2020年4月21日，据欧盟食品安全局（EFSA）消息，应欧盟委员会要求，欧盟动物饲料添加剂和产品（FEEDAP）研究小组就饲料添加剂Cygro 10G对火鸡育肥的有效性发表科学意见。
据了解，Cygro 10G的活性物质为聚醚类离子载体α-马杜霉素铵（polyether ionophore maduramicin ammonium‐α），作为育肥火鸡饲料的抗球虫剂。由于缺乏显示积极效果的地面围栏研究，专家小组无法得出该添加剂是否对火鸡育肥有效的结论。部分原文报道如下：
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.
