The calves were housed in individual polyethylene hutches (Poly Square Calf Nursery, Agri-Plastics, Grassie, Ontario, Canada). Each calf was tethered with a chain lead and had access to the outdoors. The hutches were located on a gravel base and the interiors of the hutches were bedded with wood shavings. Hutch placement prevented physical contact between the calves, but allowed visual and auditory contact. Ambient maximum temperature and relative humidity were recorded daily using a calibrated thermohygrometer (Digital Relative Humidity/Temperature Meter with Minimum/Maximum Memory, Fisher Scientific Company, Ottawa, Canada). The management conditions to which the calves were exposed were representative of commercial dairy operations in Ontario, and were in accordance with the policies and guidelines of the Canadian Council on Animal Care.
