Safety and efficacy of a feed additive consisting of endo‐β‐1,4‐xylanase produced by Komagataella phaffii CGMCC 7.371 (VTR‐xylanase) for all avian species, piglets (suckling and weaned) and minor growing porcine species (Victory Enzymes GmbH)

Following a request from the European Commission, the EFSA 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 endo‐β‐1,4‐xylanase (VTR‐xylanase) as a zootechnical feed additive for all avian species, piglets (suckling and weaned) and minor growing porcine species. VTR‐xylanase is available in a powder and a liquid form and is produced by a genetically modified strain of Komagataella phaffii (CGMCC 7.371). The genetic modification of the production strain does not give rise to safety concerns. Viable cells of the production strain and its DNA were not detected in the final products. The additive does not pose any safety concern regarding the production strain. VTR xylanase (powder/liquid) produced by Komagataella phaffii CGMCC 7.371 is safe for all avian species, piglets and minor growing porcine species at the proposed conditions of use. The use of both forms of the additive under assessment in animal nutrition under the proposed conditions of use raises no safety concerns for consumers or for the environment. The liquid and powder formulations of VTR‐xylanase are non‐irritant to eyes but should be considered skin sensitisers. No conclusions can be drawn on the potential of the final formulations of the additive to be irritant to skin. Due to the proteinaceous nature of the active substance, the additive is a respiratory sensitiser. The additive has the potential to be efficacious in all laying birds and piglets (suckling and weaned) from all Suidae at 2,000 U/kg and in all other avian species/categories at 1,000 U/kg feed.
