Heat stress: Cost-effective cooling for outdoor dairy cows

A newly-published study demonstrates the effectiveness, both in cost and heat stress reduction, of extending cooling strategies for dairy cows throughout the day and night, with a novel outdoor use of ducted air systems that could be applied to outdoor herds with limited physical infrastructure. Heat stress is a major limiting factor in dairy production in tropical, sub-tropical and temperate climates during summer, presenting a significant risk to the sustainability of global dairy productio
