Scientifically modulating feeds aims to increase feed digestibility and nutritional value, enhance palatability, increase feed intake for livestock and poultry, and fully exploit and utilize as much feed resources as possible. Here are a few simple ways to scientifically modulate feeds. First, the short saying goes: "Courtesy grass three knife, did not expect to be on board." Straw, sweet potato vines, green grass, straw, etc., must be short before feeding. Feeding cattle straw can be as short as 2 cm to 3 cm, feeding horses, cockroaches as short as 1 cm to 2 cm; pigs feeding sweet potato cane as short as 1 cm to 2 cm. In order to eat chewing and digestion of livestock and poultry to reduce waste, it is also convenient to mix with bran or concentrate. Second, the use of raw grain to feed livestock and poultry, often due to chewing is not fine and wasted feed, affecting digestion and absorption. Therefore, where corn, peas, broad beans, wheat, sorghum, sweet potatoes, etc. are used as feed, they must be crushed and then fed. The degree of grinding thickness depends on the type of livestock and poultry being fed. Can not be too coarse to wear, not conducive to digestion; can not be too fine, affecting chewing, so that saliva can not be fully mixed with the feed, affecting digestion and absorption. Third, fried fragrant soybeans, peas, sorghum fried yellow, crushed into coarse grain feed livestock and poultry. After frying and frying, the protein is crispy and coking, which is palatable and easy to digest. It is also easy to mix in the green roughage with the feeding, the palatability is increased, and it is easy to increase the weight and save the material. Soften corn, peas, beans, soybeans, wheat, sorghum, and so on, it is best to soak for some time with light salt boiling water, so that it is fully softened before feeding. Fourth, silage is storage of green fodder in a variety of dedicated silo containers (plastic bags, pits, tanks, pools), under anaerobic conditions for lactic acid fermentation, produce lactic acid, protect the nutrients in the green material from loss, Improve green feed utilization and digestibility. 5. Alkalization The crude material was alkalized with 1% quick lime milk. The dry feed (straw, wheat straw, dry rattan, hay, etc.) is put into containers (barrels, cylinders, and pools) first, and the cover boards are pressed tightly, and the lime milk is poured into the container so that the water can submerge the feed. Soaked for 24 hours, you can remove and feed without washing. After the crude material is alkalized, the animal can fully digest and absorb its nutrients. Six, saccharification, saccharification and fermentation, with 100 kg of crude feed with a good feed meat song 3 kg to 5 kg, add water, 100 kg (to be hand-knead into a group, not dripping is appropriate) Stir evenly, into the cylinder, cover The plastic film is sealed. When the temperature rises to about 40°C, the feed is pressed tightly and the temperature is sealed and controlled. After the feed is saccharified, it has the characteristics of acid, sweet, fragrant, soft and cooked, and the livestock and poultry prefer to eat. 7. Ammonialization: Shorten the rough material into 2 cm to 3 cm, and put it into a prepared stone tank or cement pool. Add ammonia water and coarse material into layers. Add 15% to 17% of ammonia water per 100 kg of coarse material. 12 kg. After the rough material is filled up and sealed, it can be taken out after about 10 days of storage. Before the feeding, the residual ammonia should be volatilized. 8. After the dried grass and vines are harvested, they must be air-dried quickly to preserve their nutrition. If the water does not quickly evaporate, enzymes and microorganisms will multiply quickly and directly destroy and consume nutrients in the feed. However, it cannot be exposed to sunlight for a long time to reduce the loss of carotene and chlorophyll. 9. Use basidiomycetes to decompose the lignocellulose in the coarse material to form bacterial proteins and improve feed nutrition. The practice is to first shorten or crush the coarse material, add the appropriate amount of water and inorganic nitrogen, and inoculate the basidiomycete to make it abundant. Reproduction, the formation of bacterial protein. It is a good way to increase the crude protein.
