Nalaila, S., Li, C., Moore, S. S., Stothard, P., Wang, Z.
Quantitative trait loci (QTL) mapped to large chromosomal regions have limited utility as DNA markers for marker-assisted selection (MAS) and are less informative as a reference for the identification of the underlying causative quantitative trait nucleotides (QTN). The objective of this study...

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
Download2013
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...

A whole genome scan was conducted to identify and fine map QTL regions for ultrasound and carcass merit traits in beef cattle. A total of 465 steers and bulls, genotyped for 4592 SNPs, were analysed for 16 ultrasound and carcass merit traits using interval mapping, single marker regression and...

Makarechian, M., Tennessen, T., Mathison, G. W., Price, M. A.
Fifty-three cross-bred bulls, aged 5–7 mo, were divided at random into a nonimplanted control group of 26 bulls and a treatment group of 27 bulls, which were each implanted with 36 mg of zeranol on the 1st, 81st, and 155th day of the experiment. They were fed a high energy diet ad libitum for 168...

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),...

Application of Multi-Omics Tools to Study the Genetic Background of Economically Relevant Traits in Commercial Beef Production
DownloadSpring 2022
The sustainability and profitability of beef cattle production are largely associated with feed efficiency, carcass merit, and resistance to infectious diseases. These traits are difficult or expensive to measure on individual animals, which makes them suitable for genomic application. Currently...

Feed efficiency affects profitability and sustainability in beef production systems. Since ruminal microbes play essential roles in feed digestion and conversion, the overall objective of this project was to investigate the association between ruminal bacteria and feed efficiency of beef cattle....

Bovine Spongiform Encephalopathy (BSE) belongs to a group of neurodegenerative diseases known as transmissible spongiform encephalopathies (TSEs) which affect many species. From 1986 more than 184,000 cattle in the UK have been confirmed to be infected with this disease, and in Canada total...

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....
