Finding My Interests
While pursuing my general undergraduate science degree, I developed specific interests in the fields of animal physiology and mathematics, and became focused on gaining as much knowledge and skills in these areas as I could. Through these interests, as well as past experiences in livestock agriculture, I recognized my desire to pursue an MSc thesis project that integrated the study of reproductive physiology and multivariate statistics or bioinformatics. This lead me to study at the University of Guelph in the Animal Biosciences department with Dr. Julang Li and work alongside Sudhanshu Sudan, Xiaoshu Zhan, Renée Hilker and Serena Dingle.
As an MSc candidate, my thesis project is focused on applying metabolomics to identify biomarkers (biological indicators of a phenotypic state) for the current or future reproductive performance of sows and gilts (young female pigs). North American pork operations heavily rely on genetics when selecting gilts for the breeding herd. However, the heritability of many important reproductive parameters, such as litter size, is poor, reducing selection efficiency and negatively impacting economic profit and pig welfare. I am in the process of screening urine, saliva and serum samples collected from gilts and sows at Arkell Swine Research Station for the concentration of a variety of reproductively relevant metabolites (amino acids, hormones, vitamins, lipids, etc.). Using a multivariate statistics workflow applied using Metaboanalyst and machine learning techniques, I hope to identify metabolites and metabolic processes that are altered between sows or gilts of high reproductive potential and low reproductive potential (defined by the average number of piglets born alive per litter). If the metabolites identified in this comparison can then be applied to a test set of samples and accurately predict sow and gilt reproductive potential, the next step is to develop a method in which they can be integrated into gilt selection protocols to improve their efficiency.
