Genetic aspects of enteric methane emission in ruminants livestock

This review summarizes the importance of methane (CH4) emission in ruminants summarizes the current state of knowledge to genetic aspects on enteric methane , highlighting future research needs directions. Global average temperature has by about 0.7°C in the last century. The Panel on Climate Change (IPCC) reported that anthropogenic greenhouse (GHG), including carbon dioxide (CO2), 4, nitrous oxide (N2O) and halocarbons, have responsible for most of the observed temperature since the middle of the twentieth . Agriculture, particularly livestock, increasingly being recognized as both a contributor the process and a potential victim of . Policy interventions and technical solutions required to address both the impact of livestock on climate change and the of climate change on livestock production. and Agriculture Organization (FAO), that in the next 50 years, the world’s will be called upon to produce more food has been produced in the past 10,000 years, to do so in environmentally sustainable . Therefore, the GHG reduction should be as a public good. The United States congress prospecting to define a price on GHG . Limiting the concentration of CO2 other GHG in Earth’s atmosphere requires a and economic revolution. A costeffective could be the genetic improvement livestock, which produces permanent and changes in perfor mance. Animal in enteric CH4 emission has been in the literature, providing potential for through genetic selection.
