　　Following a request from the European Commission, the Panel on Additives and Products or substances used in Animal Feed (FEEDAP Panel) was asked to deliver a scientific opinion on the efficacy of the coccidiostat nicarbazin (Coxar ®) when used in feed for turkeys for fattening. On the basis of the new data provided, the FEEDAP Panel updat ed its previous co nclusions on the efficacy of Coxar ® as follows: the two new floor pen studies showed efficacy of nicarbazin from Coxar ® reducing the adverse clinical co nsequences of an Eimeria infection in turkeys. Overall, when co nsidering also the positive floor pen study previously reported and the three positive anticoccidial sensitivity tests, the FEEDAP Panel co ncludes that Coxar ® has the potential to be efficacious against coccidiosis of turkeys for fattening at 100 mg nicarbazin/kg complete feed.
