Safety and efficacy of Biosaf Sc 47 ( Saccharomyces cerevisiae) as feed additive for pigs for fattening

Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the use of Biosaf Sc 47, a preparation consisting of the yeast Saccharomyces cerevisiae, in pigs for fattening. This additive is already authorised for use in cattle for fattening, dairy cows, rabbits for fattening, sows, piglets, lambs for fattening, horses, dairy goats and dairy sheep. The applicant is now asking for authorisation to use the additive in feed for pigs for fattening at a dose range of 1.25 x 109 - 1 x 1010 CFU kg-1 complete feed. The FEEDAP Panel considers that the safety of this organism for the consumer, the user and the environment has already been established and would not be changed by the proposed extension of use. Consequently, in the present opinion only the safety and efficacy of the additive for the proposed additional target species are considered. The efficacy of the product in pigs for fattening has been demonstrated at the lowest recommended dose in three studies, in which significant improvements were seen in performance parameters. In all three studies daily weight gain was significantly improved, and in two of the studies there was a significant improvement of feed to gain ratio. Since the product was shown to be safe for weaned piglets, the FEEDAP Panel considers that safety for pigs for fattening can be assumed.
