It can maintain the balance of gastrointestinal flora of animals and inhibit the growth of harmful bacteria, so that the micro-ecology of animals can reach a good balance. While the animals are eating, they supplement the beneficial microorganisms, the beneficial microorganisms multiply, and the neutral microorganisms will help the beneficial microorganisms. In this case, the harmful microorganisms will be well suppressed and the balance of the animal's intestinal micro-ecology will be maintained. . Microbial secretion of hormones, as well as endogenous antibiotics, can improve the immunity of animal areas and prevent disease control. BUIK system produces organic acids after eating microbial beneficial bacteria. These organic acids can reduce the pH value in the digestive tract of animals, thereby inhibiting the reproduction of many harmful substances, improving the immunity of animals and improving the ability of disease resistance, thus reducing the use of antibiotics. The meat quality of the animal and the egg quality of the egg are greatly improved.
