Description: Accurate estimates of heat and moisture loads are essential in the design of efficient and economic environmental control systems in farrowing houses. Five farrowing rooms were studied using whole-house calorimetry tech niques. Comparisons were made between batch and continuous far rowing regimes, and three flooring types. Thetotal heat load was found on average to be 1850 kJ/h for each sow and litter with 61, 60 and 51% of the total heat exhausted as latent heat for raised crates, crates with partly perforated floors, andcrates with fully perforated floors, respectively. Theresults of this study suggest that the recommended minimum ventilation rates should be increased. Some problems were observed in the designand management of the environmental control systems.
