Phenotypically dehorned (genetically horned) and polled bulls were similar for birth, weaning weight, pre- and post-weaning ADG, carcass weight, grade fat, marbling, rib-eye area, cutability and carcass grade. Polled bulls had higher (P < 0.02) fat over the rib-eye compared with dehorned. The...

Tennessen, T., Berg, R. T., Price, M. A.
Seven groups of six bulls and seven groups of six steers were transported separately by truck for either 10 min or 2 h. Body weight, rectal temperature, respiratory rate, serum cortisol, and a chute score were recorded before and after trucking. Heart rate was monitored by telemetry in one animal...

The effects of zeranol were studied in 24 steers and 24 bulls starting at an average weight of 200 kg for a trial period of 183 days. Bulls grew faster than steers (P = 0.07) and zeranol-treated cattle showed higher average daily gain than controls (P < 0.05); there was no significant interaction...

Thirty-two cull cows aged from 1 to 13 yr were allocated to five age groups and fed individually for 82 days, then slaughtered. Half of the cows within each group were implanted with 36 mg of zeranol. Zeranol had no significant effect on average daily gain, feed efficiency or backfat thickness,...

The effects of breed-type, sex and age on the density of four bovine limb bones were studied. The density of the four limb bones increased significantly with age, but the effects of breed-type and sex were variable. The results are discussed with reference to the densiometric method of predicting...

The influence of dietary roughage level on the efficiency of growth and muscle deposition in bulls and steers

Hardin, R. T., Jones, S. D. M., Berg, R. T., Price, M. A.
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 influence of Zeranol on feedlot performance and carcass traits of culled cows and heifers
Download1982
A total of 126 cows and heifers culled from the University of Alberta beef herd were used in an experiment to study the effects of zeranol, an anabolic growth stimulant. The cattle were divided into two groups: 67 aged less than 4 yr (young) and 59 aged more than 4 yr (mature); within each group,...

The influences of feed energy level on growth and carcass traits in bulls of two breed types
Download1984
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...
