Heat stress in livestock can lead to lower milk quality, with reduced protein and fat content, and thinner eggshells, increasing the risk of breakage during transport and storage. These changes can affect production efficiency and increase costs for farmers. While consumer demand for milk and eggs remains largely unaffected, extreme heat events can result in higher mortality rates and reduced productivity, posing risks to the agricultural supply chain. The severity of these impacts depends on the intensity of heatwaves and the effectiveness of mitigation measures.
