Problems solved by technology

As an essential trace element for animals, iron is mostly used as an animal feed additive in the form of inorganic salts of iron. Animals must pass through various biological barriers when absorbing and utilizing it. Part of it is excreted through feces, pollutes the environment, and has a destructive effect on active substances such as vitamins in the feed
There is also an operation method of using solid threonine and inorganic iron as a feed additive to supplement the nutrition of threonine, but the operation process is complicated and the solubility of solid threonine is poor

Abstract

The invention discloses a threonine chelate of iron (II)-threonine and the preparation method comprises the following steps: mixing the ferrous sulphate with threonine aqueous solution according to a mole ratio of (0.5-1.1):2 to react at 60-100 DEG C and with a pH value of 4-8 for 0.5-6h under protection of inert gas and obtaining a reaction product; vacuum concentrating or extracting the reaction products with an organic solvent, drying and crushing to obtain the finished product iron (II)-threonine. The iron (II)-threonine of the invention can be used as the animal feed additive so that theaim to effectively promote the growth of the animal, strengthen the resistance of the animal and improve the utilization efficiency of animal feed can be realized.

Description

technical field [0001] The invention relates to a feed additive and a preparation method thereof, in particular to an amino acid chelate compound, a preparation method and application thereof. Background technique [0002] Threonine is an important nutritional enhancer, which can strengthen the nutrition of grains, cakes, dairy products, etc. Threonine, like tryptophan, also has the functions of restoring human fatigue and promoting growth and development. In medicine, because the structure of threonine contains hydroxyl groups, it has a water-holding effect on human skin. After combining with oligosaccharide chains, it can play an important role in protecting cell membranes; threonine can also promote phospholipid synthesis and fatty acid oxidation in the body , and its preparation has medicinal effects such as promoting human growth and anti-fatty liver, and is often used as a component of compound amino acid infusion. At the same time, threonine is also the basic raw ma...
