1. Make sure the "normal" range for respiratory rates is high enough to cover those seen in heat stress.
2. Set the heat stress threshold wet bulb temperature higher than any scientifically proven levels.
3. Score all animals as having no heat stress regardless of respiratory rate, respiratory character, wet bulb temperature or clinical signs of heat stress.
Done and Dusted. Dont recognise it, dont report it, dont acknowledge it and ...bingo, dont have it. No heat stress. Simple.
