| Abstract The aim of the present research was to propose a bioclimatic mapping to classify the thermal comfort and discomfort of rural workers within the state of Minas Gerais, considering historical and future scenarios. Monthly historical series (1976-2014) of minimum, mean and maximum temperature-humidity index (THI), determined through the values of air temperature (minimum, mean and maximum) and relative humidity from 48 weather stations located in the state of Minas Gerais were used to analyze the trends through Mann-Kendall and linear regression assays. The bioclimatic mapping of human comfort, obtained via geostatistical analysis, was developed as a function of the minimum, medium and maximum THI for the historical period (1976-2014) and future... |

| Grazing animals are exposed to heat stress and there should be conditions to facilitate water intake. Three experiments were carried out to determine the relationship between water intake, water temperature, and heat stress for Holstein pastured dairy cows. Experiment 1: Drinking behavior of 13 cows was evaluated (for 3 consecutive days) and four time periods were established according to the temperature humidity index (THI): (H1:05:00 to 10:59 h, H2:11:00 to 16:59 h, H3:17:00 to 22:59 h, and H4:23:00 to 04:59 h). The highest mean percentage of drinking bouts (53.2%) was registered in H2 (THI: 74.91 to 83.95). Drinking bout means among time periods were different (p < 0.05), thus showing that heat stress conditions influence drinking behavior.... |

| O objetivo deste trabalho foi avaliar índices de conforto térmico em sistemas de integração lavoura-pecuária-floresta, com eucalipto em arranjos de 14x2m (ILPF-1) e de 22x2m (ILPF-2) e árvores nativas dispersas com 5 árvores/ha-1 (ILPF-3), no Município de Campo Grande, Mato Grosso do Sul. O experimento foi conduzido na Embrapa Gado de Corte, em Campo Grande, MS, de julho a setembro de 2013. As avaliações foram realizadas mensalmente, em quatro dias consecutivos, em três horários (09h00, 12h00 e 15h00; GMT -04h00). Foram determinadas a temperatura do ar (°C), temperatura de globo negro (°C), temperatura de bulbo úmido (°C), umidade relativa do ar (%) e velocidade do vento (m s-1). Foram calculados o Índice de Temperatura e Umidade (ITU), Índice de... |
