PhD in Animal Biosciences (Thesis/Research)
Discover new knowledge and advance animal science.
The PhD in Animal Biosciences is offered through our Department of Animal Biosciences, a research-intensive department focused on Animal Breeding and Genetics, Animal Nutrition and Metabolism, Animal Physiology, and Animal Behaviour and Welfare. Graduate students can also conduct research as part of three collaborative programs with other departments: Bioinformatics, Neuroscience, and Toxicology.
Regardless of your specialization, you will learn through "hands on" experiential research opportunities with your faculty advisor and focus on your species of interest: dairy and beef cattle, laying hens, dogs and cats, zoo animals, horses, or laboratory animals, such as mice and rats.
Publish research
PhD Animal Biosciences students publish on average one paper per year and present at conferences at least once annually.
