Feed Additives and Supplements for Ruminants

This book comprehensively reviews various feed additives and supplements that are employed for ruminant production and health. It discusses important strategies of using additives and supplements through rumen fermentation, immunomodulation, nutrient utilization, and cellular metabolism that lead to enhanced milk production, body weight gain, feed efficiency, and reproduction. The book also presents the importance of nutritional supplements such as B-vitamins, advances in mineral nutrition, role of lesser-known trace elements, protected amino acids, slow-release nitrogen and rumen buffers on performance and health of ruminants. In addition, the book explores strategies for improving environmental stewardship of ruminant production by minimizing carbon footprint associated with greenhouse gas emissions, enhancing ruminant-derived food safety through mycotoxin binders, exogenous enzymes, probiotics, flavours, biochar, ionophores, seaweeds and natural phytogenic feed additives with an emphasis on plant secondary metabolites (tannins, saponins and essential oils, etc.). It also details information on silage additives, additives and supplements employed in successful calf rearing, transition cow management as well as to ameliorate the adversity of heat stress in ruminants. Overall, the book is valuable for veterinary and animal science researchers, animal producers, nutrition specialists, veterinarians, and livestock advisors.Table of Content1.Dietary Applications of Exogenous Enzymes to Improve Nutrient Utilization and Performance in Ruminants.- 2.Scope of Microbial Feed Additives in Ruminant Nutrition.- 3.Nano-Mineral Technology in Ruminant Feeding: Progress and Prospects.- 4.Organic Trace Minerals in Ruminant Nutrition: Production, Reproduction, Health, Economics and Environmental Implications.- 5.Newer Trace Elements for Ruminants.- 6.Advancements in Methane Mitigating Feed Additives in Ruminants.- 7.Rumen-Protected Amino Acids for Ruminants.- 8.Phytochemicals as Natural Feed Additives for Ruminants.- 9.Herbal Feed Additives and Supplements for a Sustainable Ruminant Production.- 10.Exploring Condensed Tannin to Control Gastro-Intestinal Parasitism in Small Ruminants.- 11.Mycotoxin Binders for a Safe Ruminant-Derived Food Production.- 12.Role of Flavoured Additives in Ruminant Production.- 13.Potential of Slow-Release Nitrogen in Ruminant Feeding.- 14.Feed Additives for Calves: A Brief Insight on their Classification and Applications.- 15.Additives and Nutritional Supplements for Transition Cows.- 16.Heat Stress in Ruminants and its Mitigation through Nutritional Additives.- 17.Recent Developments in B-Vitamin Nutrition of Dairy Cattle.- 18.Biochar as a Novel Feed Additive for Ruminants.- 19.Prospects of Rare-Earth Elements in Ruminant Production.- 2 0.Silage Additives.- 21.Scope of Seaweeds to Boost Ruminant Productivity.- 22.-Ionophoric Additives to Augment Performance Outcomes and Economics in Ruminants .- 23.Rumen Buffers to Harness Nutrition, Health and Productivity of Ruminants Biographical NoteDr. M.S. Mahesh, is an Assistant Professor (Livestock Farm Complex) at the Faculty of Veterinary and Animal Sciences of Banaras Hindu University, Mirzapur, India. He has graduated in Veterinary Science and Animal Husbandry from Veterinary College, Bengaluru and earned master’s and Ph.D. in Animal Nutrition from ICAR–National Dairy Research Institute, Karnal, India. He was awarded with university gold medals for academic excellence during under-graduation, and afterwards with Junior- and Senior Research fellowships. His areas of specialization include use of novel feed ingredients in ruminants, feed characterization, on-farm diet formulation and optimization, designing species-specific micronutrient premixes, troubleshooting nutritional issues and rationalizing feed additive applications for an augmented performance of dairy cattle and buffaloes. His previous association with animal feed industry helped him gain a broad-spectrum of hands-on experience on the diverse facets ofpractical dairy nutrition. He has published over 25 research/review papers in journals of national and international repute with a few other technical articles. He served as the former member of editorial board of Indian Journal of Animal Nutrition and currently associated as reviewer for many international journals on animal science and multidisciplinary areas. He is a life member of professional societies such as Animal Nutrition Society of India, Animal Nutrition Association and Karnataka Veterinary Council. In his present role, he teaches students and researchers on topics related to animal nutrition.
