Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the efficacy of 6‐phytase produced by Komagataella phaffii CGMCC 7.19 (Nutrase P) as a zootechnical feed additive for chickens for fattening, other poultry for fattening or reared for laying and ornamental birds. In a previous opinion, the FEEDAP Panel concluded on the efficacy of Nutrase P for the target species at the level of 1,500 phytase units (FTU)/kg but could not conclude at the minimum recommended use level of 500 FTU/kg complete feed. The applicant has provided supplementary information, consisting in the statistical re‐analysis of the long‐term study assessed in the original opinion, in order to support the efficacy of the additive at the minimum recommended level of 500 FTU/kg complete feed. Considering the previously submitted studies and the re‐analysis of the long‐term study, the Panel concluded that the additive has a potential to be efficacious for chickens for fattening, other poultry for fattening or reared for laying and ornamental birds under the proposed conditions of use.
