Livestock, especially ruminants such as cattle, produce methane (CH 4) as part of their normal digestive processes. This process is called enteric fermentation, and it represents over a quarter of the emissions from the Agriculture economic sector. The way in which manure from livestock is managed also contributes to CH 4 and N 2 O emissions. Different manure treatment and storage methods affect how much of these greenhouse gases are produced.
oxide (N2O) emissions from livestock manure management systems. Cattle are an important source of CH4 in many countries because of their large population and high CH4 emission rate due to their ruminant digestive system. Methane emissions from manure management tend to be smaller than enteric emissions, with the most

Different manure treatment and storage methods affect how … Mar 22, 2010 Many studies on methane (CH4) and nitrous oxide (N2O) emissions from livestock industries have revealed that livestock production directly contributes to greenhouse gas (GHG) emissions through enteric fermentation and manure management, which causes negative impacts on … Methane emissions also result from livestock and other agricultural practices and by the decay of organic waste in municipal solid waste landfills. Nitrous oxide (N 2 O): Nitrous oxide is emitted during agricultural and industrial activities, combustion of fossil fuels and solid waste, as well as during treatment of wastewater.

Effect of feeding practices and manure quality on CH4 and N2O emissions from uncovered cattle manure heaps in Kenya. program of the International Livestock Abstract. Ongoing intensification and specialisation of livestock production lead to increasing volumes of manure to be managed, which are a source of the greenhouse gases (GHGs) methane (CH4) and nitrous oxide (N2O).

Ruminant livestock – mainly cattle – for example, produce methane through their digestive processes (in a process known as ‘enteric fermentation’). Opportunities to reduce N2O and CH4 emissions from livestock manure are illustrated in Fig.
Livestock husbandry causes emissions of nitrous oxide (N2O) and methane (CH 4).
