Pigs

Pig farm in Taiwan, in 2020

For pigs, heat stress varies depending on their age and size. Young and growing pigs with the average body mass of 30 kg (66 lb) can tolerate temperatures up to 24 °C (75 °F) before starting to experience any heat stress, but after they have grown and are fattened to about 120 kg (260 lb), at which point they are considered ready for slaughter, their tolerance drops to just 20 °C (68 °F).
