Avaliação do conforto térmico e comportamento de leitões influenciado por diferentes sistemas de aquecimento

Abstract

The aim of this work was to evaluate the effect of different shelter heating system types on thermal comfort and piglets’ behavior. This work was carried out at the swine maternity on the Experimental Center on Swine Industry of Federal University of Lavras, from October to November of 2015. A solar prototype water heater was built using alternative materials - SASA, which was compared to three other heating systems (conventional solar water heater - SASC, infrared lamps - SALI and concrete floor heating by means of electrical resistance (SAEL)) Based on the results, it was concluded that the four tested heating systems in the shelters were deficient in the adequate temperature for the three weeks of piglets’ life and about the behavior inside the shelter the one that presented highest frequency was “walking”
