核心提示:2021年3月5日,據(jù)歐盟食品安全局(EFSA)消息,應(yīng)歐盟委員會要求,歐盟動物飼料添加劑和產(chǎn)品(FEEDAP)研究小組就地衣芽孢桿菌DSM 19670生產(chǎn)的絲氨酸蛋白酶(serine protease )作為雞育肥飼料添加劑的安全性和有效性發(fā)表科學意見。
   食品伙伴網(wǎng)訊  2021年3月5日,據(jù)歐盟食品安全局EFSA)消息,應(yīng)歐盟委員會要求,歐盟動物飼料添加劑和產(chǎn)品(FEEDAP)研究小組就地衣芽孢桿菌DSM 19670生產(chǎn)的絲氨酸蛋白酶(serine protease )作為雞育肥飼料添加劑的安全性和有效性發(fā)表科學意見。
 
  經(jīng)過評估,專家小組得出結(jié)論,該添加劑對雞育肥是安全的。在沒有數(shù)據(jù)的情況下,無法得出有關(guān)皮膚致敏潛力的結(jié)論。當添加劑使用水平為15,000 PROT/kg飼料對雞育肥有效。部分原文報道如下:
 
  Ronozyme®ProAct is the trade name of the feed additive under assessment and contains serine protease produced by a genetically modified strain of Bacillus licheniformis. Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety and efficacy of Ronozyme? ProAct when used as a zootechnical additive for chickens for fattening. The additive is available in coated thermotolerant granulated and liquid forms (Ronozyme® ProAct CT/L). The production strain and its recombinant DNA were not detected in an intermediate concentrated product used to produce the final formulations. The final products do not trigger a safety concern with regard to the genetic modification. based on the results obtained in a tolerance study in chickens for fattening and the data from a subchronic oral toxicity study the FEEDAP Panel concluded that the additive is safe for chickens for fattening. The FEEDAP Panel concluded that the use of Ronozyme® ProAct CT/L as a feed additive gives rise to no concern for consumers and for the environment. The additive, in either form, is not an eye irritant but should be considered a skin irritant. In the absence of data, no conclusions on the skin sensitisation potential can be reached. Owing to the proteinaceous nature of the active substance it should be considered a respiratory sensitiser. The FEEDAP Panel also concluded that the additive has the potential to be efficacious at 15,000 PROT/kg compound feed for chickens for fattening.
