Zinc is one of the essential trace elements for animal body and is a component of many metalloenzymes and insulin. It is called "life element" because it has a wide range of physiological and biochemical functions in the body. Zinc is a component of various enzymes in livestock and poultry, which plays an important role in the normal growth and development of fur and bone, reproductive function, the development of taste system and the normal function of cardiovascular system. It is an essential element to maintain the growth of fur, skin health and tissue repair. Zinc can also affect the synthesis of DNA and RNA, and participate in the metabolism of nucleic acid and protein. Zinc deficiency, the animal skin is not complete keratinization, appetite loss, embryo development is not complete, reproductive function decline, growth arrest and abnormal metabolism of epithelial cells, and lead to low immune function of livestock and poultry, disease susceptibility to increase, affect the growth and development of livestock and poultry and feed utilization rate.
In traditional feeding, zinc in animal diet is provided in the form of inorganic salt. In recent years, the application of organic zinc and chelated zinc is increasingly widespread. Zinc methionine is the zinc salt of methionine, which is formed by chelating methionine and zinc, and it is a new
Feed Additive, which can be used as a supplement of trace element zinc in animals. Many reports have confirmed that zinc methionine supplementation can improve the growth, reproduction and health status of animals, promote the rapid proliferation of tongue mucosa taste bud cells, regulate appetite, inhibit some harmful bacteria in the intestine, prolong the residence time of food in the digestive tract, improve the secretion function of digestive system and the activity of enzymes in tissue cells. The absorption rate of zinc methionine in animals is 2-4 times that of ordinary inorganic zinc, and methionine itself is also a high-level nutrient. Humans and animals can absorb zinc while absorbing methionine.
