“…However, country-specific values are recommended to improve estimates. Recent investigations of CH 4 emissions from pig and cattle slurry storage in Mid Sweden (average annual temperature 88C) showed MCF to be considerably lower, only 3% (Rodhe et al, 2012), which implies a substantially lower manure storage emissions estimate than the IPCC suggested default value Cederberg, Henriksson and Berglund of 10% yields. Anaerobic digestion is considered to be one of the most promising mitigation techniques in agriculture, therefore it is important to have reasonably accurate parameter data for calculating GHG emissions from manure storage.…”

The last decade has seen an increase in environmental systems analysis of livestock production, resulting in a significant number of studies with a holistic approach often based on life-cycle assessment (LCA) methodology. The growing public interest in global warming has added to this development; guidelines for carbon footprint (CF) accounting have been developed, including for greenhouse gas (GHG) accounting of animal products. Here we give an overview of methods for estimating GHG emissions, with emphasis on nitrous oxide, methane and carbon from land use change, presently used in LCA/CF studies of animal products. We discuss where methods and data availability for GHGs and nitrogen (N) compounds most urgently need to be improved in order to produce more accurate environmental assessments of livestock production. We conclude that the top priority is to improve models for N fluxes and emissions from soils and to implement soil carbon change models in LCA/CF studies of animal products. We also point at the need for more farm data and studies measuring emissions from soils, manure and livestock in developing countries.

“…Berg et al (2006) reported relatively high emission from slurry covered with straw, perlite or Leca â compared to uncovered slurry. The magnitude of such seasonal variations are dependent on many factors including manure characteristics, environmental conditions, and management practices (Clemens et al, 2006;Rodhe et al, 2012;Petersen et al, 2013). The magnitude of such seasonal variations are dependent on many factors including manure characteristics, environmental conditions, and management practices (Clemens et al, 2006;Rodhe et al, 2012;Petersen et al, 2013).…”

Livestock manure contributes considerably to global emissions of ammonia (NH3 ) and greenhouse gases (GHG), especially methane (CH4 ) and nitrous oxide (N2 O). Various measures have been developed to mitigate these emissions, but most of these focus on one specific gas and/or emission source. Here, we present a meta-analysis and integrated assessment of the effects of mitigation measures on NH3 , CH4 and (direct and indirect) N2 O emissions from the whole manure management chain. We analysed the effects of mitigation technologies on NH3 , CH4 and N2 O emissions from individual sources statistically using results of 126 published studies. Whole-chain effects on NH3 and GHG emissions were assessed through scenario analysis. Significant NH3 reduction efficiencies were observed for (i) housing via lowering the dietary crude protein (CP) content (24-65%, compared to the reference situation), for (ii) external slurry storages via acidification (83%) and covers of straw (78%) or artificial films (98%), for (iii) solid manure storages via compaction and covering (61%, compared to composting), and for (iv) manure application through band spreading (55%, compared to surface application), incorporation (70%) and injection (80%). Acidification decreased CH4 emissions from stored slurry by 87%. Significant increases in N2 O emissions were found for straw-covered slurry storages (by two orders of magnitude) and manure injection (by 26-199%). These side-effects of straw covers and slurry injection on N2 O emission were relatively small when considering the total GHG emissions from the manure chain. Lowering the CP content of feed and acidifying slurry are strategies that consistently reduce NH3 and GHG emissions in the whole chain. Other strategies may reduce emissions of a specific gas or emissions source, by which there is a risk of unwanted trade-offs in the manure management chain. Proper farm-scale combinations of mitigation measures are important to minimize impacts of livestock production on global emissions of NH3 and GHG.

“…According to the guidelines for National Greenhouse Gas Inventories (IPCC, 2006) Chae et al, 2008;Vedrenne et al, 2008;Jarret et al, 2011;Dämmgen et al, 2012b Jarret et al, 2011;Dämmgen et al, 2012b;Rodhe et al, 2012). In their study, Moller et al (2004) showed that during long-term storage (90 days), the slurry MCF value increased from 5.3 to 31.3% at temperatures ranging from 15 to 20 C, respectively.…”

A B S T R A C TThe environmental impacts of livestock production are attracting increasing attention, especially the emission of greenhouse gases (GHGs). Currently, pork is the most widely consumed meat product in the world, and its production is expected to grow in the next few decades. This paper deals with the production of carbon dioxide (CO 2 ), methane (CH 4 ) and nitrous oxide (N 2 O) by animals and by manure from pig buildings, with a focus on the influence of rearing techniques and nutrition. GHG emissions in piggeries originate from animals through CO 2 exhalation and CH 4 enteric fermentation, and from manure through the release of CO 2 , CH 4 and N 2 O. The level of the CO 2 exhalation (E-CO 2, pig ) depends on the physiological stage, the body weight (BW), the production level and the feed intake of the animals concerned. Enteric CH 4 (E-CH 4, pig ) is principally related to dietary fibre intake and the fermentative capacity of the pig's hindgut. Based on a review of the literature, the following equations are proposed in order to estimate E-CO 2, pig (in kg day À1) and E-CH 4,pig (in g day À1 ) for fattening pigs: E-CO 2,; E-CH 4,pig = 0.012 Â dRes; with BW (in kg) and dRes for digestible residues (in g day À1 ). Numerous pathways are responsible for GHG production in manure. In addition, the microbial, physical and chemical properties of manure interact and modulate the level of emissions. Influencing factors for removal systems for both liquid and solid fractions of manure have been investigated. A large range of parameters showing an impact on the level of GHG production from pig houses has been reported. However, few of these can be considered unquestionably as GHG mitigation techniques because some strategies have shown contradictory effects depending on the gas, the circumstances and the study. Nevertheless, frequent manure removal seems to be an efficient means to reduce concurrently CO 2 -, CH 4 -and N 2 O-emissions from pig buildings for both slatted and bedded floor systems. Manure removal operations may be associated with specific storage conditions and efficient treatment in order to further reduce emissions. Several feeding strategies have been tested to decrease GHG emissions but they seem to be ineffective in reducing emissions both significantly and durably. In general, good management practices that enhance zootechnical performance will have beneficial consequences on GHG emission intensity. Taking into account the results described in the literature regarding CO 2 -, CH 4 -and N 2 Oproduction from animals and manure in pig houses, we estimate total GHG emissions to 448.3 kg CO 2 equiv. per slaughter pig produced or 4.87 kg CO 2 equiv. per kg carcass. The fattening period accounts for more than 70% of total emissions, while the gestation, lactation and weaning periods each contribute to about 10% of total emissions. Emissions of CO 2 , CH 4 and N 2 O contribute to 81, 17 and 2% of total emissions from pig buildings, representing 3.87, 0.83 and 0.11 kg CO 2 equiv. per kg carcass, re...
