5. Use of Tiamulin

1) Tiamulin is a relatively new type of antibiotic, which is an animal-specific antibiotic.
2).It has a have special effects on number of Gram-positive bacteria and mycoplasma (Mycoplasma) ,
3).by far, Tiamulin is the most effective antibiotics against the Mycoplasma gallisepticum on the chicken , maintain high concentrations on respiratory tract on which Mycoplasma breeding.
4).Especially have a strong effect against Staphylococcus aureus, Streptococcus, a variety of mycoplasma and some spirochetes .
