We evaluated the temporal dynamics of herbage biomass and protein within riparian meadows and upland grasslands of native Aspen Parkland rangeland to understand the contribution of each to lives tock foraging. For the growing season monitored, meadows were greater in forage yield and crude...

Four diets in which peas progressively replaced barley [0% (0P), 30% (30P), 50% (50P), and 100% peas (100P)] and one in which canola meal (CM) replaced 10% of the barley, were fed to 90 beef heifers (initial weight 215.8 ± 13.8 kg). The heifers achieved average daily gains (ADGs) of 0.72, 0.80,...

Cattle herbage utilization patterns under high density rotational grazing in the Aspen Parkland
Download2003
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...

Fibre-type characteristics and postmortem glycolysis of bison (Bison bison bison) longissimus lumborum
Download2002
Aalhus, J. L., Janz, J. A. M., Price, M. A.
To augment the limited information base, muscle fibre and postmortem glycolytic data from bison longissimus lumborum were compiled. As expected, postmortem glycogen concentration and pH declined while lactate concentration increased. Bison muscle fibres had a greater area, with a greater...

Meat quality of bison (Bison bison bison) Longissimus thoracis et lumborum following very fast chilling
Download2002
Aalhus, J. L., Janz, J. A. M., Price, M. A.
Very fast chilling (VFC; internal muscle temperature of -1°C by 5 h postmortem) was achieved in the longissimus lumborum (LL), but not in the semimembranosus, of lean bison carcasses after only 4 or 6 h of chilling at -35°C. Rigorous chilling caused a shift in moisture loss from carcass cooler...

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...

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...

Comparison of Objective External Carcass Measurements and Subjective Conformation Scores for Prediction of Lamb Carcass Quality
Download1997
McClelland, L. A., Woloschuk, C. M., S. D. M. Jones., Stanford, K., Price, M. A.
Carcass measurements were collected from 1505 lambs over a 2-yr period by a single technician. The lambs (rams, ewes and wethers) were classified as either meat-type or wool-type, with meat-type subdivided by frame size into light, medium or large. Carcass measurements included carcass length...

Jones, S. D. M., Price, M. A., Coupland, T., Robertson, W. M.
A total of 281 lamb carcasses covering three weight groups (18–22.9, 23–25.9 and 26–30 kg) and fatness (< 3 mm, 3–5 mm and > 5 mm) were used to determine the usefulness of several carcass measurements for predicting saleable meat yield. Carcasses were measured for fat and muscle depth, 3–4 cm...

One hundred and thirty-four pregnant beef cows (liveweight = 544.3 kg ± 73 3 kg SD; condition score = 3.5 ± 0.3 SD), were randomly assigned in January to five management treatments (combinations of feed restriction and weaning time) to study the effects on calving and rebreeding performance....
