    核心提示:2023年4月20日,據(jù)歐盟食品安全局(EFSA)消息,應(yīng)歐盟委員會(huì)要求,歐盟動(dòng)物飼料添加劑和產(chǎn)品(FEEDAP)研究小組就一種6-植酸酶(6-phytase)作為育肥豬飼料添加劑的有效性發(fā)表科學(xué)意見。
       食品伙伴網(wǎng)訊  2023年4月20日,據(jù)歐盟食品安全局EFSA)消息,應(yīng)歐盟委員會(huì)要求,歐盟動(dòng)物飼料添加劑和產(chǎn)品(FEEDAP)研究小組就一種6-植酸酶(6-phytase)作為育肥豬飼料添加劑的有效性發(fā)表科學(xué)意見。
     
      據(jù)了解,這種6-植酸酶由Komagataella phaffii CGMCC 12056產(chǎn)生。由于缺乏足夠的數(shù)據(jù),專家小組無法就添加劑對(duì)育肥豬的有效性得出結(jié)論。部分原文報(bào)道如下:
     
      Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the efficacy of 6-phytase produced by the genetically modified strain Komagataella phaffii CGMCC 12056 (APSA PHYTAFEED  20,000 GR/L) as a zootechnical feed additive (functional group: digestibility enhancers) for pigs for fattening at a minimum recommended level of 1,000 U /kg feed. In a previous assessment, three trials were submitted; one of them showed significant improvements on zootechnical parameters supporting the efficacy of the additive. The other two trials evaluating apparent faecal phosphorus digestibility and bone mineralisation, showed no improvements on phosphorus retention in bone and, therefore, the FEEDAP Panel could not conclude on the efficacy of the additive. The applicant submitted two new efficacy studies in pigs for fattening evaluating the animal's zootechnical performance, apparent faecal phosphorus digestibility and bone mineralisation. One of the trials was not considered due to high rates of mortality, culling of animals and medical treatments applied. In the other trial, significant improvements on final body weight and apparent total track phosphorus digestibility were found in the animals that received the phytase at 1,000 U/kg complete feed. Owing to the lack of sufficient data, the FEEDAP Panel could not conclude on the efficacy of the additive in pigs for fattening.
