Effect of Slatted Floor Configuration on Air Quality and Floor Cleanliness in Sow Gestation Rooms

Authors: Yan, Xiaojie; Zhang, Qiang; Connor, Laurie
Description: This study was part of a larger investigation of the effects of slat to slot ratio of slatted concrete floor on sow comfort and indoor environment for group housed gestating sows. Based on kinematic tests, two different designs of concrete slatted floor were installed in two gestation rooms: room #1 with 105 mm wide slats and 19 mm slots; and room #2 with 125 mm wide slats and 25 mm slots. The purpose of this paper was to compare air quality between these two different floor designs. Temperature and relative humidity were recorded continuously in each room for 9 weeks (test period) during each of two sow gestation periods. Ammonia concentrations were measured as an air quality indicator. Time-lapse cameras in each room took pictures of the pen floor hourly every Tuesday during the test periods, and the pictures were then analyzed to assess the cleanliness of the floors. Preliminary results showed that there were no significant differences in ammonia concentration and cleanliness of the floors between the two slat designs. The two floor configurations had the same performance in terms of manure drainage and air quality (ammonia level).
