Threonine is made up of W. C. Rose, isolated and identified from fibrin hydrolyzed products in 1935, has proved to be the last essential amino acid discovered. It is the second or third restrictive amino acid of livestock and poultry, and it plays an extremely important physiological role in animals. Such as promoting growth and improving immune function; Balance dietary amino acids, so that the ratio of amino acids is closer to the ideal protein, so as to reduce the requirement of livestock and poultry for protein content in feed. The deficiency of threonine can lead to the symptoms of reduced feed intake, stunted growth, decreased feed utilization, and immunosuppression. In recent years, lysine and methionine products have been widely used in feed, and threonine has gradually become a restrictive factor affecting the production performance of animals.
