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...

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...

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...

Linkage disequilibrium (LD) and the persistence of its phase across populations are important for genomic selection as well as fine scale mapping of quantitative trait loci (QTL). However, knowledge of LD in beef cattle, as well as the persistence of LD phase between crossbreds (C) and purebreds,...

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...

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...

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...

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...

Single nucleotide polymorphisms for feed efficiency and performance in crossbred beef cattle

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...
