RESUMO
The objective of this study was to determine thermal comfort ranges, as evaluated by air temperature and black-glove temperature and humidity index (BGTHI), for starter meat-type quails. Nine hundred quails were randomly distributed into five environmental chambers. Each chamber was programmed to provide different temperatures weekly. The following thermal environments were provided: SC - severe cold, MC - moderate cold, TC - recommended comfort environment, MH - moderate heat, and SH - severe heat. The best live performance was obtained when quails were submitted to temperatures of 36-39 ºC and BGTHI of 87.1 ± 0.4 and 91.4 ± 0.6 during the first week of rearing. Temperatures of 27-30 ºC and BGTHI of 75.8 ± 0.4 and 79.9 ± 0.6, during the second week, and temperature of 24 ºC and BGTHI of 70.8 ± 0.5 during the third week of rearing.
