L-threonine is an essential amino acid. Threonine is mainly used in medicine, chemical reagents, food fortifiers, feed additives, etc. Threonine is a white orthorhombic crystal system or crystalline powder.

If threonine is not used in feed, the regulation of threonine in 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. Use protein raw materials instead of The result of using threonine to adjust the amino acid balance is that the amino acid balance of the feed cannot be improved as much as possible, the waste of a large amount of essential amino acids cannot be further reduced, and the formula cost of the feed cannot be further reduced. It can be said that threonine is a barrier that must be overcome to improve amino acid balance and is a bottleneck problem that all formulators cannot avoid.
