Description
An EFSA panel gives a scientific opinion on a pig feed additive in this 2026 Europe PMC paper. The additive supplies the enzyme endo-1,4-beta-xylanase, made by a yeast strain, and is sold to improve digestibility in feed for all pig species. A prior opinion had found the production strain suitable for a safety shortcut approach and the additive safe for consumers and the environment.
Open questions remained on safety for gestating sows and on efficacy. Using a no-effect dose from a rat study, the panel judged the additive safe at the proposed minimum levels for the target animals. Skin and eye effects and sensitization findings from the earlier review are also summarized.
