Reducing the formation of enteric methane and influencing the methane potential of manure via nutrition of pigs : literature study

“…For all categories of pig or sow manure, higher emissions are observed with a longer duration of indoor manure storage. A system that daily removed the manure out of the barn resulted in a reduction by 90% of methane emission from the house of fattening pigs in the study reported by Booijen et al (2023). Petersen et al (2016) used 11 cattle and 20 pig manure samples collected beneath slatted floors on six Danish farms to estimate in laboratory assay total methane emissions of 0.011 kg and 0.030 kg CH4/kg VS 31 from cattle and pig manure, respectively, assuming a retention time in pits of 15 and 30 d for pig and cattle manure, respectively.…”

“…Public Wageningen Livestock Research Report 1485 | 55 At animal house level, emissions originate from the release by animals (enteric formation) and from the manure stored under the slatted floors of pens. When the experimental design provides for frequent emptying of the manure, concentrations measured in the air in the room correspond almost entirely to enteric formation, as in the studies reported by Seradj et al (2018) and Booijen et al (2023). Fibrous diets with up to 48% NSP provided to fattening pigs or gestating sows housed on slatted floors or bedded floors have been reviewed by and were shown to increase CH4 emission by 13-52%…”
