    歐盟評估一種內(nèi)切-1,4-β-木聚糖酶作為家禽和豬飼料添加劑的安全性和有效性
    日期:2021-05-08  來源:食品伙伴網(wǎng)
       食品伙伴網(wǎng)訊  2021年4月29日,據(jù)歐盟食品安全局EFSA)消息,應歐盟委員會要求,歐盟動物飼料添加劑和產(chǎn)品(FEEDAP)研究小組就一種內(nèi)切-1,4-β-木聚糖酶(endo‐1,4‐β‐xylanase )作為育肥雞、蛋雞、鴨、育肥火雞、所有小型家禽、斷奶仔豬和育肥豬飼料添加劑的安全性和有效性發(fā)表科學意見。
     
      據(jù)了解,該添加劑是由里氏木霉CBS 143953生產(chǎn)的。部分原文報道如下:
     
      Danisco Xylanase 40000 G/L is the trade name of the feed additive under assessment and contains endo‐1,4‐beta‐xylanase produced by a genetically modified strain of Trichoderma reesei. It is authorised for use in chickens for fattening, laying hens, ducks, turkeys for fattening, all minor poultry species, weaned piglets and pigs for fattening. 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, a reduction of the minimum recommended level in turkeys for fattening and the extension of use to all poultry species (other than ducks) for fattening or reared for laying/breeding and for laying, suckling piglets and minor growing porcine species. 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 use is made. The additive is not irritant to skin but should be considered as a possible eye irritant and, in common with other proteinaceous substances, respiratory sensitiser. There was no need for assessing the efficacy of the additive in the context of the renewal of the authorisation for chickens for fattening, laying hens, ducks, all minor poultry species, weaned piglets and pigs for fattening. The additive has the potential to be efficacious at 625 U/kg complete feed in all poultry species for fattening (including turkeys) or reared for laying/breeding, and for laying and 2,000 U/kg complete feed in suckling piglets and all minor growing porcine species.
