A Simple Polymerase Chain Reaction-based Method for the Discrimination of Three Chicken Breeds
Download2009
Mitsuhashi, T., Kubo, Y., Plastow, G.
A large number of branded chicken products exist in Japan, and in some cases, the breed of chicken is an important factor used to attract consumer interest in the retail product. In order to establish a simple method for verifying such breed claims we applied the amplified fragment length...

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...

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...

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
Download2014
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...

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...

Genetic parameters for production and feeding behaviour traits in crossbred steers fed a finishing diet at different ages
Download2013
Wang, Z., Nkrumah, D. J., Basarab, J. A., Durunna, O. N., Okine, E. K., Moore, S. S., Mujibi, F. D. N.
Because cattle can be raised postweaning under several feeding regimes, this study examined the consistency of phenotypic and genetic parameters of some production and feeding behaviour traits between two feeding periods that beef cattle received a finisher diet. Crossbred steers (n=851) were...

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...

Prediction of residual feed intake for first lactation dairy cows using orthogonal polynomial random regression
Download2013
Okine, E. K., Goonewardene, L. A., McFadden, T., Basarab, J. A., Wang, Z., Manafiazar, G., Li, P.
Residual Feed Intake (RFI) is a measure of energy efficiency. Developing an appropriate model to predict expected energy intake while accounting for multifunctional energy requirements of metabolic body weight (MBW), empty body weight (EBW), milk production energy requirements (MPER), and their...

Single nucleotide polymorphisms for feed efficiency and performance in crossbred beef cattle
Download2014
Squires, J. J., Moore, S., Stothard, P., Swanson, K. C., Miller, S. P., Abo-Ismail, M. K., Vander Voort, G., Liao, X., Plastow, G., Mandell, I. B.
Background This study was conducted to: (1) identify new SNPs for residual feed intake (RFI) and performance traits within candidate genes identified in a genome wide association study (GWAS); (2) estimate the proportion of variation in RFI explained by the detected SNPs; (3) estimate the...
