Abstract:

Carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) gasses are released into the atmosphere as a result of livestock activities, and these released gasses have an adverse impact on global climate change. Livestock production has become an important industry and has significantly increased greenhouse gasses emission levels. In this context, livestock production may have a significant role in lowering greenhouse gas emissions with proper strategies. There are some formations that increase greenhouse gas in livestock production systems. Accordingly, these formations are land use, enteric fermentation, fertilizer management, processing, and transport. In these formations, enteric fermentation, depending on the feed intake level of ruminants, and the digestibility of feed by ruminants, methane (CH4) are released in the digestive systems and creates methane (CH4) emissions. Because of their increased biomass and digestive outputs compared to other livestock, ruminants have a major impact on greenhouse gas emissions.  This review proposes recent highlights on how to mitigate greenhouse gas emissions with different reduction strategies from the literature.
