Embodiment Construction

[0018] The production method of the amino acid feed additive of the present embodiment, its specific steps are:

[0019] (1) Add 60% ethanolamine solution into the reaction vessel, add 50% concentrated sulfuric acid solution dropwise at 40°C, continue the constant temperature magnetic stirring reaction for 60min after the dropwise addition, and distill under reduced pressure at 160°C to nothing Distillate, cooled to room temperature, added 28% sodium hydroxide solution, stirred to make it evenly mixed, under the condition of 50°C, added carbon disulfide in 3 times at intervals of 30min, continued stirring at constant temperature until there was no reflux, raised the temperature to 80°C, continue the constant temperature magnetic stirring reaction for 50-60min, cool, filter, and wash with water to obtain α-mercaptothiazoline;

[0020] (2) Add α-mercaptothiazoline and 28% sodium hydroxide solution into the reaction vessel, distill and react at atmospheric pressure for 4 hours, a...

Abstract

The invention relates to a making method of an amino acid feed additive. The making method is characterized by comprising the following steps of preparing alpha-mercaptothiazoline, preparing cysteamine hydrochloride through hydrolization of the alpha-mercaptothiazoline; preparing cysteamine chelates; and cladding the cysteamine chelates, methionine, lysine and other addition agents by using gelatin and sodium alginate as wall materials. The amino acid feed additive has the advantages of reducing the somatostatin level of organisms, promoting digestion metabolism of the organisms, improving theimmune function of the organisms, promoting growth, increasing energy digestibility of ration, and increasing feed net energy, and is broad in application scope, low in cost and convenient to use.

Description

technical field [0001] The invention belongs to the field of feed, and in particular relates to a production method of an amino acid feed additive. Background technique [0002] Semi-haloamine, also known as mercaptoethylamine, is a product of cysteine ​​decarboxylation, a component of coenzyme A, and a life-active substance in animals. A large number of studies on rats, pigs, chickens, cattle, sheep and other animals have shown that cysteamine depletes somatostatin, promotes the secretion of growth hormone, and has different degrees of growth-promoting effects on animals. After reasonable addition in feed, it can also increase feed remuneration and improve the quality of Dong body. Cysteamine also has a growth-promoting effect on aquatic animals. However, cysteamine itself is unstable, which affects its application. Contents of the invention [0003] The purpose of the present invention is to provide a production method of the amino acid feed additive for improving matr...
