Application of starch hydrolysis in animal husbandry

Bacillus amyloliquefaciens and its related products have various applications in animal husbandry. The following is a detailed introduction for you:

In terms of feed additives

Improving feed quality:

      Bacillus amyloliquefaciens can produce various enzymes, such as amylase, protease, etc. Starch enzymes can help break down starch components in feed, converting them into sugars that are easier for animals to absorb and utilize; Proteases can act on proteins in feed, degrading some large molecule proteins into small molecule peptides and amino acids, thereby improving the nutritional value and digestibility of feed, allowing animals to obtain more nutrients from the same feed intake. For example, in pig farming, adding feed additives containing Bacillus amyloliquefaciens can significantly improve the digestibility of nutrients in the feed, which can promote the growth rate of pigs.

      It can also degrade anti nutritional factors in feed, such as phytic acid and other components contained in some plant-based feed materials, which can affect animals' absorption of minerals and other nutrients. Bacillus amyloliquefaciens decomposes them by secreting corresponding enzymes, reducing the adverse effects of anti nutritional factors and optimizing feed quality.

      Maintaining the stability and shelf life of feed: Bacillus amyloliquefaciens can competitively inhibit the growth and reproduction of harmful microorganisms such as mold in feed. The growth of mold not only damages the nutritional content of feed, but may also produce mycotoxins, posing a threat to animal health. After adding Bacillus amyloliquefaciens, it can quickly seize ecological sites in the feed storage environment, inhibit the growth of mold, extend the shelf life of feed, and ensure the quality stability of feed during storage and use.

In terms of maintaining intestinal health in animals

Regulating the balance of gut microbiota:

      After entering the animal intestine, Bacillus amyloliquefaciens can inhibit the growth and reproduction of harmful bacteria (such as Escherichia coli, Salmonella, etc.) in the intestine by secreting antibacterial substances such as bacteriocins and lipopeptide antibiotics, reducing the risk of diseases caused by harmful bacteria in the intestine. At the same time, it can itself serve as a beneficial bacterium that colonizes in the intestine, and together with the existing beneficial microorganisms in the intestine (such as bifidobacteria, lactobacilli, etc.), it constructs a good intestinal microbiota environment, promotes the proliferation of beneficial gut microbiota, and maintains the stability and balance of gut microbiota. For example, in chicken farming, the use of Bacillus amyloliquefaciens preparations leads to a relative increase in the number of beneficial bacteria in the intestine and a decrease in the number of harmful bacteria. This significantly improves the intestinal health of chickens and reduces the incidence of intestinal diseases such as diarrhea.

      It can also enhance the intestinal mucosal barrier function by interacting with intestinal epithelial cells. The intestinal mucosal barrier is an important defense line that prevents harmful substances from entering the animal's body. Bacillus amyloliquefaciens can stimulate intestinal epithelial cells to secrete mucus and other substances, enhance the tightness of the barrier, and improve the intestinal defense ability.

      Enhancing animal immunity: Bacillus amyloliquefaciens can activate the innate immune response of animals, stimulate the activity of immune cells (such as macrophages, dendritic cells, etc.), make them secrete more immune factors (such as cytokines, etc.), enhance the body's immune defense ability, enable animals to quickly and effectively initiate immune responses in the face of pathogen invasion, reduce the probability of infection, improve animal health and breeding survival rate. For example, in aquaculture, feeding fish with bait containing Bacillus amyloliquefaciens can improve their immune related indicators and enhance their resistance to common fish diseases.

In terms of improving the breeding environment

      Reduce harmful gas emissions in the breeding environment: During animal breeding, feces and other excreta can produce large amounts of harmful gases such as ammonia and hydrogen sulfide, which not only affect the air quality of the breeding environment, but also have adverse effects on the respiratory health of animals. After adding Bacillus amyloliquefaciens to feed or in aquaculture environments, it can promote the digestion and absorption of nutrients by animals, reduce the content of undigested nutrients in feces, thereby reducing the substrate for harmful gas production from the source, reducing the emission of harmful gases in the aquaculture environment, improving the air environment in the breeding house, and promoting the healthy growth of animals.

      Purification of aquaculture water bodies (for aquaculture): In aquaculture ponds and other water environments, Bacillus amyloliquefaciens can decompose organic pollutants such as residual feed, feces, and animal and plant residues in the water, converting them into inorganic substances such as carbon dioxide and water, reducing chemical oxygen demand (COD), biochemical oxygen demand (BOD) and other indicators in the water, improving water quality, maintaining good dissolved oxygen levels, transparency, etc., providing a suitable living and growth environment for aquatic animals, and reducing the risk of aquatic animal diseases caused by water quality deterioration.

      In summary, Bacillus amyloliquefaciens has positive and important application value in various aspects of animal husbandry, such as improving breeding efficiency, safeguarding animal health, and improving the breeding environment.
