Cold-resistant breeding techniques for cattle and sheep

The cold-resistant feeding technology of cattle and sheep is mainly used to reduce the adverse effects of rainy, freezing and other disastrous weather and disaster recovery. Main technical contents: 1. Renovate the fence house to protect against cold and keep warm. The windows of the enclosure should be closed with plastic film to plug the loopholes and prevent the wind; the glass of the windows should be cleaned to facilitate daylighting; cover the windshield. Calves, lambs and parturient cattle and sheep can light a fire in the enclosure to keep warm, and farmers with conditions can install infrared heating lights. 2. Increase the feed energy appropriately. In bad weather conditions, improper breeding of pregnant animals can easily lead to miscarriage of pregnant mothers, or even death of both mothers and offspring. In order to increase the supply of concentrate feed, cows should be fed 1 Mel 2 kg concentrate per day, and the concentrate supply of sheep should be increased by 20%. At the same time, more succulent feeds such as silage and carrots can be fed to farmers with conditions, and some bone meal and salt can be added appropriately. 3. Feed hot porridge and hot water. The concentrate had better be made into hot porridge of about 38 ℃, which is not only palatable and easy to digest, but also can enhance the cold resistance of the body. At the same time, it is necessary to maintain adequate drinking water at a suitable temperature, and the temperature of water should be 37 ℃. 4. Strengthen the feeding and management. Enclosure frequently mat grass, change grass frequently, clean frequently, remove dung frequently; maintain moderate feeding density and keep the air smooth. 5. Exercise and brush the cow body properly. When the weather is clear, release the cow to bask in the sun and wipe the cow body at the same time, which can not only prevent the occurrence of skin diseases and parasitic diseases in vitro, but also promote the blood circulation of cattle and improve the ability to resist cold and cold.
