What are the functions and functions of lysine in feed?


Lysine contains amino acids, essential nutrients for humans and animals. What are the functions of lysine? Lysine can be obtained from everyday food, but it is sometimes not sufficient for the growth of animals. Adding lysine in the process of feeding animals can contribute to the healthy growth of animals. Let's take a look at the effects of lysine in feed:


What are the functions and functions of lysine in feed?


Good quality piglet feed is usually rich in protein, lactose, and sometimes sucrose and glucose. Crystallized lysine from protein or added with reducing sugars (as mentioned above) can combine under suitable humid and hot conditions to form indigestible components. Therefore, most piglet feeds are supplemented with higher doses of lysine to compensate for the expected losses from pelleting and storage. In general, a Maillard reaction occurs when amino acids are heated at a certain amount of humidity to produce a chemical reaction. This involves binding free amino groups (such as those crystalline amino acids, which, unlike other amino acids, have two such groups in lysine) to reducing sugars (such as those derived from lactose and sucrose/dextrose). This "Browning" reaction can occur even at room temperature, but it happens very slowly. However, when the Browning reaction is excessive (for example, in the case of improper granulation) or is not properly controlled (when stored for a long time at high temperature and humidity), the protein quality is bound to be reduced.


At present, taken a large part of the diet in the pig farms are corn, soybean meal diet, corn, soybean meal diet, but the corn and soybean meal contains amino acids can't meet the demand of the pig, and the lack of essential amino acids, protein synthesis pigs decreased, causing a series of the protein metabolism and related enzyme synthesis problem in the body and the main performance for growth retardation, It can even cause metabolic diseases. Therefore, it is necessary to add lysine to the feed.


Lysine can not only improve the utilization rate of feed, but also increase the immune ability and disease resistance of fish in fish culture, which also helps to reduce the risk of farming. In fish culture, lysine has an obvious effect on improving the food intake of fish, mainly because lysine has a significant effect on improving the function of digestive enzymes in the intestinal tract of fish. Digestive enzymes are substances with unique functions in the digestive process, and the digestive capacity of animals is closely related to the activities of digestive enzymes in the digestive tract. In addition, in pig breeding, lysine can also use its own substances to methylate toxic substances or drugs and play a detoxification role.


Overall, lysine can meet the needs of animals, promote the growth of animals, improve the balance of amino acids, improve feed utilization, and save protein resources. The significant protein deposition of methionine allows the same feed to have a significant effect on the weight gain of animals, so that some cost savings can be achieved.
