Problems solved by technology

As an essential trace element for humans and animals, inorganic salts of copper are mostly used as animal feed additives at present. Animals must pass through various biological barriers to absorb and utilize the inorganic salts. The absorption rate is low, the addition amount is large, and the biological potency is low. , Most of them pollute the environment after being excreted by feces, and have a destructive effect on the activities of other nutrients (such as vitamins, etc.) in the feed. There are also cases where solid threonine and inorganic copper are used as feed additives together, but the operation process is complicated. And the solubility of solid threonine is relatively difficult

Embodiment 1

[0029] A threonine copper finished product of the present invention is prepared through the following steps: firstly open the nitrogen valve, replace the air in the reactor, and then under the protection of nitrogen, first take 40.55g of threonine and put it into a tank containing 100g of reaction water. Fully stir in the reaction kettle, then drop 42.5g copper sulfate pentahydrate, maintain the pH value of the reaction mixture with 13.48g sodium hydroxide at a temperature of 90°C to 6.8g, react for 2.5 hours under normal pressure, and then the reaction product sent to the concentration tank at 0.25kgf / c m 2 Under the vacuum degree and the concentration temperature of 90°C, concentrate in vacuum for 45 minutes. After the product is viscous, the concentrate is fed into the tray, dried in a flash at a temperature of 120°C, and crushed to prepare threonine. Finished copper.

Abstract

The invention discloses application of a threonine chelate named as copper threonate. The copper threonate can be used as an additive for an animal feed, so that the aims of effectively promoting growth of animals, enhancing resistance of the animals and improving the utilization efficiency of the feed are fulfilled.

Description

[0001] This application is a divisional application, the application number of the original application is 200910043299.8, the application date is May 05, 2009, and the invention name is "copper threonine and its preparation method and application". technical field [0002] The invention relates to a feed additive and a preparation method thereof. In particular, it relates to an amino acid chelate and its preparation method and application. Background technique [0003] 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 can hold water for 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 ac...
