Avaliação térmica ambiental de uma instalação com lanternim para suínos em fase de crescimento e terminação.

Abstract

The aim of this work was to study the environmental thermal conditions in two different systems of thermal conditioning for swine housing in growth and finishing periods. The following treatments were used: room with chimney (WC) and room without modification (no chimney) (NC). A completely randomized experimental design was used in factorial 2 x 9 (two treatments and nine schedules) with eleven repetions for each treatment. Three hundred and thirty six crossed gilts (Landrace x Large White) were used. The gilts were distributed among 24 stalls wich were monitored. In this study the global temperature and humidity index (GTHI), radiant thermal load (RTL), and relative air humidity (RU) were estimated. The treatments WC and NC provided similar environmental thermal. Therefore the chiminey construction in old building for growth and finishing pig was not able to provide environmental more ventilated and more appropriate to the animals in Summer.
