Zootecnia de precisão aplicada ao comportamento bioclimático de matrizes suínas gestantes.

Abstract

This study evaluated different housing systems for pregnant sows aiming to describe quantitative and qualitative aspects of environment. The work approaches the variables that influence the production system, with determination of the favorable conditions to the best animal production. Trial was carried in the summer of 2005 in a farm specialized in industrial production of pork, located in Elias Fausto City, São Paulo State, Brazil. In gestation facility 24 gilts were allocated: 12 in individual stalls (T1) and 12 in group housing (T2). Metheorological and environmental variables indicated the confinement system in group-houses as that associated with better natural thermal monitoring for pregnant gilts. Behavior evaluation showed lower incidence of stereotypies on group housing system. In relation to concentration of gases, mean levels did not exceed the concentrations considered limitating for sows.
