Rumensin was fed at 10 g/ton of feed for 28 days and 20 g/ton thereafter. The starter and standard creep rations were self-fed to both the drylot and pasture groups. Drylot calves outgained calves on pearl millet pasture 196 lbs to 140 lbs during the 76-day pasture trial. Rumensin decreased fecal samples containing coccidial oocytes and improved total gain 5.5% and feed efficiency 4.8%.BeefDrylot vs. Pasture SystemsEarly-weaned calvesConference paper
