What are the functions of lysine? Lysine can be obtained through daily food, but sometimes it cannot meet the needs of animal growth. Adding lysine in an appropriate amount during the feeding process of animals is conducive to the healthy growth of animals.
Good quality piglet feeds are generally rich in protein, lactose, and sometimes sucrose and glucose. Lysine from protein or added crystals can combine with reducing sugars under moderate heat and humidity conditions to form indigestible components. Therefore, swine feed lysine supplements are used to compensate for the projected losses during pelleting and storage. Generally speaking, when amino acids are heated under a certain humidity to undergo a chemical reaction, a "Maillard reaction" will occur. This involves binding free amino groups (like those crystalline amino acids, unlike other amino acids, lysine has 2 such groups) to reducing sugars (like those from lactose and sucrose/dextrose). This "browning" reaction can even occur at room temperature, but the reaction rate is very slow. However, when the browning reaction is excessive or poorly controlled, the amount of protein will definitely decrease.
At present, most of the rations in pig farms are corn-soybean meal-based rations and corn-soybean meal-based rations, but the amino acids contained in corn and soybean meal cannot meet the needs of pigs, and lack essential amino acids. The synthesis of protein in pigs This will cause a series of protein metabolism and related enzyme synthesis problems in the body, the most important manifestation is growth retardation and even metabolic diseases. Therefore, it is very necessary to add lysine to the feed.
In fish farming, lysine supplementation can also increase the immunity of fish and improve the disease resistance of fish, which also helps to reduce the risk of farming. In fish farming, lysine has a more obvious effect on increasing the food intake of fish, which is mainly because lysine has a significant effect on improving the function of digestive enzymes in fish intestines, and digestive enzymes have unique functions in the digestion process. The digestive power of animals is closely related to the activity of digestive enzymes in the digestive tract. Moreover, in pig breeding, lysine can also use its own substances to methylate toxic substances or drugs to detoxify.
Overall, lysine supplements can meet the needs of animals, promote animal growth, improve amino acid balance, improve feed utilization, and save protein resources. The significant protein deposition of methionine makes the same feed have obvious effects on animal weight gain, so some farming costs can be saved.
