Mechanism of action
Equimolar complex of 4,4'-dinitrocarbanilide (DNC) and 2-hydroxy-4,6-dimethylpyrimidine (HDP). DNC inhibits energy metabolism in coccidia by uncoupling oxidative phosphorylation.
Side effects & warnings
For use in broiler chickens ONLY. Causes mottled yolks and reduced egg production — absolutely contraindicated in layers. Heat stress potentiates toxicity; reduce dose in hot weather.
Species-specific contraindications and adverse-reaction reports for chicken may differ from canine / feline reference data — consult the primary citations listed with each rule.
Other Antiparasitic drugs with chicken dosing
Why a species-specific page? Nicarbazin pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in chicken — the rules above are the citations specific to this species, not generic recommendations.
