[en] Usually, gestating sows are restrictedly-fed to prevent excessive body weight gain and fat deposition. However, feed restriction causes sustained feeding motivation resulting in stereotypic behaviour and impairment of animal welfare. High fibre diets (HFD) are known to reduce feeding motivation without impairments of performance but the effects of HFD on emissions of pollutant gases are very few studied. Thus, a study was carried out to compare the effect of two fibre contents (standard diet (STD) with 22% of non-starch polysaccharides (NSP) vs. HFD with 44% of NSP) on emissions of ammonia (E-NH3), nitrous oxide (E-N2O), methane (E-CH4) and CO2-equivalents (E-EqCO2) associated to gestating sows. Three successive batches of 10 gestating sows were divided into 2 homogeneous groups and randomly allocated to one of two treatments: STD vs. HFD. The groups were kept separately in two identical rooms equipped with a pen divided into a lying area with slatted floor and five individual feeding stalls with permanent access. Emissions were measured by infrared photoacoustic detection. The HFD significantly decreased ENH3 (12.1 vs. 15.9 g/sow.day) but increased E-EqCO2 (0.68 vs. 0.47 kg/sow.day) in relation with an increase of E-CH4 (18.4 vs. 9.1 g/sow.day), E-N2O being not impacted by the diet, with value around 0.60 g/sow.day. So, the effects of HFD offered to gestating sows on slatted floor on environment seem conflicting with a decrease of NH3 emissions which mainly contribute to acidification of soils and waters and eutrophication, but an increase of CO2-quivalents emissions which contribute to greenhouse effect and climate change.
