On days 114 to 118 ruminal and fecal samples were collected from 180 steers and analyzed for pH, VFA, and total and acid-resistant Escherichia coli (E. coli) and coliforms. Ruminal (P=0.13) and fecal (P=0.10) VFA tended to decrease linearly as CGF increased. Consequently, there was a corresponding numerical linear increase in ruminal pH and a significant linear increase in fecal pH (P<0.05). Total and acid-resistant E. coli and coliforms, however, were not affected (P>0.10) by dietary treatment.BeefE. coliFood safetyFinishing cattleConference paper
