In the cold season, appropriate feeding of some cold-resistant feed can strengthen the body's metabolism, enhance physical fitness, increase resistance to disease, relieve cold stress, and thus promote pig growth and development. Common cold-resistant feeds are:
1. Distillers' grains include distillers' grain and brewer's grains. In addition to being rich in protein and minerals, it also contains a certain amount of ethanol, which has a high heat content. It is often referred to as "fire feed," which can improve digestion and blood circulation. , expansion of the body surface blood vessels, resulting in a warm feeling and other effects. In winter, the effect of cold stress is obvious. Distiller's grains have adverse effects on the function of the fetus and the male, so it is not suitable for pregnant women and male veterinarians.
2. The root barks of root bark vegetables contain minerals that can produce warming effect. When used as feed, they can enhance the cold resistance of the pigs; vegetable celery root, barnyard root, spinach root, cabbage root and other vegetable waste, and carrots, Roots such as potatoes and sweet potatoes can be used as cold feed. When using this kind of feed, be sure to keep its skin.
3. Soybeans are warm, sweet and fried, and use hot food. They are warm feeds and contain 37.9% of crude protein. They are both excellent vegetable protein feeds and cold and warm feeds. Black beans contain 36.68% crude protein, sweet nature, sweet, fried very hot, is a good cold warm feed. Barley is warm, salty, warm, and has good ripening effect.
