欧盟评估一种由内切-1,4-β-木聚糖酶、内切-1,3（4）-β-葡聚糖酶和多聚半乳糖醛酸酶组成的添加剂作为断奶仔猪饲料添加剂的授权更新申请

 

　　据了解，添加剂中的内切-1,4-β-木聚糖酶是由里氏木霉MUCL 49755生产的，内切-1,3（4）-β-葡聚糖酶是由里氏木霉MUCL 49754生产的，多聚半乳糖醛酸酶是由斐济曲霉CBS 589.94生产的。

 

　　经过评估，专家小组得出结论，在建议的使用条件下，添加剂对断奶仔猪、消费者和环境是安全的。在授权更新的情况下，无需评估添加剂的功效。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 the feed additive consisting of endo-1,4-beta-xylanase (produced with Trichoderma reesei MUCL 49755), endo-1,3(4)-beta-glucanase (produced with T. reesei MUCL 49754) and polygalacturonase (produced with Aspergillus fijiensis CBS 589.94) (AveMix® 02 CS/ AveMix® 02 CS L) as a zootechnical feed additive for weaned and suckling piglets. The additive is already authorised for use with weaned piglets. This scientific opinion concerns the request for the renewal of the authorisation of the additive for weaned piglets and the extension of use to suckling piglets. The applicant provided evidence that the additive currently in the market complies with the conditions of the authorisation. There was no new evidence that would lead the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) to reconsider its previous conclusions that the additive is safe for weaned piglets, the consumer and the environment under the authorised conditions of use. This conclusion applied also to the new target species (suckling piglets) for which a request for an extension of use was made. The additive in both formulations (powder and liquid) is not irritant to skin or eyes but should be considered a dermal and respiratory sensitiser. There was no need for assessing the efficacy of the additive in the context of the renewal of the authorisation for weaned piglets. The Panel concluded that the additive is efficacious in suckling piglets at 2140 XU, 1230 BGU and 46 PGLU/kg complete feed.
