A comparison of reproductive and growth traits of horned and polled cattle in three synthetic beef lines

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...

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...

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...

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...

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...

The growth and distribution of fat from 163 pig carcasses were compared among five breeds (Duroc × Yorkshire (D × Y), Hampshire × Yorkshire (H × Y), Yorkshire (Y × Y), Yorkshire × Lacombe-Yorkshire (Y × L-Y) and Lacombe × Yorkshire (L × Y)) and two sex-types (barrows and gilts) over a wide range...

The relative growth and distribution of bone from 256 bovine carcasses were compared among three breed-types (British, up to 30% Charolais and 30-50% Charolais) and three \"sexes\" (heifers, steers and bulls) over a wide range in carcass weight.
