What is the role of coccidiostats in animal feed?

• A. To control coccidia parasites
• B. To promote growth
• C. To reduce palatability
• D. To increase fiber

Answer: (A)

The main idea is that coccidiostats are added to feed to curb coccidia parasites in the gut. Coccidia can cause coccidiosis, which damages the intestinal lining, lowers feed efficiency, and reduces weight gain. Coccidiostats work by inhibiting the development or replication of these parasites, lowering their numbers and the associated illness. They’re commonly used in feeds for species at risk, especially poultry and young ruminants, often as a preventive measure or as part of a rotation program to slow resistance. Their effect is indirect—healthier intestines can improve growth and feed conversion, but the primary role is parasite control, not increasing fiber or palatability.
