Ceftiofur is a third-generation cephalosporin antibiotic widely used in veterinary medicine to treat bacterial infections in livestock, including cattle, swine, and poultry. It is effective against respiratory diseases, such as bovine respiratory disease in cattle and swine respiratory disease in pigs. Additionally, it is used to treat metritis and mastitis in dairy cows. Ceftiofur is administered via injection, ensuring rapid absorption and distribution in the body. Its broad-spectrum activity makes it a valuable tool in controlling infections caused by susceptible bacteria, helping to improve animal health and productivity. It is also used in some cases to prevent infections during surgical procedures or in high-risk situations.
