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...

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...

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....

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...

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...

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...

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...

The objective was to determine if end-of-test residual metabolizable energy intake (RMEI) is correlated with RMEI values calculated earlier in the test on steers fed two forage (silage) or four forage-grain diets. As the days on test increased the variation in RMEI decreased in all diets. In all...

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,...
