What is the use of Florfenicol injection in cattle?
Florfenicol Injection is primarily used to treat bovine respiratory diseases such as those caused by bacterial infections such as Mannheimer's disease hemolytica, Pasteurella multocida, and Histophilus somnus. These pathogens commonly cause diseases such as pneumonia, which can seriously affect the health and productivity of cattle in feedlots and other intensive farming systems.
What is the withdrawal period for florfenicol in cattle?
Florfenicol's withdrawal period for cattle varies slightly depending on the route of administration:
- Subcutaneous administration (common in respiratory disease treatment): A withdrawal period of 38 days is generally required before slaughtering cattle treated with products like Resflor Gold, which combines florfenicol with an NSAID for enhanced efficacy in respiratory infections.
- Intramuscular administration: When florfenicol is injected intramuscularly, a withdrawal period of approximately 28 days is necessary before cattle are slaughtered. This longer period allows residues to clear, minimizing the risk of them entering the food supply.
