Abstract: Impact of ground channel airflow designed house was investigated on internal environment, gaseous emissions and energy cost of pig houses during Winter season. In the present experiment, impact of ground channel airflow (with ground level heating system) Designed house (GCA) was compared with conventional mechanical airflow (with halogen lamp heating) designed house (MA). Experimental houses consisted of MA with gestating sows (MA1), lactating sows (MA2) and finishing pigs (MA3) and GCA with gestating sows (GCA1), lactating sows (GCA2) and finishing pigs (GCA3). Result elucidated that, internal temperature in MA and GCA were in general requirements for gestating and finishing pig houses (GCA1 vs. MA1; GCA3 vs. MA3) except lower value was found in lactating sow house GCA2 in comparison to MA2. Although there was found significant differences in GCA2 and GCA3 relative to MA2 and MA3, respectively, relative humidity for both houses were in suitable range (50-90%). Emissions of CO from slurry were significantly lower for GCA2 (20%) 2 and GCA3 (9%) than MA2 and MA3, respectively. Ammonia concentration was around 30% repressed in GCA1-GCA3 in comparison to MA1-MA3, respectively. Energy consumption, energy cost and equivalent CO2 emissions from energy use were significantly down trended (around 62%) in all GCA than MA. Overall, Ground channel airflow designed house was found effective (for Winter season) in reducing gaseous concentrations (CO2 and NH3 ) and minimizing energy cost without adverse impact on the internal animal 2 3 environment.
