Technical Field

The invention relates to application of cysteamine magnesium as an animal feed additive, and belongs to the technical field of animal feeds.

Background

Cysteamine, also known as mercaptoethylamine, is a decarboxylated product of cysteine, and coenzyme a, a component of animal life active substances. Cysteamine itself is unstable and easily oxidized and damaged in the air, and its hydrochloride is chemically stable, but cysteamine hydrochloride has the disadvantages of easy moisture absorption and poor palatability. Cysteamine can exhaust somatostatin, promote the secretion of growth hormone, increase the level of growth hormone, and promote the growth of animals in different degrees. After the feed is reasonably added, the feed reward can be improved, and the carcass quality is improved.

Magnesium is an important trace element necessary for animals, and the biochemical reactions of most nutrients in organisms are participated in by magnesium, and the magnesium is an activating factor of more than three hundred enzymes in the organisms or directly participated in the composition of the enzymes, and plays an important role in immunity, oxidation resistance, stress resistance and the like of the organisms. Magnesium can reduce stress response of animals, and magnesium can reduce the content of cortisol and catecholamine in blood plasma by adding magnesium under stress state such as transportation and slaughtering, thereby reducing stress effect. The addition of magnesium can increase initial (40 min after slaughter) pH and 24 hr after slaughter of pork, and reduce occurrence of PSE pork (commonly called pork in water). Meanwhile, the addition of magnesium can improve the water retention rate of muscles, the meat quality and the tenderness and improve the meat quality.

However, at present, there is no report on the combination of cysteamine and magnesium as an animal feed additive.
