Main Functions and Roles of Lactic Acid Probiotics in Animal Husbandry Part 2
As shown from the previous article, Lactic Acid Probiotics can have various applications in the field of animal husbandry, mainly including improving intestinal environment, increasing feed utilization, promoting growth, enhancing immunity, reducing disease incidence, and improving the quality of meat, eggs, and milk. This article will continue to delve into the effects that Lactic Acid Probiotics creates to impact the overall health of the animal being farmed.
Promoting growth and digestion: Lactic Acid Probiotics can promote the digestion and absorption of nutrients, breaking down lactose molecules into small monosaccharides such as glucose and galactose, making them more easily absorbed by animal bodies. In addition, the metabolic products of Lactic Acid Probiotics include various enzymes such as protease, amylase, glucosidase, etc., which can degrade large molecule nutrients in feed into small peptides, glucose, etc., promoting digestion and absorption. Lactic Acid Probiotics can also break down lignin and cellulose, improving the nutritional value of feed.
Boosting immunity: Lactic Acid Probiotics have the ability to engulf cells and colonize in the intestine, forming a natural immune system. They can also induce the production of interferon, accelerate cell division, form antibodies, and enhance cell immunity and disease resistance.Lactic Acid Probiotics have significant antibacterial effects and can effectively inhibit the growth of some spoilage bacteria, improving gastrointestinal diseases such as diarrhea, constipation, and enteritis.
Regulating the balance of gastrointestinal microbiota: Lactic Acid Probiotics are the dominant microbiota in animal intestines, which can inhibit the growth of harmful bacteria and maintain the dynamic balance of gut microbiota. The various organic acids and antibacterial substances produced by lactic acid bacteria metabolism can inhibit and reduce the reproduction of harmful bacteria.
Specific application case: In calf breeding, Lactic Acid Probiotics can promote the growth and development of calves, prevent and treat diarrhea. Studies have shown that feeding newborn calves fermented milk containing lactic acid bacteria for 30 days can significantly prolong their rumination time, promote rumen development and premature weaning. In addition, it can also improve the intestinal health of calves, form developed intestinal villi, and contribute to the development of small intestinal villi. When used in combination with other beneficial probiotics such as Bacillus subtilis and Bacillus licheniformis, the effects can be magnified because of the mutual synergistic effects that the probiotics share.
