For the cold and hot properties of feed, there are differences between warm and cold feeds. The former is suitable for the cold season. It supplies heat energy to the farmed animals or promotes the body to generate heat energy, strengthens the metabolism, increases the resistance to disease, and eliminates cold stress caused by internal cold and cold outside.
First, distiller's grains
Distillers' grains include distillers' grain and brewer's grains. In addition to being rich in protein and minerals, they also contain a certain amount of ethanol, which has a large amount of heat and is often referred to as "fire feed." It can improve digestive function, strengthen blood circulation, expand body surface blood vessels, and produce warm feeling. Feeding in winter, the effect of cold stress is obvious. Distillers grains are suitable for feeding rabbits, pigs and cattle, especially for beef cattle; brewers' grains are suitable for feeding chickens, ducks, pigs and cattle. Both of them have adverse effects on fetal and male functions, so they should not be used for pregnant women and grazing animals.
Second, root bark
The vegetable root bark contains minerals that can produce a cold-proof effect. When used as feed, it can enhance the cold resistance of farmed animals; vegetable celery root, alfalfa root, spinach root, cabbage root and other carrots, potatoes, sweet potatoes and other roots , can be used as cold feed. When using this kind of feed, pay attention to keep its skin.
Third, food
1. Soy beans, black beans. Soybeans are sweet and warm, fried with hot, warm feed, contain 37.9% of crude protein, both excellent vegetable protein feed, but also cold and warm feed. Black beans contain 36.68% crude protein, sweet nature, sweet, fried very hot, is a good cold warm feed.
2. Barley seeds. Warm and salty, warm feed. Feeding fattening pigs can obtain high-quality pork, feeding boars can improve reproductive performance, and breeding sows can promote development. Cooked effect is good.
3. Rice seeds. The glutinous rice is warm and bitter, and it is a warm feed. When feeding a lactating female rabbit, it can increase the amount of lactation. The glutinous rice can be used as a substitute for corn to feed rabbits.
Fourth, meat
Lamb and dog meat produce high calories, which is the preferred warmth and cold-resistant feed for winter carnivorous and omnivorous livestock and poultry. Animal liver contains more iron (the animal is particularly cold when it lacks iron) and is easy to absorb. In winter, appropriate animal feeding of some animal livers can supplement iron and keep warm. Freshwater prawn is warm and sweet, and it is a high-calorie feed. It has the effect of strengthening kidneys and strengthening yang and strengthening male functions. It is suitable for animals that suffer from cold and cold in winter. The salt-free shrimp can be used directly, and the salt-dried shrimp needs to be applied after the water is immersed in the salt.
