Effects of an energy or protein supplement on forage dry matter intake for steers grazing summer native range

Information on a study which determines the effects of supplementation level and type on forage intake of steers grazing a high-quality native range is presented. This study was conducted in late May through the end of June. On d 0, steers were randomly assigned to one of 5 dietary treatments, fed once daily in individual stalls for 28 d. Treatments were control (no supplement, n=4), or supplemented with either cottonseed meal or dry rolled corn, each at either 0.45 kg or 1.81 kg as-fed/d (n=3 for each combination).
