摘要: Abstract Relationships of temperament evaluated at different production stages with growth, carcass characteristics and beef tenderness were determined in Bonsmara crossbred steers managed under commercial managent. Temperament was weaning initiation the finishing phase. Steers from a Roswell, NM ranch (n = 156) Cline, TX (n = 21) stratified fall by weight source randomly allotted to winter ryegrass Uvalde or Overton, followed feeding feedlot near Batesville, TX. Cattle observed for (escape velocity, EV, m/s; pen chute score, PTS CTS) upon entry feedlot. harvested approximately 7 mm 12th rib fat. Carcass data taken 36 hrs post-mortem 2.5 cm thick steaks removed 13th Warner–Bratzler shear force (WBS) determination. The only measures significantly related performance EV PTS. Weaning appeared be more ADG (r = −0.26, P
