CAN RESISTANCE TO COCCIDIAL ORGANISMS DEVELOP WHEN VACCINATIONS ARE USED TO MANAGE COCCIDIOSIS?
A. No. Vaccination enables birds to naturally develop lifelong immunity against coccidia, which helps prevent the development of coccidiosis. No resistance develops. In contrast, in-feed anticoccidials control the development of coccidiosis by minimizing the existing population of coccidia. This is an entirely different approach to coccidiosis control that can and has resulted in the development of resistance to anticoccidials, particularly those used over a long period of time. Q.
