Amino acid plays an important role in the growth, reproduction and production of animals and is an essential amino acid. Methionine (Met) needs to be converted into L-methionine before it can be further used by animals after being ingested into the body of animals.

Methionine is a sulfur-containing essential amino acid for the animal body and the first limiting amino acid in corn-soybean meal-based diet for poultry. It plays a vital regulatory role in the growth, development and various functions of animals.
The role of methionine in feed
1. Nutritional effects
Methionine can synthesize body proteins in animals and can be quickly converted into cystine to meet the needs of animals.
Provides active methyl groups for the body to synthesize some methyl compounds such as choline, keratin and nucleic acids.
Adding an appropriate amount of methionine to the feed of livestock and poultry ruminants can improve the feed conversion rate and the utilization rate 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
Dietary protein and amino acid levels influence the immune function of animals. Increasing the dietary methionine content will increase the antibody titer, immunoglobulin and lymphocyte transformation rate in the body's serum. At the same time, dietary methionine levels also have an impact on cellular immunity, which can promote the absorption of other nutrients in livestock and poultry ruminants, improve resistance, and reduce mortality.
3. Protect liver
Methionine helps protect the liver during the body's metabolism. If the body consumes too little methionine, urea and non-protein nitrogen in the blood will increase, and fat will easily be deposited in the liver.
4. Detoxification effect
Aflatoxin is a metabolite of Aspergillus aflatoxin, which has the effects of inducing mutations, suppressing immunity and causing cancer. Methionine can combine with mycotoxins in feed and reduce toxicity. Methionine also has an inhibitory effect on mold. When added to feed, it can prevent or control feed nutrients from being decomposed by mold.
5. Reduce the crude protein level of the diet
The level of methionine in the diet will affect the utilization of other amino acids and the performance of production performance. On the premise of ensuring the balance of amino acids, advancing the dietary methionine level can reduce the dietary protein level without affecting production performance. Studies have shown that even if other essential amino acids other than methionine are added to low-protein diets, the weight gain and feed conversion rate of broilers are still significantly lower than those of high-protein diets. Further addition of methionine can eliminate this difference. If the total sulfur-containing amino acids in the diet meet the needs, 18.0% to 18.7% crude protein and 20.4% to 21.5% crude protein have the same effect on broiler production performance and carcass fat deposition.
6. Improve production performance
Methionine can promote the growth of broiler chickens, increase daily weight gain, and reduce feed-to-meat ratio; it can increase egg production, egg weight, and eggshell quality during the peak egg production period and egg production cycle of laying hens. Adding more than 0.6% DLM or 0.68% MHA to the diet of laying hens can also acidify urine, reduce kidney damage caused by calcium, and reduce the incidence of urinary stones. However, excessive acidification of calcium will affect calcium metabolism, thereby affecting egg production, eggshell quality and bone mineralization, causing metabolic acidosis.
7. Used as an acidifier in piglet diet to reduce the acidity of the feed system
The function of the digestive tract of piglets is incomplete and gastric acid secretion is insufficient. When weaning stress occurs, the balance of gastrointestinal microorganisms is destroyed, and Escherichia coli breeds rapidly, eventually leading to diarrhea and reduced production performance of piglets. Acidifiers can increase the activity of digestive enzymes by lowering the pH value of the gastrointestinal tract, changing the suitable living environment for harmful bacteria or directly inhibiting and killing pathogenic bacteria, while promoting the reproduction of beneficial bacteria.
Methionine can buffer the neutralization of gastric acid by high-alkali ingredients in the diet, enhance the acidic environment of the gastrointestinal tract, and increase pepsin. The activity of duodenal trypsin and the activity of beneficial intestinal microorganisms promote the digestion and absorption of nutrients, especially proteins, thereby reducing nutritional diarrhea in piglets, especially early adoptive piglets, and promoting their growth.
8. Bacteriostatic and sterilizing
Adding methionine to feed can inhibit the production of various mycotoxins. Methionine can bind to mycotoxins in feed, making them less toxic. After being added to the feed, it can prevent or control the decomposition of mold nutrients in the feed. At the same time, the body's decomposition of mycotoxins is enhanced, so that production performance can be fully utilized.
Adding methionine to feed is closely related to animal health and production, so its effective and low-cost use is particularly important. The rational application of different forms of methionine will improve resource utilization, improve animal production performance, and then use nutritional principles to greatly reduce feed costs.
