Effects of production system and growth promotants on the physiological maturity scores in steers
Download2014
Aalhus, J. L., Basarab, J. A., N. Prieto, I. L., López-Campos, Ó., Larsen, M.
Over a 2-yr period, 224 crossbred steers were allotted to a 2×2×2 factorial arrangement of treatments to determine the effect of the production system (calf-fed vs. yearling-fed), growth implant strategy (non-implanted vs. implanted) and β-agonist supplementation (no ractopamine vs. ractopamine)...

Greenhouse gas emissions from calf- and yearling-fed beef production systems, with and without the use of growth promotants

Baron, V. S, Aalhus, J. L., Basarab, J. A., López-Campos, Ó., Haugen-Kozyra, K., Okine, E. K.
A spring calving herd consisting of about 350 beef cows, 14–16 breeding bulls, 60 replacement heifers and 112 steers were used to compare the whole-farm GHG emissions among calf-fed vs. yearling-fed production systems with and without growth implants. Carbon footprint ranged from 11.63 to 13.22...

Four Alpine does were used in a 4 × 4 Latin square design to determine the effects of feeding canola oil at four levels: 0, 2, 4 and 6% on milk fatty acid profile. The sum of C12:0 + C14:0 + C16:0(hypercholesterolemic fatty acids) decreased linearly and C18:0 + C18:1: C16:0 (indicator of...

Two-hundred and twenty-four spring-born British×Continental crossbred steers were used in a 2-yr project to evaluate the effect of production system (calf-fed vs. yearling-fed) and its interaction with breed cross and hormone implant strategies, with and without β-adrenergic agonist on carcass...

The objective was to determine if end-of-test residual metabolizable energy intake (RMEI) is correlated with RMEI values calculated earlier in the test on steers fed two forage (silage) or four forage-grain diets. As the days on test increased the variation in RMEI decreased in all diets. In all...

Study of Carcass, organ, muscle, fat tissue weight and concentration in rats fed CLA or its precursors by Principal Component Analysis
Download2004
Mir, Z., Wang, Z., Goonewardene, L. A., Okine, E. K., Mir, P. S.
Carcass, organ and muscle weight, and fat tissue data were obtained from 30 weaned male Wistar rats fed one of three diets, (10 rats/diet) over a period of 60 d. The diets were base with synthetic conjugated linoleic acid (CLA), sunflower oil or beef enriched CLA. The CLA diet contained the base...

Tissue distribution in primal cuts of Canadian beef composites and opportunities for harvesting younger and leaner cattle

Goonewardene, Laksiri A., Basarab, John A., Wang, Z., Price, Megan A., Ramsey, P., Marx, T., Aalhus, J., Seneviratne, R. W., Yalingasinghe, W. G. N. P., Okine, Erasmus K.
The objectives were to compare weights and proportions (%) of muscle (M), fat (F) and bone (B) in the carcass, primal cuts (brisket, loin and short loin, chuck, flank, plate, rib, round and shank) and fat depots in three BeefBooster® composites (n = 176) from 274-456 days at slaughter, and...
