# Efficacy of a feed additive consisting of a copper(II)‐betaine complex for all animal species (Biochem Zusatzstoffe Handels‐ und Produktionsges. mbH)

## TL;DR

This study confirms that a copper(II)-betaine complex is an effective and safe source of copper in animal feed for all species.

## Contribution

The study provides new evidence of the bioavailability and efficacy of copper(II)-betaine complex in chickens for fattening.

## Key findings

- The additive is a bioavailable source of copper for all animal species.
- The FEEDAP Panel confirms the efficacy of the additive as a copper source in feed.
- The additive was previously found safe for animals, consumers, and the environment.

## Abstract

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.
