Description: An earth tube heat exchanger was coupled with a slotted air inlet in three rooms of a growing-finishing swine building. A slotted air inlet provided fresh outside air to three other rooms without heating. Exchangers 1,2, and 3 consisted of three, four, and four pipes of 0.3 mdiameter non-perforated plastic drainage pipes, respectively. Each line was 61 m long and buried at 3 m depth. The air temperature, relative humidity, and ventilation rate of each room were measured betweenJanuary 18, 1990 and February 14, 1991. Growth perform ance and health of pigs were also evaluated. For different combinations of outside air temperature and pig mass, there was no significant effect of the exchanger on ventilation rate compared to the conventional system. Pneumonia lesions, atrophic rhinitis de grees, and growth performance of pigs were not affected by use of theexchanger. In this study, no difference was observed between the two ventilation systems. The construction and use of similar earth tube heat exchanger is therefore not recommended in regions with equivalentenergy costs and climatic conditions tojhat of Quebec.
