1. Maintain the balance of flora in animal intestines, respiratory tracts and other cavities that communicate with the outside world
There is a dominant population of microorganisms in the host, which maintains the balance of the flora in the animal's intestinal tract, respiratory tract and other cavities that communicate with the outside world. If it is missing, it means microecological imbalance. If the host's gastrointestinal micro-ecological balance is out of balance, the animal's digestive system will be disordered, growth and development will be hindered, production performance will decline, and even diseases will occur. After feeding microbial feed additives and supplementing beneficial flora, its main components will become new dominant flora, maintain the balance of animal intestinal flora, and make the imbalanced microecology reach a new balance.
2. Biological barrier effect
The intestinal mucosa of healthy animals has a layer of microbial defense barrier to resist the invasion of foreign pathogenic microorganisms. The beneficial bacteria in the microecological preparation compete with the pathogenic microorganisms for the ecological sites and nutrients on the epithelial cells of the intestinal mucosa, thereby inhibiting the growth and reproduction of the pathogenic microorganisms and maintaining the health of the animal body. Microbial defense barriers include chemical barriers and biological barriers. Chemical barrier refers to the metabolites of intestinal flora, such as acetic acid, lactic acid, hydrogen peroxide and bacteriocins and other active substances, which can kill pathogenic microorganisms and prevent them from colonizing in the host. Biological barrier refers to the biofilm-like structure formed by normal flora planted on skin epithelial cells or mucous membranes, preventing the colonization, occupation, growth and reproduction of passing bacteria and foreign pathogenic bacteria.
3. Biological oxygen capture
When the micro-ecological system in the intestinal tract of animals is out of balance, the local concentration of oxygen molecules increases, which will promote the growth and reproduction of pathogenic microorganisms. Feed probiotics contain active aerobic probiotics. The growth and reproduction of a large number of aerobic microorganisms will reduce the local concentration of oxygen molecules, thereby inhibiting the growth of pathogenic microorganisms, restoring the imbalanced micro-ecological balance, antagonizing the invasion of pathogenic microorganisms, and achieving The purpose of preventing and controlling animal diseases.
4. Stimulate the immune system and improve the body's immunity
Feeding probiotics can stimulate the animal body, increase the concentration of immunoglobulin and the activity of macrophages, and enhance the body's humoral immunity and cellular immunity. Studies have shown that when Bacillus subtilis is fed to chicks, it can significantly increase the amount of T and B lymphocytes in the spleen.
5. Produce beneficial metabolites and antibacterial substances
Probiotics such as lactic acid bacteria Enterococcus faecalis will metabolize to produce lactic acid after entering the intestinal tract of animals. Bacillus subtilis and Bacillus licheniformis can produce volatile fatty acids after entering the intestinal tract of the host, reduce the pH value of the intestinal tract, inhibit the growth of pathogenic bacteria, and enhance The protease activity in the intestinal tract is of great help to the growth and development of young livestock and poultry. Some probiotics will produce lactosin, acidophilin, bacitracin and other antibacterial substances during the metabolic process, thereby inhibiting the growth and reproduction of pathogenic bacteria in the intestinal tract of animals.
Summarize:
Bacillus can form endophytic spores with strong stress resistance - spores, which are very convenient for storage and transportation, and have strong resistance to the instantaneous high heat in the process of feed processing and the acidic environment in the stomach of animals; they can secrete a large amount of enzymes , Supplement the endogenous digestive enzyme deficiency in animals and promote digestion. The main strains of Bacillus are Bacillus licheniformis, Bacillus subtilis, Bacillus natto and so on. However, Bacillus, as a transit bacterium, cannot colonize the intestinal tract. Lactic acid bacteria are the probiotics with the earliest application history and the most types. The main types are Lactococcus, Lactobacillus, Bifidobacterium and so on. Some strains such as Enterococcus faecalis, Pediococcus lactis and Clostridium butyricum have the ability to colonize the intestinal tract. At the same time, after yeast and aerobic bacillus enter the digestive tract, they quickly consume oxygen to create an anaerobic environment for probiotics such as lactic acid bacteria and Clostridium butyricum. There are many customers who use Bacillus subtilis, Bacillus licheniformis, or Clostridium butyricum alone, and the effect is often not ideal. Therefore, the effect of using a certain probiotic alone is often not as good as using two or more functional probiotics with different functional directions at the same time. The bacterial effect is more pronounced. Compound probiotic products, such as general-purpose synbiotics for livestock and poultry, can promote fattening of livestock and poultry, reduce feed-to-meat ratio, and effectively improve feed utilization by combining two or more strains of bacteria through optimized compounding, lactic acid bacteria and bacillus , improve the balance of animal intestinal flora, improve the formation of animal manure, and reduce the odor of ammonia nitrogen in the house.
