Used in veterinary medicine to treat bacterial infections in animals, particularly in cattle, pigs, and poultry. Effective against respiratory infections, urinary tract infections, and skin infections caused by susceptible bacteria. Commonly administered in farms to control outbreaks of diseases like bovine respiratory disease and swine dysentery. Its broad-spectrum activity makes it valuable for treating infections caused by both Gram-negative and some Gram-positive bacteria. Often chosen for its good tissue penetration and long half-life, allowing for once-daily dosing.
