CORID 9.6% Oral Solution is a coccidiostat specifically labeled for both the treatment and prevention of bovine coccidiosis (bloody scours) caused by Eimeria bovis and Eimeria zuernii in calves.
CORID contains amprolium, a compound that interferes with coccidia’s ability to utilize Vitamin B₁ (thiamine), helping control coccidia populations when administered according to label directions.
CORID may be administered in drinking water or as a drench, making it flexible and easy to use in beef and dairy operations.
Key Features & Benefits

- Suitable for herd-wide use during outbreaks
How CORID Works
CORID resembles Vitamin B₁ but provides no nutritional value.
Coccidia require Vitamin B₁ to grow and reproduce. When coccidia ingest amprolium, they experience a functional thiamine deficiency, leading to starvation and interruption of the coccidia life cycle.
