Livestock Temperature Stress Calculator

Disclaimer: Thresholds and recommendations based on official UK guidance. Cattle, sheep and pigs: AHDB and NADIS. Poultry: DEFRA Code of Practice for the Welfare of Laying Hens and Pullets, Code of Practice for the Welfare of Meat Chickens, and PB 10543 Heat Stress in Poultry. Individual animal responses vary by breed, age, condition, acclimatisation and housing. Housed poultry welfare depends primarily on in-house management; outdoor ambient temperature is a guide to ventilation load, not a direct indicator of bird body temperature. Always monitor animals directly and consult your veterinarian if concerned.
