Basic action principle of microbial feed additive

For a long time, the following problems have plagued the livestock breeding and production industry:   1. Intestinal diseases caused by Salmonella, Escherichia coli and other harmful bacteria infection& nbsp; 2. The application of chemicals, especially antibiotics, will damage the quality of livestock and poultry products& nbsp; 3. Environmental pollution and breeding environment deterioration caused by improper treatment of livestock and poultry manure& nbsp; Scientific and technological workers at home and abroad have been trying to find economic and effective solutions. By comprehensively comparing various existing measures, the method of applying microbial agents, which has sprung up at home and abroad in recent years, not only has broad-spectrum and significant efficacy, but also has the advantages of simplicity, low investment, high rate of return, safety and reliability, and no toxic and side effects. It can coordinate and improve economic, social and ecological benefits, is conducive to the establishment of a sustainable social and economic structure, and has a very broad development and application prospect& nbsp; As a new generation of environment-friendly feed, microbial feed additives have been used by relevant scientific research institutions and production units in Beijing, Hebei, Tianjin, Gansu, Ningxia and other places, and achieved good results. Its main ingredients are lactic acid bacteria, Bacillus subtilis, actinomycetes, yeasts and other beneficial bacteria, which are isolated from fertile soil and made by cultivation and propagation. It can be used as auxiliary feed for pig, chicken, cattle, duck, fish, shrimp and other breeding industries& nbsp;< br style="font-family: "sans serif", tahoma, verdana, helvetica; font-size: 12px; white-space: normal;"/> Basic action principle of microbial feed additives:   There are hundreds of species in the digestive system of animals, especially in the intestine, and tens of billions of bacteria form intestinal flora, which is closely related to animal health. Intestinal flora can not only play a variety of nutritional physiological roles, but also inhibit the proliferation of pathogenic bacteria and other defensive effects against infection. Colibacillosis, salmonellosis and Clostridium enteritis of livestock are closely related to the state of intestinal bacteria. Therefore, keeping the balance of intestinal flora normal is essential to maintain animal health. It is closely related to the improvement of various indicators in livestock and poultry production& nbsp; Microbial feed additive is a kind of microbial product that replaces or balances one or more bacterial strains in animal ecosystem. In a narrow sense, it is a microbial product that can stimulate the propagation and growth of its own beneficial bacteria and resist the growth of harmful bacteria& nbsp; It contains a large number of lactic acid bacteria, yeast and other beneficial microorganisms. After entering the livestock and poultry as feed, it can reproduce rapidly. On the one hand, the metabolites of the bacteria are added to neutralize intestinal endotoxin and inhibit the growth of other harmful flora. On the other hand, normal microbial flora is formed in the host to synthesize main vitamins for the host, provide nutrition and prevent the invasion of pathogenic bacteria& nbsp; After entering a micro ecosystem (livestock and poultry), can microorganisms settle there, grow and reproduce and become normal flora to form a stable micro ecosystem with ecological balance among microorganisms, hosts and environment; This depends on whether the organism and the host have the conditions for colonization. Generally speaking, livestock and poultry are most likely to accept the influence of foreign beneficial microorganisms in their infancy, accelerate the establishment of normal populations in the body, and is conducive to the growth of organisms and the improvement of disease resistance. During the experiment, we also found that the effect of microbial feed additive was the best when the young chicks were fed. That is why. Therefore, when using microbial feed additives, we should grasp the use time. For example, pigs should be used for sows before birth, and chickens should be used at the time of brooding.
