Animal cognition and animal personality: Individual differences in exploratory behaviour, learning, vocal output, and hormonal response in an avian model
DownloadFall 2012
The foremost goal of this thesis is to integrate the study of animal cognition with the field of animal personality. In the early 20th century, Pavlov integrated these fields by describing an interaction between associative learning and dogs that exhibited different behavioural types. Since...

Fall 2021
The field of animal personality, the study of adaptive among-individual behavioural differences in animal populations, has both exploded in popularity in the last few decades and come under heavy scrutiny by behavioural ecologists. The sudden interest in the field stems from the widespread...

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...

Consumer preferences for the genomic selection for particular traits in breeding dairy cows in Canada
DownloadSpring 2022
This study examines Canadian public preferences for the use of genomic selection in breeding dairy cows for four main traits– feed efficiency, methane emission reduction, enhanced disease resilience, improved cow fertility as well as the use of antibiotics. Since this research information might...

Does fluctuating selection maintain variation in nest defense behavior in Arctic peregrine falcons (Falco peregrinus tundrius)?
DownloadFall 2021
Within populations, individuals often exhibit repeatable among-individual differences in behavior, and in some cases, these are linked to different fitness outcomes. Several mechanisms have been proposed to contribute to the maintenance of repeatable among-individual variation in behavior. Here...

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),...

Disease resilience is defined as an animal’s ability to maintain a high level of performance in the face of disease challenges caused by multiple pathogens, as is often the case in commercial pig farms. Therefore, disease resilience is anticipated to be critical to the profitability of the pig...

Goonewardene, L. A., Wang, Z., Yang, R. C., Huedepohl, C.
Data from the Alberta Agriculture Food and Rural Development data base, which keeps inventories of elk producers and velvet production information (n = 12 724), were used to estimate genetic and phenotypic variances, heritability and repeatability estimates for velvet antler using REML methods....

Genetic and genomic basis of antibody response to porcine reproductive and respiratory syndrome (PRRS) in gilts and sows
Download2016-01-01
Serao, Nick V. L., Kemp, Robert A., Mote, Benny E., Willson, Philip, Harding, John C. S., Bishop, Stephen C., Plastow, Graham S., Dekkers, Jack C. M.
Background:Our recent research showed that antibody response to porcine reproductive and respiratory syn-drome (PRRS), measured as sample-to-positive (S/P) ratio, is highly heritable and has a high genetic correlation with reproductive performance during a PRRS outbreak. Two major quantitative...
