Identification of medicinal additives in animal feedingstuffs by high-performance liquid chromatography.
A method is described for the detection of 25 drugs used as prophylactics or as growth promoters in commercial animal feedingstuffs. The sample was extracted with aqueous acetonitrile, the co-extractives were removed with a silica cartridge and the eluate was examined by high-performance liquid chromatography, using two columns and five mobile phases. Thirteen animal ++feedingstuffs containing different combinations of drugs were prepared and used to test the method.
