What is the Temperature Humidity Index (THI)?
THI combines temperature and humidity into one practical stress signal. Dairy cows can experience significant heat stress from around 22°C when humidity pushes THI above 68 — often before the shed feels dangerously hot to people.

The Hidden Costs of Heat Stress.
Reduced Milk Yields
Heat stress can cost around 2.2kg of milk per cow daily — losses that compound fast across a full herd.
Crashing Fertility Rates
When cows are heat stressed, conception rates can fall from 25% to 7%, making climate control a reproduction issue too.
Increased Lameness
Cows stand longer to shed heat, increasing hoof pressure and raising the risk of lameness across the group.
