What is the amino acid content in feed

Tests have shown that adding lysine to animal diets can improve the efficiency of protein synthesis in animals, relatively reduce the fat content of animals, increase the proportion of lean meat, and improve meat quality.


This article contains the following:

  • Amino acids commonly used in feed

  • Is it enough for us to make enough amino acids for feed?

  • Other nutrients


1.Amino acids commonly used in feed

There are currently only 6 feed-grade amino acids that can be industrially produced in feed: lysine (such as L-lysine hydrochloride); methionine (including DL-methionine, DL-hydroxymethionine, DL-hydroxymethionine Calcium, N-hydroxymethylmethionine); L-tryptophan; L-threonine; isoleucine; L-valine

There are a total of 10 essential amino acids in the animal body (the amino acids that cannot be synthesized in the body or are rarely synthesized to meet the needs, and must be supplied from the feed are called essential amino acids). They are lysine, methionine, threonate, and tryptophan. Acid, isoleucine, leucine, histidine, arginine, phenylalanine, valine. Also note that useful particles of calcium are posing as lysine hydrochloride. The true and false of L-lysine can be completely dissolved in water. It is true, or the match is burned and then lysine is put into the fire and burned. The perfect is true.


2.Is it enough for us to make enough amino acids for feed?

 The answer is not so. Amino acids, as the degradation products of proteins in the digestive tract, will have many factors that affect the metabolism of amino acids, including environmental temperature, genetic factors, age and nutritional factors. Here are three points for nutrition.

Poultry adjusts its feed intake to meet its energy needs. When the dietary energy concentration is high, the feed intake of poultry decreases, and vice versa. And dietary protein concentration will affect the requirements of many essential amino acids. Therefore, dietary protein and amino acid concentrations should be adjusted according to different dietary energy concentrations.

The balance of amino acids in the diet also affects the amino acid requirements of poultry. Deficiency and excess of certain amino acids in the diet can cause a balance between amino acids. For example, a lack of cystine in the diet will increase the need for methionine. Too much lysine significantly reduces the effectiveness of arginine, resulting in a lack of arginine.


3.Other nutrients

Insufficient vitamin B12 and choline in the diet will hinder the use of methionine in the synthesis of protein, thereby increasing the need for methionine in poultry. Numerous studies have confirmed that adding betaine and L-carnitine to the diet can save the methionine requirement.

In recent years, research on the nutrition of amino acids has been deepened to determine the content of available amino acids in feeds and use them as a basis for rations. Many feed manufacturers also introduce products that can utilize amino acid technology, and we are no exception. I hope that the introduction can change everyone's concept of over-emphasis on crude protein, reduce unnecessary waste, and gain more benefits.
