In the animal intestine, Probio-Mix can accurately inhibit the growth and reproduction of pathogenic bacteria, thereby reducing the damage of harmful bacteria to the intestinal mucosa. At the same time, it actively regulates the intestinal microecological environment, promotes the proliferation of beneficial bacteria, enhances the intestinal mucosal barrier function, and improves intestinal health. This not only helps to improve the production performance of poultry and livestock, but also significantly improves feed conversion rate, increases the survival rate of young animals, and brings considerable economic benefits to farmers.
