There has recently been great interest in applying theoretical quantitative genetic models to empirical studies of evolution in wild populations. However, while classical models assume environmental constancy, most natural populations exist in variable environments. Here, we applied a novel...

Genetic parameters for production and feeding behaviour traits in crossbred steers fed a finishing diet at different ages
Download2013
Wang, Z., Nkrumah, D. J., Basarab, J. A., Durunna, O. N., Okine, E. K., Moore, S. S., Mujibi, F. D. N.
Because cattle can be raised postweaning under several feeding regimes, this study examined the consistency of phenotypic and genetic parameters of some production and feeding behaviour traits between two feeding periods that beef cattle received a finisher diet. Crossbred steers (n=851) were...

Goldfish ghrelin: Molecular characterization of the complementary deoxyribonucleic acid, partial gene structure and evidence for its stimulatory role in food intake
Download2002
Rivier, J., Kaiya, H., Lin, X.W., Cervini, L., Unniappan, S., Peter, R.E., Kangawa, K.
Complementary deoxyribonucleic acid (cDNA) encoding goldfish preproghrelin was identified using rapid amplification of the cDNA ends (RACE) and reverse transcription (RT)-polymerase chain reaction (PCR). The 490 bp cDNA encodes a 103 amino acid preproghrelin which has a 26 amino acid signal...

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...

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...
