My research program is interested in optimizing the resilience of dairy herds in a context of climate change. My team is particularly interested in the response of dairy cows to heat stress, which is a relatively new topic in continental climatic conditions. In fact, we were the first to demonstrate the effects of heat stress in Quebec dairy herds. We continue to study the magnitude of the consequences of heat stress in dairy cows and their growing fetus while trying to understand the physiological mechanisms behind these consequences. In addition, we are working to develop environmental, nutritional and genetic strategies aimed at increasing the resilience of dairy cows to heat stress.
