L-Threonine

L-Threonine amino acid is usually the second or third limiting amino acid in pig feed and the third or fourth limiting amino acid in poultry feed. With the wide application of lysine and methionine synthetic products in compound feed, it has gradually become the main limiting factor affecting the production performance of livestock and poultry, especially when lysine is added to low-protein diets, threonine becomes the first limiting amino acid for pigs growth.

If we do not use threonine in the feed, the regulation of threonine in the feed can only rely on protein raw materials, and protein raw materials contain not only threonine, but also other essential and non-essential amino acids, using protein raw materials As a result of not using threonine to adjust the balance of amino acids, the balance of amino acids in the feed cannot be improved more, and the waste of a large amount of essential amino acids cannot be reduced, resulting in the failure to reduce the formulation cost of the feed. Therefore, threonine is a hurdle that must be crossed to improve the balance of amino acids, and it is a bottleneck problem that all formulators cannot avoid.

The advantage of using L-threonine is that it can reduce the waste of essential and non-essential amino acids to a certain extent, or reduce the crude protein level of the feed. Its reason is the same as that of using lysine hydrochloride. Crude protein levels can be reasonably reduced by using crystalline amino acids and animal performance may be greatly improved.
