Protein meal is high in protein content and rich in amino acids, which can be used to replace protein feed such as soybean cake and fish meal in the feed market with shortage of soybean cake and fish meal. Protein powder is rich in protein nutrients, and does not contain toxic and harmful substances. It does not need to be reprocessed. It can be directly used as protein raw material and is a high value feed raw material.

Cattle feed

Using protein powder as concentrate can make the protein which can't be digested by rumen better digested and absorbed in small intestine. Linoleic acid is contained in protein powder, which can promote the lipid metabolism of cattle and the polymerization of essential amino acids.

Pig feed

The protein content of protein powder is directly related to the apparent digestible energy value of pigs. The raw materials with appropriate ratio of energy to protein or balance of essential amino acids and non essential amino acids have higher energy digestibility. The protein powder with different protein content (CP: 52% produced in Northeast, 47.4% and 32% produced in Beijing) is added to the basic feed of pigs, and the addition amounts are 20%, 25% and 30% respectively, The results showed that the apparent digestible energy of the protein powder containing 32% crude protein was higher than that of the control. The reason may be that the ratio of energy to protein was suitable.

Chicken feed

The egg production rate of laying hens can be increased by 15% with protein powder as the main feed. It can prevent chicken cartilage disease and other diseases, play a role in health care and growth promotion, and improve the quality of egg protein.
