This book presents extensive and updated information about the current developments towards the abatement of methane and other greenhouse gases originated from livestock. Greenhouse gases such as methane and nitrous oxide contributed by livestock are of worldwide concern as these are responsible for global warming as well as animal productivity. Significant efforts have been made by the researcher in different parts of the world to understand the process and mechanisms of global warming with specific emphasis on methanogenesis. We have compiled the information on enteric methane and nitrous oxide production from dairy animals, its impact on global warming and strategies to mitigate these GHGs in a simple, illustrative, and coherent manner, so that students, scientists, academicians and others involved in animal nutrition and animal production science at national or international level will be benefitted. The book covers all aspects of role of ruminants in global warming, rumen microbial diversity, methanogenesis pathway and various biological and non-biological approaches to mitigate anthropogenic methane release. In the end book also covers a variety of techniques for measuring rumen fermentation parameters, culturing and maintenance of anaerobic rumen bacteria and fungi, methanogens, and latest molecular approaches to investigate the rumen microbial diversity and quantification of methanogens are also included. Editors believe that the book will be of immense help to the investigators involved in the field of animal nutrition.
