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.
Appearance:White crystals or crystalline powder; slightly sweet taste.
Prorerty:Very soluble in formic acid, soluble in water; practically insoluble in ethanol and ether.

As a feed additive, L-threonine is a powerful tool helping improve feed quality and reduce feed costs for feed producers. L-Threonine is extensively added to piglet feed, pig feed, chicken feed, shrimp feed and eel feed in conjunction with lysine generally. L-Threonine plays its role in many ways like assisting balance building of amino acids to accelerate growth, improving meat quality, gaining weight and leaning meat percentage, lowing feed conversion ratio, sharpening nutritional value of feedstuff having a poor digestibility of amino acid, helping conserve proteins resources and reduce the cost of feedstuff via cutting down proteins to be added in feed, lessening nitrogen expelled out in livestock manure, urine and concentration as well as its release rate in livestock and poultry sheds, and contributing to consolidate young animals' immune system to resist disease.
