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 influence of dietary roughage level on the efficiency of growth and muscle deposition in bulls and steersDownload
Bulls and implanted steers fed three dietary roughage levels (20% 50%, and 80% alfalfa-brome hay) were compared for various measures of efficiency in beef production. Cattle were about 1 yr of age at the start of the trial and bulls were heavier than steers (290 kg vs. 269 kg). There were four...
The effects of increasing dietary roughage level and slaughter weight on the feedlot performance and carcass characteristics of bulls and steersDownload
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...
The effects of dietary roughage level on the feedlot performance and carcass characteristics of bulls and steersDownload
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...
