Modification of beef quality through steer age at slaughter, breed cross and growth promotants
Download2012
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...

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....

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...

Prediction of residual feed intake for first lactation dairy cows using orthogonal polynomial random regression
Download2013
Okine, E. K., Goonewardene, L. A., McFadden, T., Basarab, J. A., Wang, Z., Manafiazar, G., Li, P.
Residual Feed Intake (RFI) is a measure of energy efficiency. Developing an appropriate model to predict expected energy intake while accounting for multifunctional energy requirements of metabolic body weight (MBW), empty body weight (EBW), milk production energy requirements (MPER), and their...

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....

Quantitative trait loci affecting Rous Sarcoma Virus induced tumor regression trait in F2 intercross chickens
Download2009
Uemoto, Y., Mitsuhashi, T., Saburi, J., Miyata, T., Suzuki, K., Odawara, S., Yamashita, H., Yamamoto, R., Sato, S-I., Plastow, G., Kobayashi, E., Irina, C., Ohtake, T.
We performed a genome-wide linkage and quantitative trait locus (QTL) analysis to confirm the existence of QTL affecting Rous Sarcoma Virus (RSV) induced tumor regression, and to estimate their effects on phenotypic variance in an F2 resource population. The F2 population comprised 158 chickens...

Baron, V. S., López-Campos, Ó., Aalhus, J. L., Basarab, J. A., Juárez, M.
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...

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...

Plastow, G., Stothard, P., Moore, S., Bao, H., Meng, Y., Liao, X.
Gene duplication is a widespread phenomenon in genome evolution, and it has been proposed to serve as an engine of evolutionary innovation. In the present study, we performed the first comprehensive analysis of duplicate genes in the bovine genome. A total of 3131 putative duplicated gene pairs...

Short communication: Erythrocytes assayed early ante-mortem can predict adipose tissue and muscle trans-18:1 isomeric profiles of steers fed red clover silage supplemented with flaxseed
Download2013
Aalhus, J. L., Rolland, D. C., M. E. R. Dugan, Baron, V. S., Mapiye, C., Basarab, J. A., Turner, T. D., Block, H. C., McAllister, T. A., Uttaro, B.
Steers were fed a red clover silage-based diet with or without flaxseed to evaluate over time the effects of flaxseed supplementation on erythrocytes (ERC) trans(t)18:1 isomers composition and their relationships to adipose tissue and muscle t18:1 profiles at slaughter. Concentrations of most ERC...
