Excretion of Chromic Oxide Administered in Paper to Steers Fed Prairie Hay1

A. B. Nelson and G. R. Green2

New Mexico State University, Las Cruces

Abstract

Recovery of chromic oxide administered daily in the form of impregnated paper to steers fed prairie hay was near 100% by the third day after initial administration and continued near this level for a 9-day period, with an average recovery of 103%. Differences among steers and days were not significant. When fecal samples were collected every 2 hr., differences among sampling times were not significant.

The recovery of chromic oxide when the indicator was administered every other day was 98% for days beginning 11 hr. after administration and 76% for alternate days. When fecal samples were collected from each steer every 2 hr., differences among sampling times were significant (P<.01). When fecal grab samples were collected only twice daily from each steer the recoveries were nearly equal to the recoveries when samples were taken 12 times daily from each steer.

These studies show that chromic oxide impregnated in paper can be administered daily or every other day with nearly complete recovery of the indicator within 3 days and that it is feasible to administer chromic oxide daily or on alternate days and to collect fecal grab samples on the same day in studies with steers fed hay in drylot.
