Description
What it is. L-arginine is an amino acid obtained by fermentation from Escherichia coli (strain CCTCC M 20231961). The additive is presented in solid form, containing at least 98.5% L-arginine on a dry matter basis.
What it is for. This amino acid is used as a nutritional additive to balance essential amino acid supply in the diet, complementing or partially replacing protein sources. It is authorised for all animal species, in compound feed as well as in premixtures. The additive may also be administered via drinking water.
Points to watch. Storage conditions as well as stability under heat treatment and in drinking water must be specified in the instructions for use of the additive and premixtures. Determination of arginine content relies on ion-exchange chromatography methods defined by the regulation.
