Meet Grégoy ( 60 second OAC video )

Dr. Grégoy Bédécarrats was born in France where he later pursued his undergraduate and master’s studies. He did his first research with poultry while working on his master’s, studying the effects of prolactin on incubation behaviour in turkey hens. After completing a PhD at McGill University, he did three years of post-doc work at Harvard Medical School studying the molecular mechanisms controlling human reproduction. In 2003, he returned to Canada and joined the University of Guelph.

As well as his research, Grégoy is actively involved in undergraduate training, teaching and curriculum development. He mentors the University of Guelph Poultry Club which, among many other industry-related activities, maintains and breeds the heritage “Shaver lines” of chickens given to the university by Dr. Donald Shaver. He has held several editorial position in multiple scientific journals.

Research Impact

Grégoy’s main research interests focus on improving the reproductive efficiency of domestic birds, with the goal of finding a better balance between production parameters, health, welfare and the environment. His studies seek to determine the mechanisms affecting reproduction, especially at the brain-pituitary gland level. Based on his basic fundamental work, he has proposed a new model to describe the activation of the reproductive axis in chickens and has developed a new lighting system for poultry based on his research on spectrum lighting. These LED light bulbs are commercially available (www.Agrilux.ca) and are increasingly being used by commercial farms across Canada. In a nut shell, his and others research demonstrated that a 60 percent red light bulb promotes egg production in layers while the 60 percent green light promotes growth and weight gain in birds raised to be eaten (broilers). Beyond lighting, his recent research focused on the metabolic triggers that can independently initiate sexual maturation in chickens in an effort to better coordinate growth trajectory with photoperiod under industry settings.

Current Research Projects

Grégoy's current research focusses on expanding his study of spectrum lighting to turkey breeder hens, to improve reproductive capacity. He is also involved in studying the impact of body weight, age and strain on keel bone health and sexual maturity in layer pullets raised in cage-free housing systems. The knowledge gained will help better manage chicks and pullets to improve efficiency as well as birds’ health and welfare.

Graduate Student Information

Grégoy recognizes that graduate students need different types of support in their work and he tries to be flexible. While he likes to put students in charge of their own projects, he finds that some are ready to be more autonomous and others need more assistance, at least initially. Grégoy encourages his students to attend at least one international science meeting per year, and to present their work and publish as much as possible. He also works with undergraduates interested in doing research projects with similar expectations. Most have moved on to higher education and many have gone on to significant positions in the livestock industry.
