The book presents latest comprehensive information on the various aspects of developing strategies in animal nutrition for environment friendly livestock production system. The book has covered the concepts like Animal agriculture and carbon footprints; Strategies to mitigate enteric methane production; Methane production potential of different feedstuffs, so as to formulate the rations with low enteric methane production; Nutritional interventions like manipulating rumen microbial ecosystem; Strategic supplementation of nutraceuticals; Improving the bioavailability of nutrients at cellular level by using nanotechnology; Forage production throughout the year and production of hydroponics green fodders. The impact of pesticide residues and toxicants in feedstuffs on the productive and reproductive performance has been covered exhaustively. Biomarkers for assessing the nutritional status of dairy animals and alternate evaluation techniques are also discussed in details. The book covers the development of functional/designer animal products by manipulating the feeding practices to prove the saying of Hippocrate "Let food be thy medicine and medicine be thy food". This book will be useful and highly informative for PG students and faculty, researchers/scientists and others working in a particular specialized field in Animal Nutrition.
