欧盟评估粪肠球菌53519和粪肠球菌55593作为所有动物饲料添加剂的功效

 

　　经过评估，专家小组无法对添加剂在建议使用条件下的功效做出结论。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 efficacy of two technological additives to improve ensiling of forages consisting of Enterococcus faecium strains ATCC 53519 and ATCC 55593, respectively, for all animal species. The additives are intended for use with all forages and for all animal species at a proposed minimum concentration of 1 × 10⁷ colony forming units (CFU) of E. faecium ATCC 53519/kg forage or 5 × 10⁶ CFU of E. faecium ATCC 55593/kg forage, respectively. In a previous opinion, the FEEDAP Panel could not conclude on their efficacy owing to the lack of sufficient evidence for an improvement on the nutrient preservation during the ensiling process. The new data submitted by the applicant as supplementary information provided not enough weight of evidence on the effects of the additives on the ensiling of easy, moderately difficult and difficult to ensile material, and therefore, the FEEDAP Panel is not in the position to conclude on the efficacy of the additive under the proposed conditions of use.
