Research progress of Bacillus subtilis in animal husbandry

1. Biological oxygen capture
Bacillus subtilis is an aerobic bacterium that requires a large amount of oxygen during its growth process. It enters the animal intestine and consumes a large amount of free oxygen
Oxygen, reducing the concentration of oxygen and redox potential in the intestine, is beneficial for the growth of anaerobic bacteria such as lactobacilli and bifidobacteria in the intestine,
Maintain the stability of the gut microbiota, improve animal disease resistance, and reduce the incidence of gastrointestinal diseases.
2. Antagonise pathogenic microorganisms and improve the internal and external ecological environment.
Under the influence of competition, the number of Escherichia coli, Clostridium perfringens, and Salmonella in the intestine is significantly reduced, resulting in a decrease in the number of bacteria in the body
An increase in beneficial bacteria leads to a decrease in potential pathogenic bacteria, an increase in the quantity of excretions and secretions, a decrease in pathogenic microorganisms, and thus purification
Reduce the occurrence of diseases through internal and external environment.
3. Produce multiple nutrients
Bacillus subtilis grows and reproduces in animal intestines, producing various nutrients such as vitamins, amino acids, and organic acids,
Growth promoting factors, etc., are involved in animal metabolism.
4. Produce multiple enzymes to promote digestion and absorption
Bacillus subtilis has strong protease, amylase, and lipase activities, helping to digest and absorb nutrients. At the same time,
Enzymes that degrade complex carbohydrates in feed, such as gelatinase, glucanase, and cellulase, can destroy plant feed
The cell wall of cells releases nutrients from the cells, eliminating anti nutritional factors in feed.
