Problems solved by technology

[0002] Cysteamine or its salt is a substance that is easily oxidized in the air, so when it is applied to feed additives, it must be coated with other coating materials, otherwise it cannot be popularized and applied on a large scale
Nowadays, various coating methods have emerged, mainly focusing on the exploration of coating materials, but they can really achieve stable coating effects, and the cost is feasible, and can play a real application not much effect

Abstract

The invention relates to a new composition by slowing-releasing envelope with cysteamine or its saline compound. Said composition comprises: A, cysteamine or its saline compound in 1-95 wt %; main materials used for covering in 1-80 wt % which is mainly sodium alginate, polyacrylic resin II, polylactic acid, polyamino acid, corn zein plasm, poly(D.L-Lactide)-poly(ethylene glycol) block copolymer, crosslinked polyvinyl pyrrolidone, hydroxypropylmethylcellulose phtha late, polyvinyl acetate phthalic acid esters, cellulose ethyl ether, and succinic acetate methylcellulose. This invention also relates to process of slowing-releasing envelope on new compound with cysteamine or its saline, and its use as animal feedstuff additive. The strongpoint of said invention is the excellent effect on envelope; the available utilization by animals of envelope materials degraded in the inner body of animals; further, the reached slowing-releasing technique on the combined use of envelope materials which can express the biological value more effectively in inner body of animals.

Description

technical field [0001] The invention belongs to the field of feed additives, in particular to a new cysteamine or its salt slow-release coating composition for livestock and poultry and aquatic feed, and the invention also relates to the cysteamine or its salt slow-release coating The processing technology of the novel composition of the film and its use as an animal feed additive. Animal feed additives are used to regulate the growth of animals including but not limited to pigs, chickens, ducks, cattle, sheep, rabbits, quail and aquatic animals. Background technique [0002] Cysteamine or its salt is a substance that is easily oxidized in the air, so when it is applied to feed additives, it must be coated with other coating materials, otherwise it cannot be popularized and applied on a large scale. Nowadays, various coating methods have emerged, mainly focusing on the exploration of coating materials, but they can really achieve stable coati...
