ConclusionHigh Grade Product


1. Promote growth and improve production performance: Methionine can synthesize body protein in animals, and can quickly convert into cystine to meet the needs of animals; provide active methyl groups for the body to synthesize choline, keratin and nucleic acids, etc. Some methyl compounds; add appropriate amount of methionine to livestock and poultry ruminant feed to improve feed conversion rate and utilization of protein raw materials, thereby increasing benefits. Adding an appropriate amount of methionine to laying hen feed can effectively improve the production performance of laying hens. Promote poultry egg production and improve egg quality.

2. Improve animal immunity: The level of protein and amino acids in the diet affects the immune function of animals. Increase the content of methionine in the diet, and the antibody titer, immunoglobulin and lymphocyte conversion rate in the body's serum will increase. At the same time, the level of dietary methionine also has an impact on cellular immunity. It can promote the absorption of other nutrients in livestock, poultry and ruminants, improve resistance and reduce mortality.

3. Hepatoprotective effect: Methionine is beneficial to protect the liver in the process of body metabolism. If the intake of methionine in the body is too low, the urea and non-protein nitrogen in the blood will increase, and fat will easily be deposited in the liver.

4. Detoxification: Aflatoxin is a metabolite of Aspergillus flavus, which can induce mutation, suppress immunity and cause cancer. Methionine can combine with mycotoxins in feed to reduce toxicity. Methionine also has an inhibitory effect on mold. After being added to feed, it can prevent or control the decomposition of feed nutrients by mold.
