frostbite

injury to tissues due to exposure to extreme cold. Not a common occurrence in free-living animals in the wild but is observed in poorly housed captive animals and birds. May cause whole-body freezing or gangrene of extremities including deer antlers. Deer forms are probably the most susceptible animals. Gangrene of the extremities, especially in pigs, and of the comb in chickens does occur in the domestic species but only if they are in poor condition and are caught outside in a storm.
