dc.description.abstract <p>The effect of ventilation rate (VR) on ammonia and greenhouse gas emissions from co-composting dead hens mixed with hen manure was quantified. Three VR levels of 0.9, 0.7, and 0.5 m<sup>3</sup> h<sup>-1</sup> were evaluated. Gaseous concentrations were measured using a multi-gas infrared photoacoustic analyzer, VR was measured with flowmeters, and the gas emission rate was computed from the VR and gas concentration. Decomposition of the carcasses over the 11-week composting period was greater than 88%. VR was found to significantly affect NH<sub>3</sub>, CO<sub>2</sub>, and CH<sub>4</sub> emissions (p < 0.05). Specifically, cumulative emissions per kg of initial matter for VR of 0.9, 0.7, and 0.5 m<sup>3</sup> h<sup>-1</sup> were, respectively, 2.4, 2.0, and 1.2 g NH<sub>3</sub>; 78, 66, and 42 g CO<sub>2</sub>; 120, 90, and 52 mg CH<sub>4</sub>; and 6.4, 6.1, and 5.1 mg N<sub>2</sub>O. Hence, the study results suggest that the ventilation rate can be adjusted to reduce NH<sub>3</sub> and GHG emissions from animal mortality compositing.</p>
