Popis: Livestock is one of the major contributors of greenhouse gases (GHGs). It accounts for 14.5% of the global GHGs emissions like methane (CH4) from enteric fermentation and manure, nitrous oxide (N2O) from manure and fertilizer. Since enteric emissions are a major contributor of CH4 than that of manure emissions hence primary efforts were made on reducing enteric emissions, with minor attention to dung emissions. Many researches were conducted by dietary manipulation to mitigate enteric CH4 emission. However dietary manipulation also had significant effects on manure GHGs emissions too. Several works proved that manure CH4 emissions were increased with high level of concentrate supplementation despite reduction in enteric CH4. Fat and CP content of the diet has shown inconsistent results on manure CH4 emissions. Amount of concentrate in the diet has shown little effect whereas dietary CP content exhibited conflicting effects on manure N2O emissions.
