Florfenicol is a synthetic monofluorine derivative of methylsulfonamycin, a broad-spectrum antimicrobial agent of the chloramphenicol class for veterinary use.
● livestock: Florfenicol used to prevent and control asthma, infectious pleuropneumonia, atrophic rhinitis, swine pneumonia, streptococcal disease, etc. caused by respiratory distress, body temperature, cough, choking, reduced food intake, wasting, etc. has a very strong effect on E. coli, etc. caused by piglets yellow and white dysentery, enteritis, hemorrhagic dysentery, edema disease, etc. effective.
● poultry: for the prevention and control of cholera, white diarrhea in chicks, diarrhea, stubborn diarrhea, yellow, white and green stool, watery stool, dysentery, intestinal mucosa dotted or diffuse hemorrhage, umbilicus, packaged heart, packaged liver, chronic respiratory disease caused by bacteria, mycoplasma, infectious rhinitis, cloudy air sacs, cough, tracheal croup, respiratory difficulties, etc. caused by E. coli, Salmonella, Pasteurella.
