In Exp. 1, six individually fed Hereford steers were exposed to hot (HOT) or thermoneutral (TNL) environmental conditions (ENV) while being adapted (stepped-up) to a finishing diet by decreasing roughage level from 55 to 10% of the diet DM over 17 d.

Twenty crossbred steers were assigned to one of two treatment groups: control (sham-injected; n = 10) and treated (n = 10) to determine the effect of prior treatment as calves with recombinant bovine somatotropin (rbST) on growth and carcass traits o

Light-test weight corn (59.2 to 61.5 kg/hL; 46 to 48 lb/bu) was compared to normal corn (72 kg/hL; 56 lb/bu) in growing and finishing diets for large-frame crossbred steer calves in 2 consecutive yr. The source of the calves was the same each year as
