what rate does a horse's heart beat per minute
Normal adult horses have a heart rate of 28 to 40 beats per minute. Newborn foalsâ heart rates range from 80 to 120, older foals from 60 to 80, and yearlings from 40 to 60 beats per minute.To determine an accurate heart rate,owever, in a fit horse the rate should decline to 40 or 50 breaths per minute within 10 or 15 minutes. The ratio of heart rate to respiration rate in horses is usually about 4:1. That is, the heart beats 4 times for each breath the horse takes.
