When temperatures rise, it's not just the heat that impacts dairy cowsโhumidity plays a major role too.
That's where the Temperature Humidity Index (THI) comes in. THI combines temperature and humidity into a single measurement that helps identify when cows begin experiencing heat stress. Even before visible signs appear, elevated THI levels can lead to reduced feed intake, lower milk production, decreased reproductive performance, and overall herd discomfort.
Understanding THI allows producers to take proactive steps with ventilation, air movement, and cooling strategies before heat stress impacts herd performance.
Because when it comes to dairy production, managing the environment isn't just about comfortโit's about protecting productivity.
