经过评估，在缺乏足够数据的情况下，专家小组无法就添加剂对所有动物物种的功效得出结论。部分原文报道如下：

 

　　Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the efficacy of ferrous lysinate sulfate (Plexomin® L-Fe) for all animal species. The additive has not been previously authorised as a feed additive in the European Union (EU). The safety of the additive for the target species, consumer, user and the environment has already been assessed in previous opinions. However, the efficacy remained inconclusive due to the absence of evidence of the bioavailability of the iron contained in the additive in the trials submitted either with chickens for fattening or with weaned piglets. For the present assessment, the applicant submitted a recalculation of the previous data on weaned piglets, which did not show evidence of bioavailability. Therefore, in the absence of adequate data, the FEEDAP Panel could not conclude on the efficacy of ferrous lysinate sulfate for all animal species.
