Siestas for cows: UK farmers seek new ways for cattle to beat the heat

A growing number of UK farmers are considering adapting their farms to protect animals against heat stress, and among the new measures is the idea of indoor “siestas” for cows that may normally be grazing outdoors in summer.

Heat stress is a major issue for cattle, especially modern dairy cows, which can produce 10-15% less milk in hotter temperatures. It can also effect their fertility and increase the chances of early pregnancy losses.
