Description:
1.Isolation and identification of Threonine from the fiber protein hydrolyzate by W. C. Rose in 1935, has proved that it was the last essential amino acids. It is extremely important physiological role in animals, because it is the second or third limiting amino acids for livestock. Such as promoting growth, enhance immune function, etc. Balancing the dietary amino acids to make the ratio of close to the ideal protein, and reducing the protein content of livestock feed requirements. Lacking of threonine, may lead to reduce feed intake, growth retardation, decrease feed efficiency, and suppress immune function and other symptoms;
2.In recent years, lysine, methionine synthesis product has widely used in feed, threonine become the limiting factor affected animal performance gradually. Further study of threonine could help to the livestock and poultry production effectively.
3.Threonine cannot synthesize by animals, however, it is an essential amino acids for them to balance the composition of amino acids precisely to meet the need to animal growth, improve weight and lean meat, reduce the feed conversion.
