经过评估，专家小组认为该添加剂有可能提高用于育肥牛、小型反刍动物和用于肉类生产的骆驼科动物的性能，但无法就该添加剂在拟定使用条件下对奶牛或其他反刍动物的功效做出结论。部分原文报道如下：

 

　　Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the re-evaluation of the authorisation of the feed additive containing Saccharomyces cerevisae CNCM I-1077 (Levucell® SC) as a zootechnical additive for ruminants. The additive is already authorised for use in dairy sheep and dairy goats, lambs and horses, calves, all minor ruminant species (for rearing) other than lambs and camelids (for rearing) and dairy cows. The additive is intended for use in complete feed for dairy cows, minor ruminant species for milk production and all camelids at the minimum dose of 4 × 10⁸ CFU/kg and for cattle for fattening and minor ruminant species for fattening at the minimum dose of 5 × 10⁸ CFU/kg. In a previous opinion, the FEEDAP Panel concluded that the additive has a potential to improve the performance of cattle raised for fattening, minor ruminant species and camelids raised for meat production but could not conclude on the efficacy of Levucell® SC for dairy cows or extrapolate to minor dairy ruminant species or dairy camelids. The applicant has provided supplementary information to support efficacy of the additive in dairy cows. based on the data provided, the FEEDAP Panel is not in the position to conclude on the efficacy of the additive for dairy cows or other dairy ruminants under the proposed conditions of use.
