Functional lipid for improving animal production performance under low-protein daily ration and preparation method thereof

Technical Field

The invention relates to the technical field of feed, in particular to functional lipid for improving the production performance of animals under low-protein daily ration and a preparation method thereof.

Background

In order to achieve the optimal production performance of animals, a large amount of high-protein feed raw materials such as soybean meal, fish meal and the like are often required to be added in the preparation process of a feed formula, so that the amino acid level of an amino acid metabolic library in an animal body is improved, and the secretion of an I-type insulin-like growth factor is stimulated, thereby improving the growth speed of the animals.

In order to improve the growth speed of animals, the processing formula of the feed comprises the following components: if the pig feed is added with more than 20 percent of soybean meal and more than 3 percent of fish meal, the protein of the feed formula reaches more than 20 percent; for example, the aquatic feed bean pulp accounts for 30-40%, the fish meal accounts for 20-40%, and the feed formula protein accounts for 40-50%.

The prior animal feed has the following defects and defects: china needs a large amount of imported soybeans and Peru imported fish meal from America and Brazil, for example, in 2021, China imports more than one hundred million tons of soybeans and more than 150 million tons of fish meal, which is unfavorable for grain safety and wastes foreign exchange reserves of China; in addition, too high protein that the animal can not digest is discharged with the excrement, which is not environment-friendly.
