The present experiment was carried out on healthy yaks maintained under semi range system of management belonging to different age groups and body weights at the NRC on Yak, Arunachal Pradesh, India. The physiological responses were recorded in morning and evening at fortnightly interval along with ambient temperature and relative humidity round the year. The temperature humidity index used for cattle was suitably modified for yaks.Yaks are comfortable at THI of 52. The heat load or heat stress was experienced by yaks when THI exceeds 52. The yaks were subjected to heat stress when the THI was above 52 as indicated by increased physiological responses.
