Animal feeding stuffs. Methods of sampling and analysis. Detection of tylosin, spiramycin and virginiamycin. Thin Layer Chromatography and bioautography has-tracked-changes This document deals with high-power1 Scope The method makes it possible to detect and identify spiramycin, tylosin and virginiamycin in animal feeding stuffs (feed raw materials of mainly plant origin and compound feeds) excluding mineral feeds and premixtures. The limit of detection is about 2 mg kg for spiramycin, 1 mg kg for tylosin and 1 mg kg for virginiamycin. In some milk replacers, it can be slightly higher than 1 mg kg for virginiamycin. Reported limits of detection are
