Scientific Opinion on the safety and efficacy of AGal-Pro BL/BL-L (alpha-galactosidase and endo-1,4-beta-glucanase) as a feed additive for laying hens and minor poultry species for laying
The additive AGal-Pro BL/BL-L is a preparation of alpha-galactosidase produced by a genetically modified strain of Saccharomyces cerevisiae and of endo-1,4-beta-glucanase produced by a non-genetically modified strain of Aspergillus niger. The additive is intended for use in laying hens and minor poultry species for laying (e.g. ducks, goose, quail, turkey, etc.). This product is currently authorised for use in chickens for fattening as a zootechnical additive, functional group of digestibility enhancers. Aspects other than the safety and the efficacy for laying hens and minor poultry species for laying have been addressed in previous opinions and therefore the present assessment addresses these aspects for the new target species only. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concludes that AGal-Pro BL/BL-L is safe and efficacious for laying hens at the maximum recommended dose of 100 units of alpha-galactosidase/kg feed and 570 units endo-1,4-beta-glucanase/kg feed equivalent in 100 mg/kg feed. These conclusions are extrapolated to minor poultry species for laying at the maximum recommended dose. The data submitted do not allow any conclusions to be drawn on efficacy at the minimum proposed dose of 50 mg/kg feed.
