OptiPhos is the trade name of the feed additive under assessment containing 6-phytase produced by a genetically modified strain of . It is authorised for use in chickens for fattening and reared for laying, turkeys for fattening and reared for breeding, other avian species for fattening, laying hens, weaned piglets, pigs for fattening and sows. This scientific opinion concerns the request for the renewal of the authorisation of the additive for the species/categories for which there is an authorisation and the extension of use to breeding hens, turkeys for breeding purposes, ornamental birds, minor pig species for fattening or breeding and suckling piglets for the period when solid feed is given. The applicant provided evidence that the additive currently in the market complies with the conditions of the authorisation. There is no new evidence that would lead the EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) to reconsider previous conclusions that the additive remains safe for the animal species/categories, the consumer and the environment under the authorised conditions of use. This conclusion applies also to the new target species/categories for which a request of extension of use is made. The additive is not irritant to skin or eyes but should be considered a respiratory sensitiser. There was no need for assessing the efficacy of the additive for the authorised species/categories. The additive has the potential to be efficacious at 125 OTU/kg complete feed in all poultry species other than turkeys, ornamental birds, pigs for fattening, sows and minor pig species for fattening or breeding; and in turkeys for fattening, reared for breeding and for breeding purposes, weaned piglets and suckling piglets (for the period when solid feed is given) at 250 OTU/kg feed.
OptiPhos是一种正在评估的饲料添加剂的商品名，该添加剂含有由一种转基因菌株生产的6 - 植酸酶。它被批准用于育肥鸡、产蛋鸡、育肥火鸡、种用火鸡、其他育肥禽类、产蛋母鸡、断奶仔猪、育肥猪和母猪。本科学意见涉及对该添加剂在已获批准的物种/类别中续展授权的申请，以及将其使用范围扩大到种母鸡以及用于繁殖目的的火鸡、观赏鸟、育肥或繁殖用小型猪品种以及在给予固体饲料期间的哺乳仔猪。申请人提供了证据表明市场上现有的添加剂符合授权条件。没有新的证据会导致欧洲食品安全局动物饲料添加剂和产品或物质专家小组（FEEDAP）重新考虑之前的结论，即在授权使用条件下，该添加剂对动物物种/类别、消费者和环境仍然是安全的。这一结论也适用于提出使用范围扩大申请的新目标物种/类别。该添加剂对皮肤和眼睛无刺激性，但应被视为一种呼吸道致敏剂。无需评估该添加剂对已获批准的物种/类别是否有效。除了火鸡、观赏鸟、育肥猪、母猪以及育肥或繁殖用小型猪品种外，该添加剂在所有家禽物种中，添加量为每千克全价饲料125个酶活性单位（OTU）时可能有效；在育肥火鸡、种用火鸡和用于繁殖目的的火鸡、断奶仔猪以及哺乳仔猪（在给予固体饲料期间）中，添加量为每千克饲料250个OTU时可能有效。
