Midseason and weaning weights of calves in the fenbendazole-treated group averaged 22.4 and 33.5 lb heavier (P<.04), respectively, than controls. Cow and calf fecal egg counts were low throughout the grazing season and were not materially affected by treatment.BeefFenbendazolePerformanceFecal eggsConference paper
