Video 3: Evaluating chemicals for coccidiosis control and prevention

Chemicals may be effective when first used, however, all of them have been subject to rapid resistance development. Due to the ease with which coccidia can develop genetic resistance to a chemical’s relatively simple mode of action, coupled with the selection pressure that chemicals provide in giving a resistant coccidia a reproductive advantage over the sensitive coccidia in the broiler facility, it may be months, or even years, before the broiler producer can once again safely return to using the chemical to which resistance has developed.

When evaluating chemicals for coccidiosis control, consider:

  1. Chemicals are generally effective in the short-term, but carry a huge resistance risk
  2. It’s unclear how long resistance persists
  3. Chemicals do not offer broader protection for Intestinal Integrity
