2022年2月23日,，據(jù)歐盟食品安全局（EFSA）消息,，應(yīng)歐盟委員會要求，歐盟動物飼料添加劑和產(chǎn)品（FEEDAP）研究小組就尼卡巴嗪（nicarbazin ）作為育肥火雞飼料添加劑的有效性發(fā)表科學(xué)意見,。

經(jīng)過評估,，專家小組得出結(jié)論，在100 mg尼卡巴嗪/kg全價飼料的劑量下,，該添加劑具有有效抗火雞球蟲病的潛力,。

部分原文報道如下：

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 updated its previous conclusions on the efficacy of Coxar? as follows: the two new floor pen studies showed efficacy of nicarbazin from Coxar? reducing the adverse clinical consequences of an Eimeria infection in turkeys. Overall, when considering also the positive floor pen study previously reported and the three positive anticoccidial sensitivity tests, the FEEDAP Panel concludes that Coxar? has the potential to be efficacious against coccidiosis of turkeys for fattening at 100 mg nicarbazin/kg complete feed.
