1.Probiotics: Enterococcus faecalis can form a biofilm in the animal intestine to attach to the animal intestinal mucosa, and develop, grow and reproduce. Enterococcus faecalis is able to soften the fiber in the feed and improve the conversion rate of the feed. Enterococcus faecalis is able to produce a variety of antibacterial substances that have a good inhibitory effect on pathogenic bacteria such as Salmonella, Escherichia coli and Staphylococcus aureus.
2.Microbial action:
(1) The preparation of Enterococcus faecalis into microbial preparations can be directly fed to farmed animals, which is conducive to improving the balance of intestinal microecology and preventing and controlling the disorders of animal intestinal flora.
(2) Decompose protein into small peptides, synthesize B vitamins and other effects.
(3) Enterococcus faecalis can also enhance the activity of macrophiles, promote the immune response of animals, and increase the level of antibodies.
(4) Enterococcus faecalis can form a biological film attached to the animal intestinal mucosa in the animal intestine, and develop, grow and reproduce, which can form a lactic acid bacteria barrier to resist the side effects of foreign bacteria viruses and mycotoxins, and bacillus and yeast are passerby bacteria and do not have this function.
(5) Enterococcus faecalis can decompose part of the protein into amides and amino acids, convert most of the nitrogen-free extract of carbohydrates into L-type lactic acid, which can synthesize L-calcium lactate from calcium and promote the absorption of calcium by farmed animals.
(6) Enterococcus faecalis can also soften the fiber in the feed and improve the conversion rate of the feed.
(7) Enterococcus faecalis can produce a variety of antibacterial substances, which have a good inhibitory effect on common pathogenic bacteria in animals.
3.Species value:The Catalogue of Varieties of Feed Additives (2013) defines Enterococcus faecalis as a strain that can be added to feed. Enterococcus faecalis has a protective barrier effect. Enterococcus faecalis forms a biofilm on intestinal epithelial cells that protect intestinal epithelial cells from harmful substances. Enterococcus faecalis has nutritional effects, Liu Yan (2008) showed that Enterococcus faecalis contains a variety of small peptides, which can promote the absorption of amino acids and residues, and improve the synthesis of tissue proteins. Enterococcus faecalis produces bacteriostatic substances such as bacteriocins. Bacteriocin through specific adsorption on sensitive cell surface receptors, such as the formation of ion channels to cause ion leakage, affect the synthesis of ATP and the transport of specific substances, and finally inhibit the synthesis of macromolecular substances such as proteins and DNA to cause cell death, thereby playing a bacteriostatic and bactericidal role. One of the bacteriocins produced by Enterococcus faecalis is specific and has a narrow antimicrobial spectrum that prevents pathogenic organisms from coming into contact with intestinal mucosal cells. Enterococcus faecalis can also produce bacteriocins with broad-spectrum antibacterial properties, which have a good inhibitory effect on Pseudomona, Salmonella and Shigella. Studies have confirmed that Enterococcus faecalis can effectively inhibit the growth of Listeria and Staphylococcus aureus due to the metabolism of Enterococcus faecalis to produce Volgamycin. Weaned piglets were fed Enterococcus faecalis, and a decrease in the number of Escherichia coli and Staphylococcus aureus was found in their feces.
