| Abstract | This study was conducted to compare the heating effects of the geothermal heat pump (GHP) and traditional heating system (heating lamps) in the pig barn. A GHP system was installed at a pig farm to examine the effects on the growth performance, temperature, greenhouse gas emissions (CO2), noxious gas emissions (NH3 and H2S) and energy savings. A total of 20 piglets having an initial body weight of 6.95 ? 0.5 kg were randomly divided into two identical pig barns for 8 weeks. The temperature inside the pig barn was significantly increased in the GHP-installed pig barn (P < 0.05). Similarly, the outflow temperature from the heat pump was higher (P < 0.05) than the inflow temperature. The NH3 concentration, H2S concentration and CO2 concentration were decreased significantly (P < 0.05) in the GHP-installed pig barn relative to the control. Furthermore, electricity consumption was also reduced by heating the pig barn with a GHP system as compared to the traditional heating system. These results show that the GHP system can be used as an alternative and eco-friendly energy source in pig barns without having an adverse effect on growth performance. |
