Changes in body weight during the course
of the experiment. Purebred Hereford (HH) steers had
lower (P < .05) weaning weights (d 210) than Brahman ´
Hereford (BH) or Hereford ´ Brahman (HB) steers;
purebred Brahman (BB) weaning weights were intermediate.
At slaughter, BH steers had greater (P < .05)
final body weights than BB steers, and body weights for
HB and HH steers were intermediate. Pooled mean
square error bars (SEM) are affixed to the data points for
the BB steers. Biopsy times are indicated.
