yearling steers, protein supplementation, energy supplementation, native range, crested wheatgrass
Seventy-two yearling, black baldy steers were utilized in a grazing experiment to study the effect of late summer, early fall protein (2.33 Ib., 40% all natural, fed each Monday, Wednesday and Friday) or energy (4.4 Ib. corn fed daily) supplementation on average daily gain. Two pasture types, mixed native range and crested wheatgrass, were also examined. Cattle were purchased in May as part of a larger group and gained an average of 2.16 Ib. per head daily prior to initiation of the study on September 9, 1988. Average daily gain was significantly greater (P = .012) for cattle grazing crested wheatgrass than for steers grazing native range (1.38 vs .62 Ib. per head daily, respectively). Differences in daily gain due to supplement fed were not statistically significant (P = .298). Daily gains for the control, corn and protein group across both pasture types were .77, 1.02 and 1.22 Ib. per head daily, respectively.
