Technology solutions for cattle heat stress including cooling systems, shade structures, and genetic selection for heat tolerance are increasingly important welfare interventions as global temperatures rise.
Heat stress in dairy cattle causes prolonged physiological suffering including elevated respiration rate, reduced feed intake, and impaired reproductive function over the hottest months of the year. In extreme events, heat stroke can be fatal. The good news is that effective cooling technologies are available and economically justified even by production metrics alone. Climate change makes investment in heat abatement infrastructure increasingly urgent from both welfare and economic perspectives. Supporting producer adoption through welfare certification, subsidies, and technical assistance accelerates the welfare improvement.
