“…Studies to identify indicators of heat stress (e.g., Cross et al, 2018 ; Gourdine et al, 2019 ; Poullet et al, 2022 ) and those for predicting breeding values for heat tolerance using public weather data (e.g., Tiezzi et al, 2020 ; Usala et al, 2021 ; Zumbach et al, 2008 ) have also been performed. Thus, developing methodology to genetically improve pigs to cope with climate change would be valuable (e.g., Gourdine et al, 2021 ; Hara et al, 2022 ; Ogawa, Kimata, et al, 2022 ).…”
