摘要: Hoop structures have been used quite widely for animal production in the U.S. due to their lower capital costs and multi-purpose versatility. Hoop barns for grower-finisher (G-F) swine production have attracted attention in China as all alternative, environmentally friendly, and water-saving production system. This study was conducted to assess concentrations and emissions of ammonia (NH(3)) and greenhouse gases (GHGs) for a hoop G-F pig barn at a commercial pig operation in suburban Beijing, China. The NH(3) and GHG concentrations and emissions of the facility were measured for three consecutive days during spring and summer seasons. The results revealed the following hourly gaseous concentrations (mean +/- SD, mg m(-3)): 5.9 +/- 2.7 NH(3), 2,183 +/- 1,376 CO(2), and 4.0 +/- 2.5 CH(4) in spring, and 6.8 +/- 3.4 NH(3), 1,530 +/- 364 CO(2), and 5.0 +/- 23 CH(4) in slimmer. The estimated gaseous emissions averaged, in g pig(-1) d(-1), 22.7 NH(3), 2,003 CO(2), and 6.7 CH(4), or in g AU(-1) d(-1) (AU = 500 kg), 124 NH(3), 11,264 CO(2), and 36.2 CH(4). The emission values from this study, while being generally comparable with those reported in the literature, add new, information concerning emissions front alternative swine housing system.
