^aT_Vall: all measures (every 10 min) of vaginal temperatures (°C); T_V4days: average of the six records per hour corresponding to 08:00, 12:00, 16:00, and 20:00 h during four days (°C); T_ES: ear skin temperature (°C); T_SS: shoulder skin temperature (°C); T_RS: rump skin temperature (°C); T_TS: tail skin temperature (°C); RR: respiration rate (breaths per minute). Data collection protocols have been described in Johnson et al. [68].
