Description: Moisture as water vapor is generated within total confinement livestock buildings by evaporation from lungs and skin of the animals, floor surfaces, waterers, and animal wastes. Aeration of liquid wastes also may contribute to the total moisture production (5). The control of this moisture in the atmosphere of a livestock building is a primary function of ventilation. Moisture production values for various classes of livestock for ventilation design purposes are available (1, 2). Such design criteria, however, do not indicate the extent to which values are influenced by the system of housing selected or by the manure-handling method chosen. The importance of such factors has been demonstrated by Harman et al. (4) with regard to pig housing but whether these factors are also significant in total confinement beef units does not appear to have been investigated. The main objective of the study reported here was to ascertain the effects on moisture removal of two such housing systems, viz, fully slatted and straw-bedded systems. Also included in the study was an investigation into the effects on the moisture removal rate of removing the exhaust air at high and low levels for each system and of opera ting aeration rotors below the slatted floor.
