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 ( AST s). 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.
