Description
Denryter and colleagues tracked the vital signs of eight hand-reared caribou calves every day, from birth to 23 weeks of age. They built baseline health numbers for a species in decline across much of North America. Captive rearing supports caribou conservation and research, yet caretakers have had little published data on what normal temperature, heart rate, and breathing look like in young calves.
Healthy calves averaged 89 heartbeats per minute and 19 breaths per minute. Body temperature held near 38.9 degrees Celsius across the whole study period. All three measures fell as calves grew older and heavier, and age predicted those changes better than body mass did. When body temperature rose, calves compensated by breathing faster and raising heart rate. The authors offer that response as a reference for spotting illness early in captive herds.
