Least square means within a row lacking a common superscript differ (p ≥ 0.05).
SEM, standard error of the LS mean.
CON, 40% crude protein cottonseed meal-based supplement on dormant native range; CORN, corn and soybean meal-based supplement on dormant native range; LGWP, reduced rate of gain on wheat pasture; HGWP, high rate of gain on wheat pasture.
