The role of enzyme feed additives

Directly decompose nutrients and improve feed utilization. A variety of active enzymes can effectively decompose and digest some of the polymers in the feed into nutrients that animals can easily absorb, or into small fragments of nutrients for further digestion by other digestive enzymes. Some macromolecular substances are difficult for animals to decompose and absorb. Therefore, adding enzyme preparations can promote the decomposition and digestion of nutrients in feed, thereby improving feed utilization.

Eliminate anti-nutritional molecules and improve digestive function. There are some non-starch polysaccharides, pectins, phytic acid, and cellulose polymers in plant raw materials. These substances increase the content and viscosity in the digestive tract of animals, and affect the digestion and absorption of effective nutrients by animals. A variety of enzymes in enzyme preparations, especially β-glucanase, pectinase, phytase, and braverinase, can decompose these substances into small molecular substances, thereby reducing the viscosity of substances in the digestive tract and effectively eliminating these resistances. The adverse effects of nutritional factors can improve the digestive performance of animals.
        

Activate the secretion of endogenous enzymes and increase the concentration of decylase. Due to the use of enzyme preparations, more substrates for a variety of enzymes can be provided, thereby activating more secretion of a variety of digestive enzymes in the animal body, increasing the effective content of digestive enzymes, accelerating the digestion and absorption of nutrients, thereby improving feed utilization Rate and accelerate the metabolism of animals, and promote animal growth.
        
Reasonable application of enzyme feed additives:
        
Use enzyme preparation products scientifically. Enzyme products are a type of feed additives that have been widely used in recent years. Now most of the commercial enzyme preparations are composite enzyme preparations, and the actual application is also based on the selection of composite enzyme preparations. The basis for measuring the quality level and effect of enzyme preparations is mainly based on the type, content, activity and stability of the enzyme. Since these indicators are currently difficult to detect and judge in application, special attention should be paid when selecting them. Some large and professional enzyme preparation manufacturers can coat enzyme preparation products and other special treatments, which can improve the activity and stability of enzymes. Therefore, it is best to choose enzyme preparation products with good reputation and widely recognized by people. If conditions permit, it is best to conduct some tests before applying them in large quantities.

It is applied according to animal species and different growth stages. Due to the high degree of specificity and specificity of enzymes, different animal species and different growth stages, the types and quantities of enzymes in animals are not the same. Therefore, suitable enzyme preparations can be selected according to the characteristics of different animals and different growth stages to be effective. To play and improve the effect of enzyme preparations. In the juvenile stage of animals, the development of the digestive system is not perfect, and the secretion of many digestive enzymes is insufficient, which is the ideal stage for the use of enzyme preparations. Generally, enzyme preparations containing a variety of digestive enzymes should be selected, especially enzyme preparations dominated by protease and amylase. The digestive function of animals in adult stage is relatively perfect, and they have good digestion ability for a variety of nutrients. Therefore, it is best to use βˉ glucanase, phytase, pectinase and other anti-nutritional factors that have the effect of eliminating nutrients. Enzyme. Enzyme preparations rich in proteases and brazing enzymes are used in aquatic animal feed. Under normal circumstances, the effect of using enzyme preparations in livestock is better than that in poultry, and it is better when used in the juvenile stage than in the adult stage.


Use enzyme preparations in combination with the raw materials in the feed. The feed formula is mainly corn-soybean meal type, and it is best to use enzyme preparations based on xylanase, pectinase and βˉglucanase; if the raw materials such as wheat, barley, and rice bran are used more, they should be selected. Enzyme preparations based on xylanase and βˉglucan; when the content of rice flour, rice bran and wheat bran in the feed is large, the enzyme preparations based on β-glucanase and vitaminase should be used; while the feed contains more enzyme preparations. When using raw materials with high protein content such as Lai seed meal and sunflower seed meal, it is best to choose enzyme preparations based on cellulase, protease and beta-mannanase.

The interaction of enzyme preparations and other additives. Some experiments and studies have shown that when using enzyme preparations, appropriate addition of some salts such as cobalt oxide, manganese sulfate and copper sulfate can improve the effect of enzyme preparations. Enzyme preparations and antibiotics have no mutual influence and antagonism, and enzyme preparations can be used synergistically with antibiotic growth-promoting additives.
Pay attention to the influence of the production process. The main component of enzyme preparation is active enzyme. Enzyme is a kind of protein, which is sensitive to heat, light, acid, etc. However, due to the influence of crushing, premixing, pelleting and other additives in the production process of feed, the activity of the enzyme may be lost or even denatured. Therefore, the use of enzyme preparations should reduce the impact of the production process on enzyme activity as much as possible, especially the granulation temperature should not exceed 75 ℃ to ensure that the enzyme preparation has a better effect.
