Price, M. A., Berg, R. T., Jones, S. D. M., Mathison, G. W.
A serial slaughter experiment is described comparing 45 bulls and 44 implanted steers. Nine of each 'sex' were slaughtered at the start of the trial and the remaining 71 were fed diets containing three roughage levels (20%, 50% and 80% alfalfa-brome hay) to two pen-average slaughter weights (450...

An experiment is described comparing bulls and implanted steers fed diets containing three roughage levels (20, 50 and 80% alfalfa–brome hay) with two pens of four cattle in each ’sex’ × dietary roughage level subgroup. Cattle were about 12 mo old and 230kg at the start of the trial. Each animal...

Makarechian, M., Butson,S., Price, M. A.
A serial slaughter experiment is described using 48 yearling bulls: 24 Hereford crossbred (HX) and 24 Beef synthetic (SY). Twelve bulls of each breed type were fed a high-energy, mainly grain diet (Hi) and the other 12 a pelleted alfalfa diet (Lo). The two breed types showed similar growth rate...

The relative growth and distribution of bone from 256 bovine carcasses were compared among three breed-types (British, up to 30% Charolais and 30-50% Charolais) and three \"sexes\" (heifers, steers and bulls) over a wide range in carcass weight.

The cooking and eating quality characteristics of rib-eye roasts obtained from cows after removal from the breeding herd and after 8 or 16 wk of realimentation were determined. Evaluations of the effects of maturity class (physiological age) and external fatness on meat quality were also made....

Berg, R. T., Price, M. A., Jones, S. D. M.
Two breeds (Hereford (HE), and Dairy Synthetic (DY)), and two sexes (bulls and heifers) were compared for various measures of efficiency in beef production. DY animals had greater (P < 0.001) birthweights, and greater weaning weights (P < 0.001) than HE animals. At weaning, 16 animals of each...
