The additive Biosprint® contains viable cells of Saccharomyces cerevisiae MUCL 39885 and is authorised as a feed additive in sows, dairy cows, horses, piglets (weaned), cattle for fattening, minor ruminants for fattening and minor ruminants for dairy products. The applicant has requested to extend the use of the additive to cats and dogs at a minimum inclusion level of 7 × 1010 CFU/kg of complete feed. S. cerevisiae is considered by EFSA to have qualified presumption of safety status and consequently is considered safe for the target species. The additive is considered as a potential skin and eye irritant and a skin and respiratory sensitiser. Based on the results on efficacy studies provided, the FEEDAP Panel concludes that Biosprint® is efficacious when used in feeds for dogs. However, the FEEDAP Panel considered that the biological relevance of the magnitude of the effect detected is questionable. Based on the trial available, the FEEDAP Panel was unable to conclude on the efficacy of the additive when administered to cats.
