Effects of a high-fibre diet on ammonia and greenhouse gas emissions from gestating sows and fattening pigs
Abstract This study aims to measure under barn conditions the emissions of NH3, N2O, CH4 and CO2 associated with gestating sows (trial 1) and fattening pigs (trial 2) fed either a control diet (CTD) based on cereals or a high-fibre diet (HFD) based on sugar beet pulp (SBP). Three successive batches of 10 Belgian Landrace gestating sows were used for trial 1. Two successive batches of 24 Piétrain × Belgian Landrace fattening pigs were used for trial 2. Animals were kept on slatted floor. The gas emissions were measured by infrared photoacoustic detection and expressed per day and per livestock unit, equals to 500 kg body weight. Similar trends were observed for both animal types. With HFD, the NH3 emissions were reduced (27.2 vs. 36.5 g for the gestating sows, P < 0.001; 23.2 vs. 45.0 g for the fattening pigs, P < 0.001) but the CH4 emissions were increased (41.5 vs. 21.0 g for gestating sows, P < 0.001; 37.9 vs. 27.2 g for fattening pigs, P < 0.001). The fibre content of the diet had not significant impact on N2O emissions (around 1.4 g for gestating sows and 2.1 g for fattening pigs, P > 0.05), and on CO2 emissions (around 6.0 kg for gestating sows and 9.1 kg for fattening pigs, P > 0.05). Most of manure parameters did not statistically differ regarding the treatment. Reproductive performance and body condition of the sows were not affected by the diet. However, growth performance and carcass traits of the HFD-fed fattening pigs were deteriorated compared to CTD.
Highlights Dietary fibre has significantly lowered NH3 emissions from fattening pigs and gestating sows. CH4 emissions were increased in the case of dietary fibre. N2O and CO2 emissions were not impacted by the dietary fibre content. Growth performance of fattening pigs was impaired by high level of fibre inclusion.
