| Resumen en inglés | The objective with this study was to estimate the voluntary feed intake (VFI) of sows during the occurrence of heat waves in the Triângulo Mineiro and Alto Paranaíba mesoregion, Minas Gerais, Brazil. The Instituto Nacional de Meteorologia (INMET) database was used to calculate the temperature-humidity index (THI) from 2008 to 2017 for Araxá, Frutal, Ituiutaba, Patos de Minas, Patrocínio, Uberaba, and Uberlândia, and the estimated VFI with and without effective occurrence of heat waves (EOH). An economic estimation of the revenue based on the VFI was performed. The data were analyzed by Friedman's non-parametric test (two-way non parametric analysis), using the significance level of 5%. The sows raised in Patrocínio showed a higher average prediction of VFI (6.611 kg without EOH and 5.743 kg with EOH) than Ituiutaba (6.424 kg without EOH and 3.969 kg with EOH) and Frutal (5.868 kg without EOH and 4.648 kg with EOH). In the classification “without EOH”, the microregions of Araxá (6.502 kg), Uberaba (6.452 kg), and Uberlândia (6.478 kg) did not differ from the other cities, but “with EOH”, Araxá (4.864 kg) differed from Patrocínio (5.743 kg). The reduction of VFI due to thermal stress represented a revenue reduction of R$ 74.60 per litter. The averages for predicted VFI were lower in the EOH category than in the probable occurrences of heat waves category for all cities. The predominance of heat waves reduces the VFI of sows, particularly in Ituiutaba and Frutal |
