食品伙伴網訊  2020年4月21日，據歐盟食品安全局（EFSA）消息，應歐盟委員會要求，歐盟動物飼料添加劑和產品（FEEDAP）研究小組就飼料添加劑Cygro 10G對火雞育肥的有效性發(fā)表科學意見。

 

　　據了解，Cygro 10G的活性物質為聚醚類離子載體α-馬杜霉素銨（polyether ionophore maduramicin ammonium‐α），作為育肥火雞飼料的抗球蟲劑。由于缺乏顯示積極效果的地面圍欄研究，專家小組無法得出該添加劑是否對火雞育肥有效的結論。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） was asked to deliver a scientific opinion on the efficacy of Cygro 10G. The active substance of Cygro 10G is the polyether ionophore maduramicin ammonium‐α， a coccidiostat intended to be used in feed for turkeys for fattening. In a former opinion, the FEEDAP Panel concluded that the efficacy of Cygro 10G in turkeys for fattening had not been sufficiently demonstrated. In the present submission, new efficacy studies have been provided by the applicant. A positive effect of Cygro 10G in preventing coccidiosis in turkeys was shown in three anticoccidial sensitivity tests （ASTs）。 However, owing to the lack of floor pen studies showing a positive effect, the FEEDAP Panel is not in the position to conclude on the efficacy of Cygro 10G for turkeys for fattening.
