a–cMeans within a row with different superscripts differ (P ≤ 0.05).
1PST = crested wheatgrass and native range; ANN = crested wheatgrass, native range, field pea–barley, and unharvested corn; FLT = feedlot control.
2SEM of the least squares mean (n = 3 replications/yr).
3ANN: one steer died of bloat after entry into unharvested corn; FLT: one steer bloated and died each year.
4Trt = treatment.
5Means with P ≤ 0.05 differ significantly.
