核心提示:2022年11月8日,据欧盟食品安全局(EFSA)消息,应欧盟委员会要求,欧盟动物饲料添加剂和产品(FEEDAP)研究小组就一种6-植酸酶(6-phytase)作为所有家禽物种和猪饲料添加剂的安全性和有效性发表科学意见。
   食品伙伴网讯  2022年11月8日,据欧盟食品安全局EFSA)消息,应欧盟委员会要求,欧盟动物饲料添加剂和产品(FEEDAP)研究小组就一种6-植酸酶(6-phytase)作为所有家禽物种和猪饲料添加剂的安全性和有效性发表科学意见。
 
  据了解,这种6-植酸酶由里氏木霉CBS 146250产生。经过评估,专家小组认为在拟议的使用条件下,该添加剂对所有家禽物种和所有猪都是安全的。当对于所有生长中的家禽品种和所有猪以500 FTU/千克补充时,以及对于产蛋鸡和其他产蛋鸟以300 FTU/千克补充时,该添加剂在提高磷利用率方面是有效的。部分原文报道如下:
 
  Following a request from the European Commission, the EFSA 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 6-phytase produced by the genetically modified strain Trichoderma reesei CBS 146250 (Axtra® PHY GOLD 30L, Axtra® PHY GOLD 30 T and Axtra® PHY GOLD 65G) as a zootechnical feed additive for all poultry species and all pigs. The FEEDAP Panel concluded that the genetic modification of the production strain does not give rise to safety concerns. based on the no observed adverse effect level identified in a subchronic oral toxicity study in rats, the additive was considered safe for all poultry species and all pigs at the proposed conditions of use. The Panel also concluded that the use of the product as a feed additive does not give rise to concerns for consumers and the environment. Owing to the lack of data obtained with the final formulations, the Panel cannot conclude on the potential of the additive to be irritant to eyes or skin. Due to the proteinaceous nature of the active substance, it is considered a respiratory sensitiser. The panel concludes that the additive is efficacious in increasing the phosphorus utilisation when supplemented at 500 FTU/kg for all growing poultry species and all pigs, and at 300 FTU/kg in laying hens and other laying birds.
