The main nutritional and physiological functions of lysine are manifested in the following aspects:
1、 Used for the synthesis of body proteins, it is a component that forms skeletal muscle enzyme proteins and certain peptide hormones;
2、 It is one of the ketogenic and gluconic amino acids. When lacking carbohydrates, it can be broken down into glucose or ketone bodies;
4、 Participate in fat metabolism.
As a precursor of carnitine in lipid metabolism, carnitine is a component of mitochondrial membrane lipase that allows long-chain fatty acids to be oxidized through the mitochondrial membrane. Therefore, lysine is not only an essential component for protein synthesis, but also participates in energy metabolism in the body. By adding synthetic lysine to increase the lysine level in the diet, animal growth rate and feed efficiency can be improved. In addition, lysine can also enhance the body's ability to resist stress.

Digestion and utilization rate of lysine
Using digestible or utilizable amino acids to prepare a diet can improve the accuracy and protein utilization efficiency of the diet. The absorption efficiency of D-type and L-type lysine is different. D-lysine can hardly be absorbed and utilized, while L-lysine is the main one with biological activity.

1 The environmental temperature also has a certain impact on the feed intake of livestock and poultry. The lower the environmental temperature, the higher the feed intake, and vice versa. Therefore, under high environmental temperature conditions, the demand for lysine should be increased; Under low environmental temperature conditions, the demand should be reduced. High temperature environments not only inhibit the feeding behavior of livestock and poultry, causing a series of heat stress reactions (such as heat wheezing, respiratory alkalosis, and increased peroxidation in the body), but also lead to a decrease in livestock and poultry production performance and changes in their carcass composition, which may promote nutrient redistribution in livestock and poultry and alter their nutritional needs under heat stress conditions.
21、 Series
Different types and strains of livestock and poultry have different genetic characteristics, including growth rate, physical size, carcass composition, egg production performance, and digestive physiology. Therefore, their lysine requirements are also different. Large strains of livestock and poultry at the same age have higher lysine requirements than small strains at the same age.
2、 Age and Gender
The age and weight of livestock and poultry vary, and their requirements for amino acids also differ. The overall trend is that when expressed in terms of dietary concentration, the requirement for lysine decreases with age and weight; But when expressed in grams of lysine per day, the requirement for lysine increases with age and weight, with a decrease in relative requirement and an increase in absolute requirement. Male and female livestock also have different requirements for lysine.
31、 Dietary energy and protein levels
2、 The content and proportion of non essential amino acids in the diet
3、 Utilization rate of lysine in feed
4. Other nutrients
Mineral elements, vitamins, antibiotics, choline, niacin, etc. in the diet can have a certain impact on the lysine requirements of livestock and poultry. In addition, adding betaine, carnitine, etc. to the diet can also affect the lysine requirements of livestock and poultry.
