經(jīng)過評估，專家小組得出結(jié)論，該添加劑可作為所有動物物種的有效銅來源。部分原文報道如下：

 

　　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 efficacy of copper(II)-betaine complex as a nutritional feed additive for all species and categories. In a previous opinion, the FEEDAP Panel characterised the feed additive and concluded that it is safe for the target animals, consumers, and the environment when used up to the maximum authorised levels of copper in the diets. With regard to the safety of users, the additive is considered irritant to the eyes and a skin and respiratory sensitiser. In the current submission, the applicant provided a new efficacy study in chickens for fattening to support the efficacy of the additive. The data submitted provided evidence that the additive is a bioavailable source of copper and thus, the FEEDAP Panel concludes that the additive is efficacious as a source of copper for all animal species.
