Odour and greenhouse gas (GHG) emissions were measured on two 3000-sow farrowing
\noperations to quantify the relative and absolute contributions to odour and greenhouse gas
\nemissions from hog barns and manure storage structures; to characterize these emissions; and to
\ndevelop or validate models which were capable of confidently predicting the dispersion of odour
\nfrom hog operations in surrounding communities. The two farrowing operations (Farm A and
\nFarm B) were built from the same blueprint with slight modifications – Farm A had an extra
\nquarantine room at the east end of the building. The buildings on both farms were mechanically
\nventilated with wall mounted exhaust fans. Manure was stored as liquid in under-floor shallow
\ngutters and then removed to outdoor earthen manure storage (EMS). The major difference
\nbetween the two operations was that Farm A had a two-cell EMS with negative pressure covers
\n(NPC); whereas Farm B had an open single cell EMS. It was found that odour emission from farrowing rooms was 2 to 3 times higher than that
\nfrom gestation rooms on the two farms. The average odour emission rate of the two farms was
\n22.9 OU\/s-m2 (314 OU\/s-AU) from farrowing rooms and 9.6 OU\/s-m2 (113 OU\/s-AU) from
\ngestation rooms. There was no statistically significant (P>0.05) difference between the two
\nfarms in emission rate from farrowing rooms; however, the emission rate from gestation rooms
\non Farm A was significantly (P<0.05) higher than that on Farm B. Outdoor temperature had the\nmost influence on odour emission from building exhaust. Specifically, the odour emission rate at\nlower temperatures (<14\u00b0C) was significantly lower than that in higher temperature ranges (15-\n30\u00b0C). The open EMS contributed 60% to the total odour emission on Farm B; whereas the NPC EMS\ncontributed only 2% to the total odour emission on Farm A.\n<\/p>\n","protected":false},"excerpt":{"rendered":"
