High-producing lactating cows and heat stress

Researchers have investigated the impact of heat stress in Australian dairy cows grazing summer pastures, seeing high temperatures and humidity leading to a significant drop in milk production – but this can be rectified. Led by The University of Melbourne and Ghana, researchers at the Faculty of Veterinary and Agricultural Sciences investigated the effect of summer heat on lactating Holstein Friesian cows at the university’s robotic milking farm in Dookie, Victoria, Australia.
