dc.description.abstractAbstract The objective was to thermally characterize the facilities during the growth and finishing phases of pigs and to evaluate the influence of climate control systems on the expression of the behaviors of pigs. The experiment was conducted at the Federal Rural University of Pernambuco, Serra Talhada, PE, Brazil, during the spring of 2019. Twenty-seven pigs aged 63 days were used. The animals were submitted to pens without climate control system, with forced ventilation, and with an evaporative adiabatic cooling system. Dry bulb temperature (°C), relative air humidity (%), black globe temperature (°C), and swine behavioral responses were recorded, submitted to multivariate analysis, using the principal component technique. Pens with the evaporative adiabatic cooling system showed a significant reduction in air temperature and an increase in relative air humidity, during the two phases. Pigs submitted to evaporative cooling showed greater ingestive activity and lethargic behavior, typical of the studied phases. Resumen El objetivo fue caracterizar térmicamente las instalaciones durante las fases de crecimiento y finalización de los cerdos y evaluar la influencia de los sistemas de control climático en la expresión de los comportamientos de los cerdos. El experimento se realizó en la Universidad Federal Rural de Pernambuco, Serra Talhada, PE, Brasil, durante la primavera de 2019. Se utilizaron 27 cerdos de 63 días. Los animales fueron sometidos a corrales sin sistema de climatización, con ventilación forzada y con sistema de enfriamiento adiabático evaporativo. Se registraron la temperatura de bulbo seco (° C), la humedad relativa del aire (%), la temperatura del globo negro (° C) y las respuestas de comportamiento de los cerdos, sometidas a análisis multivariante, utilizando la técnica de componentes principales. Los corrales con sistema de enfriamiento adiabático evaporativo mostraron una reducción significativa de la temperatura del aire y un aumento de la humedad relativa del aire, durante las dos fases. Los cerdos sometidos a enfriamiento evaporativo mostraron mayor actividad ingestiva y comportamiento letárgico, propio de las fases estudiadas.
