“…It can therefore be deduced that the releases from manure contribute to about 20% and 33% of total emissions for R15 and R2.5, respectively, and may explain the difference observed between the two treatments. In manure, the CH 4 -production is promoted by lack of oxygen, high temperature, high level of degradable organic matter, high moisture content, low redox potential, neutral pH and C/N ratio between 15 and 30 (Dong et al, 2007;Costa and Guarino, 2009;Philippe et al, 2011b). The lower emission observed with the solid floor of which 15% was reserved for drainage although significant is however relatively negligible, that is 0.05 g/day per sow.…”

According to EU legislation, group-housed gestating sows must have a minimum of 2.25 m 2 floor area per sow with at least 1.3 m 2 of continuous solid floor of which a maximum of 15% is reserved for drainage openings. The aim of the experiment was to quantify the impact of different drainage openings on ammonia and greenhouse gas emissions. Three successive batches of 10 gestating sows were used. Each batch was divided into two groups kept separately in two identical rooms with similar volume and surface. The solid part of the floor presented 15% drainage openings in the first room and 2.5% in the second room.

“…In literature, large variations were observed between authors with values ranging from 5 to 60 g CH 4 /day per sow (Groot Koerkamp and Uenk, 1997;Godbout et al, 2003;Dong et al, 2007). Methane originates from anaerobic degradation of organic matter in the digestive tract of animal and in the manure.…”

In the European Union, the group-housed pregnant sows have to have a minimal legal available area of 2.25 m2/sow. However, it has been observed that an increased space allowance reduces agonistic behaviour and consecutive wounds and thus induces better welfare conditions. But, what about the environmental impacts of this greater available area? Therefore, the aim of this study was to quantify pollutant gases emissions (nitrous oxide, N2O, methane, CH4, carbon dioxide, CO2and ammonia, NH3), according to the space allowance in the raising of gestating sows group-housed on a straw-based deep litter. Four successive batches of 10 gestating sows were each divided into two homogeneous groups and randomly allocated to a treatment: 2.5v. 3.0 m2/sow. The groups were separately kept in two identical rooms. A restricted conventional cereals based diet was provided once a day in individual feeding stalls available only during the feeding time. Rooms were automatically ventilated. The gas emissions were measured by infra red photoacoustic detection during six consecutive days at the 6th, 9th and 12th weeks of gestation. Sows performance (body weight gain, backfat thickness, number and weight of piglets) was not significantly different according to the space allowance. In the room with 3.0 m2/sow and compared with the room with 2.5 m2/sow, gaseous emissions were significantly greater for NH3(6.29v. 5.37 g NH3-N/day per sow;P< 0.01) and significantly lower for N2O (1.78v. 2.48 g N2O-N/day per sow;P< 0.01), CH4(10.15v. 15.21 g/day per sow;P< 0.001), CO2equivalents (1.11v. 1.55 kg/day per sow;P< 0.001), CO2(2.12v. 2.41 kg/day per sow;P< 0.001) and H2O (3.10v. 3.68 kg/day per sow;P< 0.001). In conclusion, an increase of the available area for group-housed gestating sow kept on straw-based deep litter seems to be ambiguous on an environmental impacts point of view. Compared with a conventional and legal available area, it favoured NH3emissions, probably due to an increased emitting surface. However, about greenhouse gases, it decreased N2O, CH4and CO2emissions, probably due to reduced anaerobic conditions required for their synthesis, and led to a reduction of CO2equivalents emissions.
