欧盟评估嗜酸乳杆菌CECT 4529作为所有家禽种类和所有观赏鸟类饲料添加剂的安全性和有效性

 　　  2022年3月4日，应欧盟委员会要求，欧盟动物饲料添加剂和产品（FEEDAP）研究小组就嗜酸乳杆菌（Lactobacillus acidophilus）CECT 4529作为所有家禽种类和所有观赏鸟类饲料添加剂的安全性和有效性发布科学意见。 
　　经过评估，专家小组认为该添加剂对目标物种、消费者和环境是安全的。当该添加剂以1×10⁹ CFU/kg全价饲料或5×10⁸ CFU/L饮用水使用时，有可能有效改善所有家禽种类和观赏鸟类的产蛋或生长性能。部分原文报道如下：
 
　　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 the feed additive consisting of Lactobacillus acidophilus CECT 4529 (tradename: Lactobacillus acidophilus D2/CSL) when used as a zootechnical additive for all poultry species and categories and all ornamental birds. The additive is authorised for use in laying hens, chickens for fattening, cats and dogs. With this application, the company requested a new authorisation for use in feed and water for drinking for all poultry species and categories and ornamental birds. The Panel concluded that Lactobacillus acidophilus D2/CSL is presumed safe for the target species, consumers and the environment. As in previous opinions, the Panel also concluded that it is considered an eye/skin irritant and a skin/respiratory sensitiser. Lactobacillus acidophilus D2/CSL when supplemented at 1 × 10⁹ CFU/kg complete feed or 5 × 10⁸ CFU/L water for drinking has the potential to be efficacious in to improving either laying or growing performance in all poultry species/categories and ornamental birds.
