U of G researchers investigate the effects of postpartum health on estrus detection by activity monitors
Like people using fitness trackers, more and more dairy farmers are using automated activity monitors as an important part of herd reproductive management. Dr. Stephen LeBlanc, a professor at the Ontario Veterinary College, and PhD candidate and Dairy Farmers of Ontario (DFO) doctoral scholar Tony Bruinjé studied more than 1,300 cows in two commercial dairy herds to investigate the link between a cow’s post-partum health and the likelihood of detecting estrus by activity monitors for first breeding.
