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 OptiPhos PLUS to be used as a feed additive for chickens for fattening, chickens reared for laying, turkeys for fattening, turkeys reared for breeding, minor poultry species for fattening, minor poultry species reared for laying, minor poultry species reared for breeding and ornamental birds. The active substance is 6-phytase produced by a genetically modified strain of . The FEEDAP Panel concludes that the genetic modification of the production strain does not give rise to safety concerns. Based on the tolerance studies provided, the Panel concludes that the additive is safe for the target species under the conditions of use with a wide margin of safety. The additive is not a skin irritant. It is found to be a dermal sensitiser. The FEEDAP Panel cannot conclude on the eye irritation potential of the additive. Owing to the proteinaceous nature of the active substance, the additive is considered a respiratory sensitiser. The FEEDAP Panel concludes that the additive has the potential to be efficacious in increasing the phosphorus utilisation in chickens for fattening at the level of 250 FTU/kg feed. These conclusions can be extended to turkeys for fattening and chickens and turkeys reared for laying/breeding and extrapolated to all minor poultry species and other avian species up to the point of lay.
应欧盟委员会要求,动物饲料添加剂及产品或物质专家小组(FEEDAP)被要求就用于育肥鸡、产蛋鸡、育肥火鸡、种用火鸡、育肥小型家禽、产蛋小型家禽、种用小型家禽和观赏鸟的OptiPhos PLUS作为饲料添加剂发表科学意见。活性物质是由基因改造的[具体菌株名称]生产的6 - 植酸酶。FEEDAP小组得出结论,生产菌株的基因改造不会引发安全问题。基于所提供的耐受性研究,小组得出结论,在使用条件下,该添加剂对目标物种安全,且有很大的安全余量。该添加剂不是皮肤刺激物。经判定它是一种皮肤致敏剂。FEEDAP小组无法就该添加剂的眼刺激潜力得出结论。由于活性物质的蛋白质性质,该添加剂被认为是一种呼吸道致敏剂。FEEDAP小组得出结论,该添加剂在饲料中添加水平为250 FTU/kg时,有潜力提高育肥鸡对磷的利用率。这些结论可扩展到育肥火鸡以及产蛋/种用鸡和火鸡,并可外推至所有小型家禽物种以及直至产蛋阶段的其他禽类物种。
