经过评估，专家小组认为在建议的使用条件下该添加剂对目标物种、消费者和环境是安全的。根据所提供的数据，专家小组无法对添加剂的功效做出结论。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 safety and efficacy of a feed additive co nsisting of Quillaja sapo naria powder and Yucca schidigera powder (Magni-Phi ®) for all avian species (to slaughter age/weight, or to the point of lay) and ornamental birds, as a zootechnical additive (digestibility enhancer and other zootechnical additives). The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) co ncluded that the additive is safe for chickens for fattening at the level of 250 mg/kg complete feed with a margin of safety of 20 assuming that the additive co ntains 3.58% of saponins. This co nclusion was extrapolated to all growing poultry species and ornamental birds. The Panel co ncluded that the use of the feed additive in animal nutrition at 250 mg/kg complete feed is of no co ncern for the safety for the co nsumer and the environment. The Panel also co ncluded that the additive is not irritant to skin, but irritant to the eyes and to the respiratory system. Due to the lack of data, the FEEDAP Panel could not co nclude on the skin sensitisation potential of the additive. The FEEDAP Panel was not in the position to co nclude on the efficacy of the additive for all poultry species and ornamental birds.
