Abstract
The objective of this study was to evaluate the effect of climatic conditions provided by two types of stalls on the physiological and behavioral responses of horses during agricultural exposure. The study was developed during 2014 and 2015 in an Agricultural Fair located in the semiarid region of the state of Minas Gerais, Brazil. Climatic environment, place of accommodation, physiological and behavioral variables of 114 Mangalarga Marchador horses, housed in individual metal and masonry stalls, were observed. Meteorological variables inside the metal and masonry stalls were monitored. Physiological variables were characterized by respiratory rate and body temperature. For behavioral analysis, the frequency of occurrence of defecation, urination, neigh, agitation, food and water intake were observed at 8 am, 10 am, 12 pm, 14 pm, 16 pm and 18 pm. The thermal environment was classified as thermal discomfort from 10 am. Respiratory rate and body temperature were outside ideal values. The metal stall caused greater thermal discomfort for horses.

RESUMO Objetivou-se avaliar o efeito das condições climáticas proporcionado por dois tipos de baias sobre as respostas fisiológicas e comportamentais de equinos por ocasião de exposição agropecuária. Foi observado o ambiente climático, local de acomodação, variáveis fisiológicas e comportamentais de 114 equinos da raça Mangalarga Marchador, alojados em baias individuais de metal e alvenaria. Foram monitoradas as variáveis meteorológicas no interior das baias de metal e de alvenaria. As variáveis fisiológicas foram caracterizadas por meio da frequência respiratória e temperatura corporal. O ambiente térmico foi classificado como de desconforto térmico a partir das 10 h. A frequência respiratória e a temperatura corporal estiveram fora dos valores considerados ideais. A baia de metal proporcionou maior desconforto térmico para os equinos.
