MeiHua /FUFENG /EPPEN Brand L-Threonine 98.5%
L-Threonine is an essential amino acid for animals. It can be used for the sedimentation of protein, participate in animal's supersession and maintaining activities to enhance the digestion and immunocompetence of the animal. And it can adjust the balance of the amino acids in feed, enhance the efficiency of feed utilization, and lower the cost of the feed when work with other amino acids.| Items | AJI97 | FCCIV | USP40 |
