Problems solved by technology

[0005] However, the use of chemical methods to protect lysine has unstable effects and does not have wide application value. Therefore, the use of physical methods to coat amino acids shows good prospects.

Abstract

The invention relates to a lycine additive and relative preparation. The invention is characterized in that the additive comprises three layers while the inner layer is lycine, the middle layer is acroleic acid resin IV, and the outer layer is the mixture between acroleic acid resin and hydrogenated vegetable oil. The invention uses acroleic acid resin IV and hydrogenated vegetable oil to protectthe lycine, therefore, the additive is stable with low release rate in the cud, but high release rate in the stomach and small intestine, to improve the lycine adsorption of ruminant in small intestine, to improve the protein utilization.

Description

Technical field [0001] The invention relates to a lysine additive and a preparation method thereof, in particular to produce a protein nutritional additive effective for ruminants by protecting the lysine nutritional additive. Background technique [0002] The lack of protein feed resources and environmental protection and other reasons require improving the utilization of protein by animals. In recent years, experiments on pigs and chickens have proved that the balance of amino acids in the small intestine is a key factor in improving protein utilization efficiency and production performance. Ruminant small intestine amino acids are mainly derived from microbial protein and rumen undegraded protein. Studies have shown that the amino acids provided by microbial protein alone cannot meet the needs of high-yield ruminants, especially lysine. The focus of research at home and abroad has long been on the improvement of rumen bypass protein. It is believed that insufficient non-degra...
