What does Bacillus subtilis in the Guts of Ruminants?
Firstly, Bacillus subtilis promotes the digestive function of ruminants. It can produce various enzymes, such as amylase, protease, and lipase, which help break down complex carbohydrates, proteins, fats, and other nutrients in feed, improving the digestibility of feed. In addition, Bacillus subtilis can also produce short chain fatty acids such as acetic acid, propionic acid, and butyric acid, which can lower the pH value in the rumen, maintain the balance of gut microbiota, and prevent digestive diseases.
Secondly, Bacillus subtilis has a significant impact on the immune system of ruminants. It can stimulate the immune system and enhance the resistance of animals. Bacillus subtilis can enhance the immunity of animals and reduce the incidence of infectious diseases by producing immune regulatory substances such as antibacterial peptides and lactic acid. In addition, it can also form a symbiotic relationship with beneficial bacteria in the intestine, jointly maintaining intestinal health and improving animal resistance.
Finally, Bacillus subtilis can also improve the intestinal environment of ruminants. It can reduce the oxygen content in the intestine, creating a suitable living environment for anaerobic bacteria such as lactic acid bacteria and probiotics such as bifidobacteria. Through competitive exclusion, Bacillus subtilis can reduce the colonization of pathogenic bacteria in the intestine and protect the integrity of the intestinal barrier. In addition, the metabolites of Bacillus subtilis, such as vitamins, amino acids, and organic acids, help promote nutrient absorption and improve intestinal health.
