ABSTRACT
Livestock are reared throughout the world, and are an important agricultural product in virtually every country. This animal production systems and climate change are inter-related via complex mechanisms. Animal production influences climate change by emitting greenhouse gases such as methane and nitrous oxide. It is estimated to be the livestock sector is contributing a significant share of global GHG emissions, accounting for approximately two-thirds of direct agricultural emissions and about 14.5 percent of total human-induced emissions when supply chains are considered. Therefore, globally, there is an urgent need to reduce the greenhouse gas (GHG) emissions that cause climate change by at least 80 per cent in wealthy countries and to protect the biodiversity which underpins food production. Dietary manipulation, ionophores, bacteriocins, covered anaerobic digesters, awareness creation and intensifying research and development are among the applicable methane mitigation strategies. Moreover, research bodies are also organizing to deliver findings at an international level; which focuses on the identification and development of technologies and practices to increase food production without increasing green house gases emissions.
