Developing a genome-wide selection model for genetic improvement of residual feed intake and carcass merit in a beef cattle breeding program
Download2012
Lai, S., Plastow, G., Zeng, Z., Li, X., Ma, J., Tang, G., Moore, S., Wang, Z.
Residual feed intake (RFI) and carcass merit (CM) are both complex traits emerging as critical targets for beef genetic improvement. RFI and CM traits are difficult and expensive to measure and genetic improvement for these traits through traditional selection methods is not very effective....

Impact of Feed Efficiency and Diet on Adaptive Variations in the Bacterial Community in the Rumen Fluid of Cattle
Download2012
Hernandez-Sanabria, E., Goonewardene, L. A., Durunna, O.N., Wang, Z., Moore, S S., Guan, L. L.
Limited knowledge of the structure and activities of the ruminal bacterial community prevents the understanding of the effect of population dynamics on functional bacterial groups and on host productivity. This study aimed to identify particular bacteria associated with host feed efficiency in...

Genome-wide analysis of zygotic linkage disequilibrium and its components in crossbred cattle
Download2012
Jiang, Q., Wang, Z., Yang, R. C., Moore, S. S.
Background Linkage disequilibrium (LD) between genes at linked or independent loci can occur at gametic and zygotic levels known asgametic LD and zygotic LD, respectively. Gametic LD is well known for its roles in fine-scale mapping of quantitative trait loci, genomic selection and evolutionary...

Influence of sire breed on the interplay among rumen microbial populations inhabiting the rumen liquid of the progeny in beef cattle
Download2013
Guan, L. L., Wang, Z., Zhou, M., Goonewardene, L. A., Moore, S. S., Hernandez-Sanabria, E.
This study aimed to evaluate whether the host genetic background impact the ruminal microbial communities of the progeny of sires from three different breeds under different diets. Eighty five bacterial and twenty eight methanogen phylotypes from 49 individuals of diverging sire breed (Angus,...

Voort, G. V., Sargolzaei, M., Wang, Z., Moore, S., Mandell, I., Lu, D., Kelly, M., Plastow, G., Miller, S.
Background Genetic improvement of beef quality will benefit both producers and consumers, and can be achieved by selecting animals that carry desired quantitative trait nucleotides (QTN), which result from intensive searches using genetic markers. This paper presents a genome-wide association...

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...

Candidate genes and biological pathways associated with carcass quality traits in beef cattle
Download2013
Karisa, B. K., Bruce, H. L., Plastow, G. S., Moore, S. S., Thomson, J., Wang, Z.
The objective of this study was to use the candidate gene approach to identify the genes associated with carcass quality traits in beef cattle steers at the University of Alberta Ranch at Kinsella, Canada. This approach involved identifying positional candidate genes and prioritizing them...

Inbreeding and Genetic Diversity in Three Imported Swine Breeds in China Using Pedigree Data
Download2013
Xue, J., Li, X. W., Zeng, Z. Y., Zhu, L., Yang, R. F., Wang, Z., Bai, L., Liu, T. F., Jiang, Y. Z., Tang, G. Q., Jiang, A. A., Lian, M. J.
The accumulation of inbreeding and the loss of genetic diversity is a potential problem in the modern swine breeds in China. Therefore, the purpose of this study was to analyze the pedigrees of Chinese Duroc (CD), Landrace (CL) and Yorkshire (CY) swine to estimate the past and current rates of...

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...

Genetic and Phenotypic Correlations between Performance Traits with Meat Quality and Carcass Characteristics in Commercial Crossbred Pigs
Download2014
Wang, Z., Kemp, R., van Haandel, B., Charagu, P., Zhang, C., Bruce, H., Miar, Y., McKay, R., Huisman, A., Plastow, G., Manafiazar, G., Moore, S.
Genetic correlations between performance traits with meat quality and carcass traits were estimated on 6,408 commercial crossbred pigs with performance traits recorded in production systems with 2,100 of them having meat quality and carcass measurements. Significant fixed effects (company, sex...
