歐盟評估α-半乳糖苷酶和內切-1,4-β-葡聚糖酶作為育肥雞等物種飼料添加劑的授權更新申請

據了解，α-半乳糖苷酶是由釀酒酵母CBS 615.94生產的，內切-1,4-β-葡聚糖酶是由黑曲霉CBS 120604生產的。經過評估，專家小組得出結論，該添加劑在授權使用條件下對所有動物物種、消費者和環境都是安全的。在授權更新的情況下，無需評估添加劑的功效。部分原文報道如下：部分原文報道如下：

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the assessment of the application for renewal of Agal-Pro BL/BL-L?. The additive is a preparation of alpha-galactosidase produced by a genetically modified strain of Saccharomyces cerevisiae (CBS 615.94) and endo-1,4-beta-glucanase produced by a non-genetically modified strain of Aspergillus niger (CBS 120604). It is intended to be used as a zootechnical additive (functional group: digestibility enhancers) in chickens for fattening in its solid and liquid forms (Agal-Pro BL?and Agal-Pro BL-L?), and in minor poultry species for fattening and chickens reared for laying only in its solid form (Agal-Pro BL?). The applicant has provided evidence that the additive currently on the market complies with the existing conditions of authorisation. There is no new evidence that would lead the FEEDAP Panel to reconsider its previous conclusions. Thus, the Panel concludes that the additive remains safe for the target animals, consumers and the environment under the authorised conditions of use. Regarding user safety, the additive is considered an irritant to the skin and eyes and a dermal sensitiser. Due to the proteinaceous nature of the active substances, it should be considered a respiratory sensitiser. There is no need for assessing the efficacy of the additive in the context of the renewal of the authorisation.
