In the UK, daily temperatures during spring and summer can fluctuate up to 12°C but relative humidity doesn’t fall below 60% which is seen as the heat stress ‘trigger level’ on THI scales. This means that cows are almost always under heat stress conditions.
As temperatures rise fertility is always the first performance measure to be affected. Fluctuating temperatures in spring and summer (14-22°C) cause 20% of cows to slip a cycle, costing £84 per cow affected.
