Principles for the use of feed additives in feed

First, the basic feed nutrition is the fundamental of livestock and poultry production DnU China feed industry information network - based on feed, service animal husbandry

Regardless of how the outside world promotes the role of feed additives, it is important to recognize the scientific formulation of the basic feed in livestock and poultry production. The so-called feed additive refers to a small amount or a small amount of substance added during the production, processing and use of the feed, and the amount used in the feed is small but the effect is remarkable. Feed additives are inevitable raw materials used in the modern feed industry. They have obvious effects on strengthening the nutritional value of basic feeds, improving animal production performance, ensuring animal health, saving feed costs, and improving animal product quality. That is to say, any feed additive must play a role in the basic feed mix with reasonable nutrition, and the feed additive is only equivalent to the basic feed. This is just like a chef who cooks a good dish and must have a good base of ingredients, and the condiments can only serve as a icing on the cake.

Second, the use of additives should follow the law of livestock and poultry growth DnU China feed industry information network - based on feed, service animal husbandry

At present, various kinds of growth-promoting additives on the market, such as micro-ecological preparations, enzyme preparations, acidifiers, antioxidants, functional peptides, etc., and even some products made by nanotechnology have their own advantages and promoted in different aspects. Livestock and poultry growth and development. According to the data: each livestock has its own growth characteristics, and each growth stage has its physiological form and nutritional needs. Therefore, the development of feed additives must study the specific growth stage of specific livestock to meet specific physiological conditions. Nutritional needs. Similarly, each feed additive has its optimum feeding stage to perform its maximum function. For example, in addition to being added at an early stage of development, growth-promoting additives should be added at a later stage in order to meet the nutritional needs of poultry and increase production levels during the rapid growth period. In the production of livestock and poultry, any kind of additive can not be used blindly, and must conform to the growth and development rules of livestock and poultry.

Third, we must give full play to the synergy of additives DnU China feed industry information network - based on feed, service animal husbandry

Any kind of additive, its role is limited, unilateral, and not as peculiar as the business advertised. Animals are a balanced system. The digestion and absorption of various nutrients are complementary and mutually influential. It is impossible to isolate a certain component. Although all kinds of additives have certain nutritional effects, any single additive can not meet the growth requirements of livestock and poultry. Different additives can play a synergistic role to promote the digestion and absorption of nutrients. Production practices have proven that complex additives are easier to use and can even achieve 1+1>2 effects. For example, xylanase hydrolyzes xylan in chyme to lower the viscosity of the chyme, allowing proteases and lipases to better interact with the substrate; functional peptides are absorbed and act in vivo to enhance the intestines. It is immune and antioxidant, thus maintaining good intestinal digestion and absorption and promoting the absorption of nutrients.

Fourth, the additive can not fully replace the antibiotic DnU China feed industry information network - based on feed, service animal husbandry

The microecological preparations that are constantly being sizzled by merchants and the media are called green additives by many experts and scholars, and are even considered as one of the substitutes for antibiotics. Due to the current poor control of domestic aquaculture environment, the poultry epidemic is frequent, and the abuse of antibiotics is more, resulting in low immunity of animals. This is the main background for the existence and rapid development of the feed microecological preparation industry. However, studies have shown that the therapeutic effect of microecological preparations is far less than that of antibiotics. It is mainly used for disease prevention. The original intention of antibiotics was to treat diseases, and it is still mainly to treat diseases. In the current environment, microecological preparations can not completely replace antibiotics. Its function is mainly to promote the growth and reproduction of normal microbial flora in the intestinal tract of animals and inhibit the propagation of pathogenic bacteria. Its value lies in regulating intestinal function and promoting digestion of nutrients. Absorption, improve animal immunity to improve animal health and improve feed conversion efficiency. Except for micro-ecological preparations, other single feed additives can not replace antibiotics. Even advanced countries such as the United States allow the use of antibiotics. This shows that the role is great, but these countries have made scientific and rational use, but we have not. DnU China Feed Industry Information Network - based on feed, serving animal husbandry

Five, multi-pronged measures to ensure the health of the body is the most important DnU China feed industry information network - based on feed, service animal husbandry

In livestock and poultry production, no matter what kind of feed and feed additives are used, whether imported or domestically produced, these are not the most important. Guanjian is to maintain the health of the body in order to maximize the performance of poultry production. It is necessary to make comprehensive efforts in terms of rationally formulating feed, strengthening feeding management, and improving the breeding environment. In developed countries, the market share of feed microecological preparations is small, mainly because its breeding environment is better than domestic, animals are healthier, and there is no need to prevent too many diseases. At present, there are certain misunderstandings in the use of domestic feed additives. This is not unrelated to the promotion and promotion of some businesses. Some merchants exaggerate the role of additives and try to persuade farmers to use them. The farmers are not aware of the control. The importance of a small chicken house environment and a large environment for farming has not taken into account the importance of ensuring the health of the poultry body. It has been widely used to promote the use of feed additives. It is not known that this practice is not worth the loss. The organism is an organic system. The role of the internal cause is the main one, that is, the health of the body is the most important. The use of additives and other external factors can only play a role in the treatment of the symptoms. DnU China Feed Industry Information Network - based on feed, serving animal husbandry
