Amino acids constitute proteins. It can be said that the nutrition of proteins is actually the nutrition of amino acids. Amino acid feeds play a very important role in the life process as protein feeds. Lysine feed and methionine feed are two of them, and they are two very important. This article will detail the specific information of these two amino acid feeds.

Methionine
Lysine
Application
1. Methionine
Methionine is an essential amino acid containing sulfur and is closely related to the metabolism of various sulfur-containing compounds in the living body. In the absence of methionine, it can cause loss of appetite, slow growth or no increase in body weight, kidney enlargement and iron accumulation in the liver, and finally lead to liver necrosis or fibrosis. Methionine can also be detoxified by methylation of toxic substances or drugs by using the methyl group it carries.
2. Lysine
Lysine is a basic essential amino acid. Since the lysine content in cereal foods is very low and is easily destroyed during processing, it is called a first limiting amino acid.
Lysine regulates the metabolic balance of an organism. Lysine provides a structural component for the synthesis of carnitine, which promotes the synthesis of fatty acids in cells. Adding a small amount of lysine to food can stimulate the secretion of pepsin and gastric acid, improve the secretion of gastric juice, and promote appetite and promote the growth and development of animals. Lysine also increases calcium absorption and its accumulation in the body, accelerating bone growth. If lysine is lacking, it will cause insufficient secretion of gastric juice and anorexia, nutritional anemia, resulting in central nervous system obstruction and dysplasia.
3. Application
At present, there are only 20 kinds of amino acids that constitute common animal and plant proteins. The study found that one of these amino acids is an amino acid that the animal itself cannot synthesize or synthesize in an amount that does not meet the needs of the animal and must be supplied by the amino acid feed. We call it an essential amino acid. Some of the essential amino acids in the feed or diet can not meet the needs of animals, and due to the lack of these amino acids, will limit the use of other amino acids in the diet in animals, we call these amino acids as limiting amino acids. The limiting amino acid may be one or several. The lower the ratio of the content of certain amino acids in the feed or diet to the amount required by the animal, the greater the degree of deficiency and the limitation of other amino acids. The stronger, the greater the impact on the nutritional value and utilization of the protein.
The most lacking of the porcine diets based on cereals is the lysine feed, and the chicken is the methionine feed. Therefore, in general, the two are the first limiting amino acids of pigs and chickens, respectively. Due to the large difference in amino acids in natural feeds, amino acid additives can be used to balance or supplement the amino acids required for livestock production, thereby ensuring sufficient quantities and suitable ratios of various amino acids in the compound feed. For this reason, the addition of amino acids has been used as an effective means to improve the utilization of feed proteins, thereby making amino acids the most widely used additive. Lysine and methionine are monomeric amino acids commonly used in compound feeds, and are also monomeric amino acids with economical added benefits.
Methionine feed is not very large in terms of pig feed. But it has a great effect on chicken feed. Methionine feed is the first limiting amino acid in chicken feed. When broiler diets lack methionine, the ability to produce antibodies is reduced. The level of dietary methionine has a very important relationship with the immune performance of chickens.
Lysine feed has an important role in satisfying animal needs, promoting animal growth, improving amino acid balance, improving feed utilization, and saving protein resources in the metabolic process of the body. It is essential for fish and insufficient for plant protein. Amino acid. Adding feed grade lysine to plant feeds can not only replace high-cost fishmeal, but also improve meat quality. For example, adding lysine feed can improve carcass quality and increase lean meat rate. Moreover, because the phosphorus content of plant protein is less than that of fishmeal, it can also reduce the emission of phosphorus in the environment and reduce environmental pollution.
Methionine feed and lysine feed play a pivotal role in different animals. Learn about these two amino acid feeds and make the most of them on your farm so that they can fully play your poultry and livestock on your farm.
