Opinion assesses 6-phytase from Aspergillus oryzae for poultry and pig diets, suggesting possible efficacy.
Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the efficacy of 6‐phytase produced by the genetically modified strain Aspergillus oryzae DSM 33737 (HiPhorius™) as a zootechnical feed additive for all poultry, all porcine species and all fin fish. In a previous opinion, the FEEDAP Panel concluded that the additive is safe for the target species, consumers and the environment. The Panel also concluded that the additive is not a skin and eye irritant but should be considered as skin and respiratory sensitiser. The Panel concluded that the additive had the potential to be efficacious as a zootechnical additive when included in the diet of poultry for fattening or reared for laying/breeding, reproductive porcine species and all fin fish. However, due to the lack of sufficient data, the Panel was not in the position to conclude on the efficacy for laying and reproductive poultry and growing porcine species. The applicant provided new trials to support the efficacy of the additive in those target species. Based on the data provided in the previous and current applications, the Panel concluded that the additive has the potential to be efficacious in all poultry and all porcine species.
