Abstract A microbiological assay method is described for the coccidiostat monensin in poultry feeds and prerhixes. Samples are extracted with methanol-water (9 + 1), and interfering substances are removed on an alumina column. Microbiological activity in the effluent is measured with Bacillus subtilis (ATCC 6633). Statistical analysis of data from several different rations prepared as meals and pellets indicate a mean recovery and standard deviation of 94.8 ± 9.7 g monensin/ton from a theoretical potency of 110 g monensin/ton. A mean recovery of 98 ± 7.6 µg/g was obtained from samples prepared by fortifying basal rations with t monensin at 110 µg/g Just before extraction.
