necessary to repair the sheep house. The sheep house faces south with plenty of sunshine, good ventilation, dry hygiene and good warmth. In front of "the Beginning of Winter", block the wind tunnel to ensure that the roof is not leaking rain, the four sides are airtight, and the ground is not wet. The sheep shed that is dilapidated, leaky 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 house to prevent the invasion of "thief wind" and keep the sheep house warm and dry.

2. Reasonable grazing: first of all, pay attention to the grazing time. Sheep graze in summer is in the morning or late afternoon, while in winter, except for blizzard weather, grazing should be carried out every day, around noon every day, about 4 hours. When the weather is extremely cold, grazing nearby. This can keep sheep exercising and reduce the energy consumption of sheep on the grazing road.

The second is the way of grazing. In early winter, dry leaves are still abundant, and hardy plants also grow. Graze at this time, go out late and come home early, and let the sheep eat more grass. When grazing, you should choose pasture with sunny shelter, high terrain and good water source, first put shady slope, then sunny slope, first ditch bottom, then ditch slope, first low grass, then high grass, so that sheep walk less and eat more grass; insist on going out against the wind and returning to the wind, so that sheep gradually adapt to the cold; ewes are close to the pasture, breeding sheep and Capricorn sheep are put far away, lean sheep are grouped alone, and more pasture is herded.

The third is to strengthen supervision. When grazing, do not be too tired, walk slowly, do not jump trenches, do not climb steep slopes, do not walk on the ice path, do not frighten sheep, do not let sheep eat muddy grass, frosty grass, and rainy grass; when returning to grazing, they should control the sheep well and avoid chasing and rushing; keep the door in and out of the trap steady, strictly prevent crowding, and cause miscarriage.

3. In the withered grass period in winter and spring, the nutrition of sheep is not enough by grazing alone, and it is suitable for 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. Timely supplementary feeding can also increase sheep production, such as sheep supplementary feeding at night and in rainy and snowy weather, dry or silage forage and hay, mostly peanut seedlings, bean straw, weeds, etc., and 0.5-1.0 kg per day for an adult sheep. If the number of sheep is small, you can put the grass in the basket and then hang it up and feed it; 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 feed it at a height where the sheep can eat. Supplement the concentrate, which can be made up of rice flour, cornmeal, rice bran and bean cakes, which can be fed once in the evening, 0.2-0.3 kg per adult sheep per day. In addition, we should pay attention to the addition of salt, vitamins and trace elements, and add green succulent feed such as carrots to lambs, breeding rams and pregnant ewes.

4. If the forage is dry in winter, there must be plenty of drinking water. Drink once at 2 pm every day, and drink again after returning to grazing in the evening. Generally drink warm water, the water temperature is about 25 ℃, do not drink cold water or ice slag water. Properly add salt, do not drink water first, and then feed salt, otherwise it will cause "water top tire" phenomenon.

5. prevention and treatment of diseases and do a good job of sanitary disinfection. Low temperature in winter, sheep are prone to diseases such as colds, fever and other diseases, in breeding, we should pay close attention. The enclosure should be inspected frequently to keep the enclosure, bedding, drinking water and forage clean. If necessary. Thoroughly disinfect the enclosure to ensure the cleanliness and hygiene of the sheep's body surface, at the same time, do a good job in the prevention and control of sheep diseases, biological treatment of feces, prevention and control of sheep diseases and deworming, especially sheep dysentery, colibacillosis, sheep streptococcosis and colds, and commonly used insect repellents are used to prevent and deworming sheep to ensure that sheep are healthy and resistant to cold winter.
