Effect of sward management on the emissions of CH4 and N2O from faeces of sheep grazing Italian ryegrass pastures

In conclusion, our study showed that the RN grazing management, based on animal behaviour, resulted in higher daily N excretion per animal and higher CH4 and N2O emissions from faeces of sheep grazing Italian ryegrass pastures. This study contributes to improve GHG national inventories for the subtropical Brazilian climatic conditions, where estimations from CH4 and N2O emissions factors for faeces from growing sheep grazing Italian ryegrass are markedly lower than the values reported by IPCC Default Tier 1.
