L-threonine is an essential amino acid.It'sis a white rhombic system or crystalline powder. No smell, slightly sweet taste.
At present, the relative lack of domestic feed resources, especially the lack of protein feed such as soybean meal and fish meal, has seriously restricted the development of animal husbandry. If threonine is not used in the feed, the regulation of threonine in the feed can only depend on the protein raw materials. The use of threonine can reduce the waste of essential and non-essential amino acids.
With the improvement of people's living standards and the development of aquaculture, threonine as feed amino acid, is widely used to add the piglet feed, swine feed, poultry feed, shrimp feed, eel feed and so on.
