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 safety and efficacy of Natugrain ® TS / TS L. The additive is a preparation of endo‐1,4‐beta‐xylanase and endo‐1,4‐beta‐glucanase produced by two genetically modified strains of Aspergillus niger, and it is authorised for use in piglets (weaned) and pigs for fattening, poultry species and ornamental birds. The applicant requested the extension of use of the additive to sows at 560 TXU and 250 TGU /kg feed. The FEEDAP Panel concluded that there are no concerns for consumer safety and no risks for the environment are expected from the use of the additive in sows. The additive should be considered a potential respiratory sensitiser for the users. Considering the results from a subchronic oral toxicity study and the tolerance study in lactating sows, the Panel concluded that the additive is safe for sows at the recommended dose. The data submitted to support the efficacy for sows allowed the Panel to conclude that the additive is efficacious in lactating sows, data on gestating sows were not given, and therefore, the Panel could not conclude on the efficacy of the additive in that physiological stage.
