No effect of drinking water temperature (ambient vs. chilled) on consumption of water during hot summer weather in ponies

    Consumption of ambient warm (17-31C) vs. ice-chilled (0- 1C) drinking water was compared in a within-subjects cross-over trial using nine mature pony stallions housed in tie-stalls during hot summer weather (15-29C). Ponies drank similar quantities whether provided warm water or chilled water. This is in contrast to earlier reported findings that during cold winter ponies drank more if provided warm water than if provided cold water. There were no qualitative differences in drinking behaviour owing to water temperature.
