A comparison of reproductive and growth traits of horned and polled cattle in three synthetic beef lines
Download1999
Pang, H., Price, M. A., Goonewardene, L. A., Berg, R. T.
One hundred and thirty-seven cow-calf pairs on pasture in southeastern Alberta, were randomly allocated to one of two treatments no supplement (NOS) or a high by-pass protein (70% of CP) creep supplement (HPS) at an intake of 1.5 kg head−1 d−1. Calf weaning weights and pre-weaning ADG were higher...

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...

Data from carcasses of 210 cattle (119 bulls and 91 steers) from 4 breed types, serially slaughtered from = 200-008kg kg liveweight were used to test the hypothesis of similar gender dimorphism among breeds in relation to carcass bone growth and distribution. Relative to total bone weight, breed...

Variations in and relationships between reproductive performance and growth parameters in yearling beef bulls in single sire mating at pasture

Makarechian, M., Farid, A., Berg, R. T., Price, M. A.
Yearling bull fertility, measured as pregnancy rate, percentage of calves born during the first 4 and 6 wk of calving and mean and median of calving date distribution, were studied in 109 single-sire breeding herds of two breed groups over a 10-yr period. The breed groups were Herefords bulls...

Data on 99 young bulls, which were the progeny of matings of either double muscle bulls and normal cows (DMx) or normal bulls and normal cows (N) born over three calving seasons, were analyzed to compare the carcass characteristics and lean yield of yearling DMx and N bulls. DMx carcasses had...

Thirty-five non-pregnant beef cows in three age classes (< 4 yr, 4–5 yr, and > 5 yr) were allocated at random to two treatments (fed, unfed) soon after weaning in November 1978. On day 1, the unfed group of 17 cows were marketed and the fed group of 18 cows were introduced to grain feeding. After...

A trial is reported comparing the accumulation of lipid in rib cuts from 12 bull and 12 heifer carcasses from two breed types: Hereford (HE) and Dairy Synthetic (DY). Serial slaughter was carried out from weaning (163 ± 15.1 (SD) days) to approximately 16 mo of age. The left side of each carcass...

The influence of dietary roughage level on the efficiency of growth and muscle deposition in bulls and steers
Download1981
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 breed on the efficiency of growth and muscle deposition in bulls and heifers
Download1981
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...

A trial is reported comparing half-carcass fat partitioning in 12 bulls and 12 heifers each of two breed-types: Hereford (HE) and Dairy Synthetic (DY). These animals were serially slaughtered from weaning (163 ± 15.1 (SE) days) to approximately 16 mo of age. After slaughter, one side of each...
