Florfenicol is currently a commonly used veterinary antibiotic; it has a broad antibacterial spectrum and a strong antibacterial effect as well as a low the minimum inhibitory concentration (MIC). The antibacterial of florfenicol is about 15-20 times as high as that of chloramphenicol and thiamphenicol.
After administration through feed for 60 minutes, the drug concentration in the tissue can reach peak, which can quickly control the disease with having characteristics such as being safe, non-toxic, no residue, and no risk for triggering aplastic anemia. Therefore, Florfenicol
is quite suitable for large-scale farms application.
