Issues such as sustainable animal production and pollution in relation to animal performance, which are being currently debated at international forums, have been thoroughly presented. Regional variations in animal productivity have been highlighted and supported with the latest data in a completely revised chapter. It is expected that the book will provide latest knowledge about various facets of animal production to students and research workers.
