In winter, the weather gradually turns cold. If you do not do a good job of warming and freezing, livestock can be easily frostbite, and serious animal deaths can result. In this regard, Sun Shiying, a professor of animal sciences at the Northwest A&F University, reminded farmers that they should adopt a series of effective anti-freezing measures for livestock during the winter months, and read the animal's “heat preservation and antifreeze warp”.

Repairs

In winter, the intrusion of cold winds will cause livestock colds and pneumonia and other diseases. Therefore, the pens should be built on the terrain of Gaozao and Xiangyang, and the gaps between the roof and the walls must be promptly repaired. Arched, ridged, umbrella-shaped or single-slope, sunny plastic shed. Plastic sheds can be heated and heated, which can increase the temperature around 5°C, which is conducive to the growth and weight gain of livestock. Sawdust and rice husks shall be added to the enclosed sheds. Vents shall be left in the sheds. The windows and ventilation holes of the sheds shall be more than 1-1.5 meters above the ground in order to discharge ammonia and moisture from the premises.

Cold insulation

The doors and windows of the pens can be covered with grass curtains or the entire doors and windows can be covered with plastic sheets to keep warm and cold. In the northwest of the northern wall of the pen house, a wind barrier or windrows are used to make winds to prevent the northwest wind from invading the pen. In the winter, 15 cm thick corn leaves or other hay should be placed on the livestock bed, which can absorb moisture, remove moisture, absorb harmful gases, and increase the temperature of the livestock bed. You can also take a straw shed where soft hay is stacked to keep the animals warm. The greater the humidity in the pens, the colder the livestock feel and the more likely to cause skin diseases, respiratory diseases, infectious diseases, and parasitic diseases in livestock. In order to prevent moisture and leakage of rain, it is necessary to diligently change the hay and loose soil, let the livestock defecate urine, keep the livestock lying in a clean and dry place, and provide a comfortable living environment for livestock to promote the growth and development of livestock. And health.

Carefully feeding

When formulating livestock diets, energy feeds such as sorghum and corn should be appropriately increased. The feed is fed after fermentation and it is necessary to drink warm water. The supply of feed should be adequate, around zero every night, plus one night diet to enhance the ability to resist cold and disease and promote rapid growth. In the feed can be added to blood circulation, spleen dampness, cold dispelling cold Chinese medicine, can not only promote the fast fattening livestock, but also cold resistance. Such as hawthorn, herb, orange peel, malt, Chuanxiong, licorice, etc., feed a small amount of feed in the morning and feed once a week.

In winter, the number of domestic animals in the house can be increased by one-third to one-half as much as usual, allowing the animals to warm up with each other's body temperature, and the fact that the livestock can dissipate more heat can increase the temperature. The cages should be filled with new livestock and should be carried out at darkness. They should be sprayed with the liquor or odor of low concentration and then sprayed on the body of the animals. The keeper must observe for several hours to prevent fighting.
