It is effective against various Eimeria species, helping to improve feed efficiency and weight gain in young animals. Commonly included in animal feed at low concentrations for prophylactic use. Also shows activity against some protozoal infections in ruminants. Due to its narrow safety margin, precise dosing is critical to avoid toxicity. Not approved for use in animals producing milk for human consumption.
