Abstract

A S-type forage additive is an anionic exchange resin containing exchangeable radical of sulfuric acid. It is prepared through anionic exchange between sulfuric acid radicals and anionic exchange resin to carry the sulfuric acid radical by anionic exchange resin.

Description

technical field [0001] The invention relates to a sulfur source feed additive and a preparation method thereof. Background technique [0002] Sulfur is an essential non-metallic element for living organisms. It is distributed in various cells in animals and mainly exists in methionine, cystine and cysteine ​​in the form of organic sulfur. In addition, it is also present in biotin, thiamine, chondroitin sulfate and mucin sulfate in mucopolysaccharides, as well as heparin, coenzyme A, fibrinogen and glutathione. Sulfur is also contained in keratin such as animal coats, hoof horns, and horns. Sulfur exists in the form of sulfate or sulfate in various tissues in the body, including chondroitin, taurocholic acid, heparin and sulfate. [0003] Sulfur participates in the synthesis of rumen microbial bacterial protein; participates in the biosynthesis of keratin; sulfur compounds are activators of certain enzymes (such as dehydrogenase and esterase), and participate in the synthes...
