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...

A technique is described for meausuring increases in bone length during defined periods before slaughter in cattle. It consists of jugular infusions of oxytetracycline at specified time intervals. Oxytetracycline identifies the sites of ossification in growing bones at the time of infusion by...

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...

In a calving ease comparison involving 106 calves born to first calf heifers, calves sired by Red Angus bulls were heavier at birth and required more calving assistance than Corriente-sired calves. However, the easier calving Corriente-sired calves experienced equivalent death loss and were...

Three groups of once-calved (OCH) heifers were slaughtered following the weaning of their calves at 3 (OCH3, n = 32), 5 (OCH5, n = 33) and 7 (OCH7, n = 31) months postcalving. A fourth group of heifers was fed a silage/grain diet and slaughtered at 15 mo of age (C, n = 32). Alternate sides of...

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...

Ten yearling wapiti stags were used to investigate effects of winter nutrition on subsequent growth on summer pasture. One group of five (LOW) was wintered on medium-quality hay, and the other group of five (HIGH) was wintered on hay and alfalfa–barley pellets (16% crude protein). By the time...

Asamoah, S. A., Bork, E. W., Irving, B. D., Hudson, R. J., Price, M. A.
Native Aspen Parkland landscapes consist of a complex mosaic of plant communities, including riparian meadows, upland grasslands, and forests. Sustainable livestock production in this environment depends on an understanding of livestock grazing behavior among communities, particularly under...

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...
