Goonewardene, L. A., Erichsen, C. M., Price, M. A., Liu, M. F., Berg, R. T.
Phenotypically dehorned (genetically horned) and polled bulls were similar for birth, weaning weight, pre- and post-weaning ADG, carcass weight, grade fat, marbling, rib-eye area, cutability and carcass grade. Polled bulls had higher (P < 0.02) fat over the rib-eye compared with dehorned. The...

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...

Association analyses of a SNP in the promoter of OLR1 with growth, feed efficiency, fat deposition, and carcass merit traits in hybrid, Angus and Charolais beef cattle

Chen, L., Islam K., Li, C., Vinsky, M.
A single nucleotide polymorphism (SNP) in the promoter region of oxidized low density lipoprotein (lectin-like) receptor 1 (OLR1) (c. −495 T>C) was identified and analyzed for associations with 10 traits related to growth, feed efficiency, body fat deposition and carcass merit traits in hybrid...

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...

CANDIDATE GENES, METABOLITES AND BIOLOGICAL PATHWAYS ASSOCIATED WITH RESIDUAL FEED INTAKE AND CARCASS QUALITY IN BEEF CATTLE
DownloadFall 2013
The main objective of this study was to identify genes, DNA variants and plasma metabolites associated with residual feed intake (RFI) in beef cattle. In the first study, a total of 117 SNPs were selected and genotyped in 531 steers at the University of Alberta. The population was split into a...

Characterization and evaluation of residual feed intake measured in mid- to late-gestation mature beef cows and relationships with circulating serum metabolites and linear body measurements

Miller, S. P., Swanson, K. C., Wood, K. M., Montanholi, Y. R., Fitzsimmons, C. F, McBride, B. W.
To evaluate the use of residual feed intake (RFI) models measured in mid-to-late gestating beef cows, a dataset was used combining data from five experiments containing nine treatment and/or replicate groups for a total of 321 animal records. Investigations of RFI models included the effects of...

Contribution of the Rumen Epithelial Transcriptome and Microbial Community to Variation in Beef Cattle Feed Efficiency
DownloadSpring 2016
Feed efficient cattle consume less feed and produce less environmental waste than inefficient cattle. Many factors are known to contribute to differences in feed efficiency. However, it is unknown how the rumen epithelium and its associated microorganisms influence the feed efficiency of cattle....

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....

Effects of Selection for Low Residual Feed Intake on Meat Quality of Major Muscles from Angus, Charolais and Kinsella Composite Cattle
DownloadFall 2017
Residual feed intake (RFI) is a measure of animal feeding efficiency. Selection of high feed efficient cattle using RFI does not affect production performance; low RFI animals consume less feed to reach a similar body weight gain as high RFI animals and thus are considered as feed efficient...

The effects of zeranol were studied in 24 steers and 24 bulls starting at an average weight of 200 kg for a trial period of 183 days. Bulls grew faster than steers (P = 0.07) and zeranol-treated cattle showed higher average daily gain than controls (P < 0.05); there was no significant interaction...
