As a new generation of environmentally friendly feed, microbial feed additives have been used in relevant research institutions and production units in Beijing, Hebei, Tianjin, Gansu and Ningxia, and have achieved good results. Its main components are lactic acid bacteria, Bacillus subtilis, actinomycetes, yeast and other beneficial bacteria. It is made from fertile soil and cultivated and expanded. It can be used as pig, chicken, cow and duck. And the use of auxiliary feed for fish and shrimp farming.
The basic principle of microbial feed additives: The animal's digestive system, especially the intestines, has hundreds of tens of billions of bacteria that form intestinal flora, which is closely related to animal health. In the intestinal flora, it exerts various nutritional and physiological functions, and also inhibits the defense against infection such as the proliferation of pathogenic bacteria. The occurrence of coliform disease, salmonellosis and Clostridium enteritis in livestock is closely related to the state of intestinal bacteria. Therefore, keeping the balance of the intestinal flora normal is essential for maintaining animal health. It is closely related to the improvement and improvement of various indicators in livestock production.
A microbial feed additive is a microbial product that replaces or balances one or more strains in an animal ecosystem. In a narrow sense, it is a microbial product that stimulates the growth of its own beneficial bacteria and resists the growth of harmful strains.
It contains a large number of beneficial microorganisms such as lactic acid bacteria and yeast. As a feed, it can rapidly multiply after entering the livestock and poultry. On the one hand, it is added to the metabolites of the strains and intestinal toxins, inhibiting the growth of other harmful flora. On the one hand, a normal microbial flora is formed in the host, and the host synthesizes the main vitamins, provides nutrition and prevents the invasion of pathogenic bacteria.
After the microbe enters a micro-ecological system (in livestock and poultry), can it settle there, grow and multiply and become a normal flora to form a stable micro-ecological system that is ecologically balanced by microorganisms, host and environment; It depends on whether the biological and host sides have colonization conditions. In general, livestock and poultry are most likely to accept the influence of external beneficial microorganisms in their early years, accelerate the establishment of normal populations in the body, and contribute to the growth of organisms and the improvement of disease resistance. During the test, we also found that when the chicks were fed with microbial feed additive feed, the effect was the best, and the reason was also here. Therefore, the use time should be mastered when using microbial feed additives. For example, pigs should be used on sows before birth, and chickens should be used at the time of brooding.
