Clawson,M. L., Wang, Z., Stothard, P., McKay, S., Laegreid, W. W., Williams J. L., Murdoch, B. M., Settles, M., Moore, S. S., Prasad, A.
Background Classical bovine spongiform encephalopathy (BSE) is an acquired prion disease that is invariably fatal in cattle and has been implicated as a significant human health risk. Polymorphisms that alter the prion protein of sheep or humans have been associated with variations in...

A high resolution radiation hybrid map of bovine chromosome 14 identifies scaffold rearrangement in the latest bovine assembly
Download2007
Stothard, P., Wang, Z., de Givry, S., Marques, E., Moore, S. S., Womack, J., Murdoch, B.
Background Radiation hybrid (RH) maps are considered to be a tool of choice for fine mapping closely linked loci, considering that the resolution of linkage maps is determined by the number of informative meiosis and recombination events which may require very large mapping populations....

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...

An Assessment of Population Structure in Eight Breeds of Cattle Using a Whole Genome SNP Panel
Download2008
Schnabel, R. D., Wang, Z., Taylor, J. F., Gill, C. A., Van Tassell, C. P., Gao, C., Aerts, J., Williams, J. L., Neto, E. D., Murdoch, B. M., Matukumalli, L. K., Coppieters, W., McKay, S. D., Mannenl, H., Crews, D., Moore, S. S.
Background Analyses of population structure and breed diversity have provided insight into the origin and evolution of cattle. Previously, these studies have used a low density of microsatellite markers, however, with the large number of single nucleotide polymorphism markers that are now...

Association of a single nucleotide polymorphism in the bovine leptin gene with feed intake, feed efficiency, growth, feeding behaviour, carcass quality and body composition
Download2004
Hansen, C., Murdoch, B., Guercio, S., Basarab, J. B., Moore, S. S., Meng, Y., Li, C., Nkrumah, J. D.
Leptin is a 16-kDa-hormone product of the obese gene synthesized and expressed predominantly by adipose tissues, which has been shown to play major roles in the regulation of body weight, feed intake, energy balance, fertility, and immune system functions. We report an investigation into 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...

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...

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...

Meghen, C. N., Platz, S. S., Hu, X. S., Moore, S. S., Simila, J., Plastow, G.
Estimating animal abundance in industrial scale batches of ground meat is important for mapping meat products through the manufacturing process and for effectively tracing the finished product during a food safety recall. The processing of ground beef involves a potentially large number of...
