“…Mechanical or intermittent aeration of manure during storage can also reduce CH 4 emissions (Osada, 2000;Martinez et al, 2003;Loyon et al, 2007), although mechanical aeration may lead to increased CO 2 emissions (Petersen and Sommer, 2011). Decreasing manure temperature to ,108C by removing the manure from the building and storing it outside in cold Gerber, Hristov, Henderson, Makkar, Oh, Lee, Meinen, Montes, Ott, Firkins, Rotz, Dell, Adesogan, Yang, Tricarico, Kebreab, Waghorn, Dijkstra and Oosting climates can also mitigate CH 4 emissions (Monteny et al, 2006).…”

Although livestock production accounts for a sizeable share of global greenhouse gas emissions, numerous technical options have been identified to mitigate these emissions. In this review, a subset of these options, which have proven to be effective, are discussed. These include measures to reduce CH 4 emissions from enteric fermentation by ruminants, the largest single emission source from the global livestock sector, and for reducing CH 4 and N 2 O emissions from manure. A unique feature of this review is the high level of attention given to interactions between mitigation options and productivity. Among the feed supplement options for lowering enteric emissions, dietary lipids, nitrates and ionophores are identified as the most effective. Forage quality, feed processing and precision feeding have the best prospects among the various available feed and feed management measures. With regard to manure, dietary measures that reduce the amount of N excreted (e.g. better matching of dietary protein to animal needs), shift N excretion from urine to faeces (e.g. tannin inclusion at low levels) and reduce the amount of fermentable organic matter excreted are recommended. Among the many 'end-of-pipe' measures available for manure management, approaches that capture and/or process CH 4 emissions during storage (e.g. anaerobic digestion, biofiltration, composting), as well as subsurface injection of manure, are among the most encouraging options flagged in this section of the review. The importance of a multiple gas perspective is critical when assessing mitigation potentials, because most of the options reviewed show strong interactions among sources of greenhouse gas (GHG) emissions. The paper reviews current knowledge on potential pollution swapping, whereby the reduction of one GHG or emission source leads to unintended increases in another.

“…In the model, N losses in N 2 O form are estimated as a fixed percentage (0.2%) of N excreted (in the building), or of N stored (in the slurry tank) (IPCC, 2006). N 2 emission is estimated considering a ratio (N 2 O/N 2 ) equal to 1 : 5 (Loyon et al, 2007).…”

“…Matter and gaseous flows during aerobic treatment of slurry have been modelled by Bé line et al (2004) and Loyon et al (2007), respectively, for the three main treatment schemes found in France. In these schemes, the nitrification and denitrification processes are associated with other slurry manipulations.…”

A model has been developed to predict pig manure evolution (mass, dry and organic matter, N, P, K, Cu and Zn contents) and related gaseous emissions (methane (CH 4 ), nitrous oxide (N 2 O) and ammonia (NH 3 )) from pig excreta up to manure stored before spreading. This model forms part of a more comprehensive model including the prediction of pig excretion. The model simulates contrasted management systems, including different options for housing (slatted floor or deep litter), outside storage of manure and treatment (anaerobic digestion, biological N removal processes, slurry composting (SC) with straw and solid manure composting). Farmer practices and climatic conditions, which have significant effects on gaseous emissions within each option, have also been identified. The quantification of their effects was based on expert judgement from literature and local experiments, relations from mechanistic models or simple emission factors, depending on existing knowledge. The model helps to identify relative advantages and weaknesses for each system. For example, deep-litter with standard management practices is associated with high-greenhouse gas (GHG) production (1125% compared to slatted floor) and SC on straw is associated with high NH 3 emission (115% compared to slatted floor). Another important result from model building and first simulations is that farmer practices and the climate induce an intra-system (for a given infrastructure) variability of NH 3 and GHG emissions nearly as high as inter-system variability. For example, in deep-litter housing systems, NH 3 and N 2 O emissions from animal housing may vary between 6% and 53%, and between 1% and 19% of total N excreted, respectively. Thus, the model could be useful to identify and quantify improvement margins on farms, more precisely or more easily than current methodologies.

“…Such methods are more accurate, but have different requirements for the experimental area of the test. Common ammonia absorption solutions are boric acid [9], orthophosphoric acid [10], sulfuric acid [11][12] and oxalic acid [13]. Indoor analysis methods include titration, conductivity method, colorimety method [14].…”
