Investigating the genetic basis of boldness and reproductive performance traits in the grey seal (Halichoerus grypus)
DownloadSpring 2022
Individual variation provides the material for natural selection to act upon, influencing ecological and evolutionary processes. Much phenotypic variation in traits, such as behaviour and life-history, have a moderate to high heritable component, suggesting that these traits may have adaptive...

Relationship between trained sensory and objective measured meat quality attributes in crossbred Canadian beef cattle after 3- and 29-days post-mortem aging
DownloadSpring 2022
Meat quality attributes are pivotal for the beef industry. Studies across Canada showed major beef quality concerns originate from inconsistency of palatability attributes. To improve these traits genetically, they should be standardly measured, their (co)variance components and genetic...

Genomic Analysis of IgG Antibody Response to Common Pathogens in Commercial Sows in Health-Challenged Herds
Download2020-10-23
Sanglard, Leticia P., PigGen Canada, Mote, Benny E., Willson, Philip, Harding, John C. S., Plastow, Graham S., Dekkers, Jack C. M., Serao, Nick V. L.
Losses due to infectious diseases are one of the main factors affecting productivity in the swine industry, motivating the investigation of disease resilience-related traits for genetic selection. However, these traits are not expected to be expressed in the nucleus herds, where selection is...

Spring 2019
A reproductive phenotype that has high variability, repeatability, heritability, and association with fertility could become an excellent candidate for genetic selection to augment fertility in dairy cows. Therefore, the general objective of this research was to evaluate the aforementioned...

Trade-offs between wood density and radial growth in the Region H white spruce Controlled Parentage Program, Alberta, Canada
DownloadFall 2019
Trade-offs between wood density and radial growth rate in white spruce were investigated. Decreases in wood density associated with increased radial growth rate have been well documented in several tree species, including white spruce (Picea glauca (Moench) Voss)....

Polar bears (Ursus maritimus) were among the first large mammals to be assessed for genetic variation in the wild, and they remain a common subject of genetics studies. Although recent advances in genotyping technology have allowed for more accurate determination of population structure and the...

Genomic selection for pork quality and carcass traits in both cross- and pure-bred populations
DownloadSpring 2015
Pork quality and carcass characteristics are now being integrated into swine breeding objectives because of their economic value. Understanding the genetic basis for these traits is necessary for this to be accomplished. The main objective of this study was to improve pork quality traits in two...

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),...

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...

Breast cancer is the most common cancer among women in the developed world. The disease results from the combined effects of genetic, environmental, reproductive and lifestyle risk factors. Germline DNA variations identified thus far by linkage and genome-wide association studies (GWASs) account...
