Temperature–humidity index (THI) Britannica
Web13 Aug 2024 · Barn temperature and humidity index (THI) was detected at 2:00 p.m. (Sengar et al. 2024), as an indicator of heat-stressed condition. Average THI was calculated by the equation, THI = 0.72 (Tc + Tw) + 40.6 (Tc, dry bulb temperature; Tw, humidity bulb temperature) (Buzan et al. 2015). Web8 Nov 2024 · The temperature-humidity index (THI), representing the combined effects of environment temperature (°C) and relative humidity (%), is widely used to measure the impact of heat stress on dairy cattle. A negative correlation exists in cattle on reproduction traits when the THI crosses a threshold level. low sex drive and ed
