Bacitracin zinc premix is light brown or yellowish brown powder; It smells very bad. Bacitracin zinc is a polypeptide antibiotic, which has bactericidal effect on gram-positive bacteria. Its mechanism is mainly to inhibit the bacterial wall synthesis of bacteria, but also to combine with the cell membrane of sensitive bacteria, damage the integrity of the cell membrane, and cause the outflow of important substances in cells. Effectively inhibit gram-positive bacteria and some gram-negative bacteria; Bacterial resistance to bacitracin is slow, and there is no cross resistance with other antibiotics. Promote the growth of livestock and poultry and improve the feed conversion rate. Bacitracin zinc is hardly absorbed after oral administration, and most of it is excreted with feces within 2 days. Bacitracin zinc has synergistic antibacterial effect with penicillin, streptomycin, neomycin, aureomycin, colistin, etc. This product is incompatible with olaquindox, kitasamycin, virginiamycin and enramycin. It is used for infection of gram-positive bacteria and penicillin resistant staphylococcus.
