Temperature and humidity both play a role in thermal stress. Using the Temperature Humidity Index (THI) enables you to determine the level of summer stress on dairy cows. The Thermo Neutral Zone for dairy cows is 5-20°C, stress symptoms begin at a THI of 68; temperature of 24° and a relative humidity of 20 per cent. With the UK average humidity over 70 per cent, the heat stress threshold is reached at temperatures as low as 22°C.
