Analysis of Odorous Compounds in Swine Buildings and Their Relationship to Thermal Environment, Management and Categories of Pigs

摘要

The objective of the study described in this paper was to develop a method to examine the key odorants (KOs) that can be used to study the effects of the thermal environment, the management and the animal categories on odor emission in swine buildings. The study has included winter and summer surveys at four different swine herds equipped with gestation, farrowing, rearing and finishing buildings. The winter survey was carried out during the winter of 2003/04, and the summer survey was carried out inthe summer of 2004. Odorous compounds (odorants) in the buildings were sampled by use of the solid-phase micro-extraction (SPME) technique and analyzed by gas chromatography and mass spectrometry (GC/MS). The study included the following five key odoran
