Effect of marker dosage frequency and spot fecal sampling frequency in the prediction accuracy of fecal output using chromic oxide and titanium dioxide in grazing BON steers.

This study aimed to evaluate the effect of two marker dosage frequencies and two spot fecal sampling frequencies on the variability of fecal output estimation and fecal recovery rate in grazing Blanco Orejinegro (BON) steers with chromium (Cr) or titanium (Ti) as external markers. Four steers (230.5 ± 14.
