　　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 7.370 (VTR-phytase) as a zootechnical feed additive for all pigs and growing poultry species. The additive is intended to be commercialised in two formulations: liquid and powder. In a previous opinion the FEEDAP Panel concluded that the additive is safe for target species, consumers and environment. The FEEDAP Panel deemed that both formulations of the additive are not skin and eyes irritant but should be considered skin and respiratory sensitisers. The FEEDAP Panel concluded that VTR-phytase has potential to be efficacious in laying hens at 1000 U phytase/kg complete feed, and this conclusion was extended to all laying and reproductive poultry. However, due to the lack of sufficient data, the Panel was not in a position to conclude on the efficacy for poultry for fattening or reared for laying/breeding, and in any porcine species. The applicant provided new trials to support the efficacy of the additive on those target species. based on the data provided in the previous and current application, the Panel concluded that the additive has a potential to be efficacious as a zootechnical additive for all poultry for fattening and reared for laying/breeding and reproductive porcine species at 500 U phytase/kg complete feed and all porcine species for fattening and reared for reproduction at 750 U phytase/kg complete feed.
