Tips for using lactobacilli mainly include the following aspects:
As a feed additive: Lactobacilli can be used as a feed additive to promote the absorption of nutrients by animals. Lactobacilli can produce a variety of enzymes such as amylase, lipase and protease to decompose macromolecules into small molecules for easy digestion and absorption by animals. In addition, lactobacilli can also synthesize a variety of vitamins (such as niacin, pantothenic acid, folic acid, vitamin B1, B6 and B12) to provide rich nutrition for animals.
Regulating the balance of intestinal flora: Lactobacilli can colonize on the intestinal wall of animals, accelerate the excretion of pathogenic bacteria and inhibit the growth of pathogenic bacteria by lowering the intestinal pH and stimulating intestinal peristalsis, thereby regulating the balance of intestinal flora.
Enhancing immunity: Lactobacilli enhance the immunity of animals through various pathways. They can activate immune cells such as Th2 cells, macrophages, NK cells and B lymphocytes, increase the production of interleukins, and thus improve the immune defense ability of animals.
Adsorption of mycotoxins: Lactic acid bacteria have a strong adsorption capacity for aflatoxin B1, which can form a complex and be excreted from the body, playing a detoxifying role. This adsorption capacity is not affected by temperature, time and the survival state of lactic acid bacteria, but is only proportional to its cell number.
Improving water quality: In aquaculture, lactic acid bacteria can convert harmful organic matter in water into nutrients through oxidation, nitrogen fixation, ammoniation, nitrification and denitrification, purify water quality, increase the dissolved oxygen content of water, and keep water clean.
Precautions for use: Since lactic acid bacteria are sensitive to temperature and salinity, fermented lactic acid bacteria should be used as soon as possible. The suitable growth temperature range is 10 to 30 degrees, and lactic acid bacteria can still survive in a 5% salt environment. In addition, it is not suitable to mix lactic acid bacteria for a long time. It is recommended to alternate lactic acid bacteria and bacillus every other week to avoid excessive acidic substances causing thinning of the intestine.
