title: A confinement respiration chamber for short gaseous exchange measurements.
abstract: The present work deals with the construction and function of a confinement chamber for small ruminants intended for use in short energy metabolism studies. CH4, CO2 and O2 are analysed according to physical principles. Several calibration tests of the whole system were carried out with satisfactory results. A close agreement has been observed when comparing the values of day-to-day variation heat production obtained by confinement and open-circuit calorimetry.
