Two replications of 4 treatments, including (1) wet distillers grains fed in a bunk, (2) wet distillers grains fed on the ground on standing vegetation, (3) a 1:1 mixture of milo: soybean meal fed in a bunk, and (4) a control treatment of no supplement, were compared during a late-summer stocker steer grazing trial. Supplements were fed 3 times per week to supply CP at 0.14 kg/d per steer during the last half (77 d) of the growing season, mid-July to early October. Steers were weighed in May, mid-July, and October on pasture, and at the end of a feedlot finishing phase.</div></div><div><h3>Results and Discussion</h3><div>During the last half of the grazing season in 2011 to 2014, animal daily gains were greater for supplemented groups compared with the nonsupplemented control group (0.77 to 0.81 kg/head per day vs. 0.70 kg/head per day, supplemented vs. nonsupplemented, respectively). Gains on pasture from supplemented groups, including the wet distillers group fed on the ground, were not different from each other.

Literature was excluded from this review if the study solely evaluated cow-calf or feedlot enterprises.
