Abstract Following a request from European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the proposed modification of the terms of the authorisation regarding the formulation of the product Maxiban® G160 (narasin and nicarbazin). The applicant has proposed to modify the concentration of Microtracer‐F‐Red in the additive from the currently authorised 11 g/kg to a range of 4–11 g/kg. Based on data submitted on the composition and the stability, the FEEDAP Panel concluded that the physicochemical properties of the additive were not affected by the proposed modification. Therefore, the assessment of safety and efficacy made for the former formulation with 11 g Microtracer‐F‐Red/kg is still valid for the newly applied formulation.
