Feedlot cattle in the United States and globally are exposed to summer heat that causes significant welfare compromise. Shade provision and cooling systems are demonstrably effective but rarely required by law.
Feedlot heat welfare is a case where the evidence for both the problem and the solution is clear but regulatory action is absent. Cattle exposed to summer heat without shade experience physiological stress that suppresses immune function, reduces growth, and in extreme events causes death. Shade provision and cooling systems reduce all of these outcomes while providing measurable production benefits. The economic case for shade aligns with the welfare case. What is missing is the regulatory requirement that would ensure universal adoption rather than leaving it to individual producer discretion. Consumer pressure through welfare certification demands provides one lever; regulatory advocacy provides another.
