Safety and efficacy of Natugrain® TS/TS L (endo‐1,4‐beta‐xylanase and endo‐1,4‐beta‐glucanase) as a feed additive for sows
Abstract 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‐b...
