Recovery of titanium (Ti) in spiked fecal samples from dairy cows consuming a lactation ration, beef steers consuming a finishing ration, and cows grazing native range and containing high (1.049 g/kg), medium (0.450 g/kg), or low (0.150 g/kg) concentrations of Ti as measured using an external calibration curve. The intra- and inter-assay coefficient of variation (CV) measured in the spiked fecal samples
