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...

Goonewardene, L. A., Erichsen, C. M., Price, M. A., Liu, M. F., Berg, R. T.
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...

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...

Effect of postweaning implantation of zeranol and dietary energy level on growth and reproductive performance of replacement beef heifers
Download1991
Makarechian, M., Arthur, P. F., Price, M. A.
Eighty-one heifer calves weaned at an average age of 6 mo were used to study the effect of postweaning zeranol implantation, on the growth and reproductive performance of heifers fed to grow slowly on three dietary energy levels. Forty heifers were implanted with 36 mg of zeranol at 30 d and...

Jeremiah, L. E., Newman, J. A., Price, M. A., Jones, S. D. M., Vincent, B. C.
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...

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...

A fully functional grading or classification system must allow trading in carcasses and meat to be conducted without the buyer needing to inspect the product personally. To achieve this, the system must accurately indicate the quantity of meat, the intrinsic quality of the meat, and any aspects...

Price, M. A., Berg, R. T., Jones, S. D. M.
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...
