Application
1.Adding L-valine to the diet of lactating sows can improve lactation. Its mechanism is that valine can affect the synthesis of alanine and its muscle release, and the addition of valine in the diet of sows can make the plasma alanine rise to adapt to the demand of mammary tissue for glucose raw materials, so as to improve lactation. Valine is very important for the production and development of mammary glands, and valine is the limiting amino acid in the protein diets of lactating sows, and valine deficiency can reduce the role of lysine, and the addition of lysine to lactating pig diets can improve the protein quality of the diets, but it also results in a valine deficiency, which then affects the sow's milk production and the weight gain of the piglets. Valine will become the first limiting amino acid when the lysine k level is high.
2. Improve the immune function of animal body. L-Valine can promote the transformation of animal skeletal cells into mature T cells. Valine deficiency can make complement C3 and iron transport protein level decrease, will significantly hinder the growth of the thymus and peripheral lymphoid tissue, has been acidic and neutrophilic cell growth for the inhibition. Valine deficiency in weaned piglets results in a decreased ability to synthesize specific antibodies. Chick lacks valine, the antibody response to Newcastle disease virus is reduced.
3. Affect the endocrine level of animals. Studies have shown that the addition of L-valine to the diets of lactating sows and lactating rats can increase the concentration of prolactin and growth hormone in plasma.

Threonine is an amino acid that cannot be synthesized by the animal itself but is very much in demand. It can be used to accurately balance the amino acid composition of the feed to meet the needs of the animal's growth and maintenance, to increase the weight gain and lean meat ratio, and to reduce the feed-to-meat ratio. Therefore, it is very necessary to add threonine to feed.
