The homogeneity of the ambient temperature is a great influence factor on the thermal comfort conditions in zootechnical installations as well as the correct orientation in their installation, they allow the animals a greater level of thermal comfort and greater productivity. In this way, this work sought to evaluate, through temperature sensors, the thermal environment of the experimental swine shed in relation to the temperature distribution inside the shed, the influence of the location on the temperature distribution, pigs thermoneutrality zone. The influences of the experimental shed at room temperature during three periods (07:00, 12:00 and 17:00 hours) of the day were analyzed by means of temperature sensors (Treatment 1, 2, 3 and 4) arranged along the shed had 32 experimental bays. There was no significant difference between the treatments and the periods. The bays located in treatment 3 and 4 presented the highest temperature values due to their geographic location (Northeast), which received the highest solar radiation loads during the day. Regardless of the treatment, the period of 12h (noon) presented the highest mean temperature. Although in the period of 07 and 17 hours the temperatures of the animals did not reach the critical temperature of thermal comfort (32º), in the period of 12 h the temperatures reached close to the critical temperature, being necessary the use of artificial systems of control of the environment , such as fans and nebulizers.
