Cephalosporins are a class of antibiotics that are commonly used in the poultry industry to treat bacterial infections in birds. They are effective against a wide range of bacteria, including gram-positive and gram-negative bacteria.

Cephalosporins are administered to poultry in various forms, including injections, oral medications, and water additives. They are used to treat a variety of bacterial infections, including respiratory infections, skin infections, and gastrointestinal infections.

However, the use of cephalosporins in poultry has been a topic of controversy in recent years, as there is concern that their widespread use could contribute to the development of antibiotic-resistant bacteria. In response to this concern, the FDA has implemented regulations to limit the use of cephalosporins in poultry, including a ban on the use of certain cephalosporins for growth promotion in poultry.
