Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the efficacy of two technological additives consisting of strains ATCC 53519 and ATCC 55593, respectively. The additives are intended for use with all types of fresh materials and for all animal species at a proposed minimum concentration of 1 × 10 colony forming units (CFU) of ATCC 53519/kg forage or 5 × 10 CFU of ATCC 55593/kg forage. In a previous opinion, the FEEDAP Panel could not conclude on their efficacy since the dry matter content of the ensiled materials at the end of the experiments was not corrected for volatiles, which led to an unreliable estimation of the dry matter loss, and the lack of positive effects on any of the other parameters. The supplementary information submitted by the applicant included updated data on the pH values and the dry matter loss corrected for volatiles. However, the estimation of the dry matter loss corrected for volatiles was wrongly calculated and thus, was not considered for the assessment of the efficacy of the additive. Considering the lack of effect on any other fermentation parameter, the Panel could not conclude on the efficacy of the additive to improve the production of silage under the proposed conditions of use.
应欧盟委员会的要求，欧洲食品安全局（EFSA）被要求就分别由ATCC 53519菌株和ATCC 55593菌株组成的两种技术添加剂的功效发表科学意见。这些添加剂拟用于所有类型的新鲜原料，并用于所有动物品种，建议的最低浓度为每千克草料1×10菌落形成单位（CFU）的ATCC 53519或每千克草料5×10 CFU的ATCC 55593。在先前的一份意见中，饲料添加剂和产品授权小组无法就其功效得出结论，因为实验结束时青贮饲料的干物质含量未针对挥发物进行校正，这导致对干物质损失的估计不可靠，并且对任何其他参数均缺乏积极影响。申请人提交的补充信息包括pH值的更新数据以及针对挥发物校正后的干物质损失。然而，针对挥发物校正后的干物质损失估计计算错误，因此未被用于评估添加剂的功效。考虑到对任何其他发酵参数均无影响，该小组无法就添加剂在建议的使用条件下改善青贮饲料生产的功效得出结论。
