Residual feed intake adjusted for backfat thickness and feeding frequency is independent of fertility in beef heifers
Download2011
McCartney, D., Ambrose, D. J., Colazo, M. G., Baron, V. S., Novak, S., Basarab, J. A.
This study examined the effects of residual feed intake (RFI), RFI adjusted for off-test backfat thickness (RFIfat) and RFI adjusted for off-test backfat thickness and feeding event frequency (RFIfat & activity) on heifer fertility and productivity. Beef heifers (n=190) were monitored for...

Modification of muscle inherent properties through age at slaughter, growth promotants and breed crosses

Bruce., H. L., Aalhus, J. L., Larsen, I. L., Girard, I., Basarab, J. A.
A 24 factorial experiment tested the interactions of slaughter age (12–13 or 18–20 mo), growth hormone use, β-adrenergic agonist (β-AA) use and breed cross [Hereford–Aberdeen Angus (HAA) or Charolais–Red Angus (CRA)] on the composition, fibre types, and connective tissue characteristics of m....

Aalhus, J. L., Basarab, J. A., Girard, I., Bruce., H. L., Larsen, I. L.
A 23 factorial experiment tested the interactions of slaughter age (12–13 or 18–20 mo), growth implants use (Component E-S, TE-S), ractopamine hydrochloride (RAC) feed supplementation use and breed cross [Hereford–Aberdeen Angus (HAA) or Charolais–Red Angus (CRA)] on pH, temperature, objective...

Proteome differences associated with fat accumulation in bovine subcutaneous adipose tissues
Download2010
Basu, U., Guan, L., Dodson, M. V., Zhao, Y. M., Basarab, J. A.
Background The fat components of red meat products have been of interest to researchers due to the health aspects of excess fat consumption by humans. We hypothesized that differences in protein expression have an impact on adipose tissue formation during beef cattle development and growth....

Crossbreeding is an effective method for improving the efficiency of production in commercial cow-calf operations. It exploits available heterosis (hybrid vigour) and complementarity between different breeds or populations (lines). Before adopting a crossbreeding system, commercial cattle...

Subcutaneous fatty acid composition of steers finished as weanlings or yearlings with and without growth promotants
Download2013
Baron, V. S., Aalhus, J. L., Turner, T. D., Dugan, M. E. R., Mapiye, C., Basarab, J. A.
Background The current study evaluated the subcutaneous fatty acid (FA) composition of calf- and yearling-fed steers with or without growth promoting implants. Crossbred steers (n = 112; 267 ± 5.0 kg) of the same contemporary group were allocated to one of four production system and implant...

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)...

Swath grazing triticale and corn compared to barley and a traditional winter feeding method in central Alberta, Can
Download2014
Doce, R. R., Dick, C., Baron, V. S., Basarab, J. A.
A 5-yr study compared swath-grazed triticale (× Triticosecale Wittmack), corn (Zea mays L.) and barley (Hordeum vulgare L.) with a traditional pen-fed, wintering diet for gestating beef cows on the basis of dry matter (DM) yield, carrying capacity, nutritive value, cow performance and total daily...

Steaks from longissimus lumborum and semimembranosus muscles, aged 2 or 27 d, were obtained from a population of steers (n=112) managed to produce a range in tenderness (shear force range from 2.57 to 17.2 kg). All available carcass (live weight, hot commercial weight, pH, temperature, marbling,...

Characterization of microRNA expression in bovine adipose tissues: A potential regulatory mechanism of subcutaneous adipose tissue development
Download2010
Jin, W., Guan, L., Dodson, M. V., Basarab, J. A., Moore, S. S.
Background MicroRNAs (miRNAs), a family of small non-coding RNA molecules, appear to regulate animal lipid metabolism and preadipocyte conversion to form lipid-assimilating adipocytes (i.e. adipogenesis). However, no miRNA to date has been reported to modulate adipogenesis and lipid deposition...
