Veterinarians at the Connaught Medical Research Laboratories, 1931-72.

This study traces the changing mission of the University of Toronto's Connaught Medical Research Laboratories regarding the health of animals. We argue that the early work of Connaught's veterinarians in the 1930s and 1940s focused on the care for experimental animals as well as lending veterinary knowledge to problems in human medicine and public health. This gave way to a more direct focus on veterinary products after the Second World War. Connaught was motivated to enter the veterinary field in part to capitalize upon the growing market for veterinary medicines. It met with mixed success in this endeavour. Work was initially focused on livestock medicines and later expanded into products for companion animals, reflecting broader shifts in the veterinary profession and the economic value of animals during the 20th century.
