Cost-effective cooling for outdoor cows

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