A Whole-Genome Scan to Map Quantitative Trait Loci for Conformation and Functional Traits in Canadian Holstein Bulls
Download2008
Grant, J. R., Moore, S. S., Xiu, Z., Murdoch, B. M., Kolbehdari, D., Stothard, P., Wang, Z., Prasad, A., Marques, E.
Genetic improvement of livestock populations can be achieved through detection and mapping of genetic markers linked to quantitative trait loci (QTL). With the completion of the bovine genome sequence assembly, single nucleotide polymorphism (SNP) assays spanning the whole bovine genome and...

Plastow, G., Durunna, O. N., Stothard, P., Mujibi, F. D. N., Moore, S. S., Wang, Z., Basarab, J. A., Nkrumah, D. J., Crews Jr, D. H., Mah, J.
The benefit of using genomic breeding values (GEBV) in predicting ADG, DMI, and residual feed intake for an admixed population was investigated. Phenotypic data consisting of individual daily feed intake measurements for 721 beef cattle steers tested over 5 yr was available for analysis. The...

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...

Construction of bovine whole-genome radiation hybrid and linkage maps using high-throughput genotyping
Download2007
Williams, J. L., Moore, S. S., Wang, Z., McKay, S. D., Murdoch, B. M.
High-density whole-genome maps are essential for ordering genes or markers and aid in the assembly of genome sequence. To increase the density of markers on the bovine radiation hybrid map, and hence contribute to the assembly of the bovine genome sequence, an Illumina® BeadStation was used to...

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....

Estimation of genetic and phenotypic parameters for ultrasound and carcass merit traits in crossbred beef cattle
Download2014
Bruce, H. L., Plastow, G. S., Moore, S. S., Wang, Z., Nkrumah, D., Miar, Y., Durunna, O.
Ultrasound measurements of 852 crossbred steers along with carcass merit measurements on 756 of them were used to examine their genetic and phenotypic parameters. Traits including ultrasound backfat thickness (UBF), ultrasound ribeye area (UREA), ultrasound marbling (UMAR), carcass weight (CWT),...

Goonewardene, L. A., Wang, Z., Yang, R. C., Huedepohl, C.
Data from the Alberta Agriculture Food and Rural Development data base, which keeps inventories of elk producers and velvet production information (n = 12 724), were used to estimate genetic and phenotypic variances, heritability and repeatability estimates for velvet antler using REML methods....

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...

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...

International genetic evaluations for feed intake in dairy cattle through the collation of data from multiple sources
Download2014
Coffey, M. P., Løvendahl, P., Wang, Z., de Haas, Y., Krattenmacher, N., Berry, D. P., Crowley, J. J., Pryce, J. E., Veerkamp, R. F., Weigel, K., Macdonald, K., Spurlock, D.
Feed represents a large proportion of the variable costs in dairy production systems. The omission of feed intake measures explicitly from national dairy cow breeding objectives is predominantly due to a lack of information from which to make selection decisions. However, individual cow feed...
