Heat abatement through cooling systems, shade, and management changes is increasingly important for livestock welfare as climate change brings more frequent and intense heat events.
Heat abatement is a welfare requirement that is becoming more urgent as climate change increases the frequency and severity of heat events affecting livestock globally. For dairy cows, which generate substantial metabolic heat from milk synthesis, even moderate temperature rises cause measurable welfare and productivity impacts. Effective heat abatement combines shade or shelter provision, mechanical cooling through fans and sprinklers, water access for drinking, and management changes including moving feeding to cooler parts of the day. Farms that invest in heat abatement infrastructure demonstrate both welfare commitment and economic pragmatism, as the productivity benefits of keeping cows cooler typically outweigh the infrastructure costs.
