Book Description
Environmental stress is one of the most significant factors affecting livestock performance and health, and it is only expected to increase with effects of global warming. Environmental Physiology of Livestock brings together the latest research on environmental physiology, summarizing progress in the field and providing directions for future research. Recent developments in estimating heat stress loads are discussed, as well as key studies in metabolism, reproduction, and genetic expressions. Environmental Physiology of Livestock begins with a survey of current heat indexing tools, highlighting recent discoveries in animal physiology, changes in productivity levels, and new technologies available to better estimate stress response. Using this synopsis as a point of orientation, later chapters hone in on major effects of heat stress, including changing metabolic pathways and nutrient requirements, endocrine regulation of acclimation to environmental stress, and reduced reproductive performance. The text concludes with a thorough discussion of environmental effects on gene expressions, providing important insight for future breeding practices. Environmental Physiology of Livestock is a globally contributed volume and a key resource for animal science researchers, geneticists, and breeders.

Book Description
Given the importance of livestock to the global economy, there is a substantial need for world-class reference material on the sustainable management of livestock in diverse eco-regions. With uncertain climates involving unpredictable extreme events (e.g., heat, drought, infectious disease), environmental stresses are becoming the most crucial factors affecting livestock productivity. By systematically and comprehensively addressing all aspects of environmental stresses and livestock productivity, this volume is a useful tool for understanding the various intricacies of stress physiology. With information and case studies collected and analyzed by professionals working in diversified ecological zones, this book explores the influence of the environment on livestock production across global biomes. The challenges the livestock industry faces in maintaining the delicate balance between animal welfare and production are also highlighted.

Book Description
Dr. Anjali Aggarwal is working as a Senior Scientist at National Dairy Research Institute, Karnal (India). She holds a PhD degree in Animal Physiology and is involved in research and teaching at post-graduate level. Her area of research work is stress and environmental physiology. She has more than 50 publications, two technical bulletins, four manuals and many book chapters to her credit. She has successfully guided many post-graduate and PhD students. Her major research accomplishments are on microclimatic modification for alleviation of heat and cold stress, mist and fan cooling systems for cows and buffaloes, and use of wallowing tank in buffaloes. Her work involves the use of technology of supplementing micronutrients during dry period and early lactation to crossbred and indigenous cows for alleviating metabolic and oxidative stress and improved health and productivity. Studies are also done in her lab on partitioning of heat loss from skin and pulmonary system of cattle and buffaloes as a result of exercise or exposure to heat stress. Dr. R.C. Upadhyay is working as Head, Dairy Cattle Physiology Division at National Dairy Research Institute, Karnal (India). He graduated in Veterinary Sciences and obtained his PhD degree in Animal Physiology. His area of recent research is climate change, stress, and environmental physiology. His major research accomplishment is on climate change impact assessment of milk production and growth in livestock. His work also involves studying methane conversion and emission factors for Indian livestock and use of IPCC methodology of methane inventory of Indian livestock. Heat shock protein-70 expression studies in cattle and buffaloes are also done in his lab. Draught animal power evaluation, fatigue assessment, work-rest cycle and work limiting factors form the highlights of his work. Studies on partitioning of heat loss from skin and pulmonary system of cattle and buffaloes and electrocardiographic studies in cattle, buffalo, sheep and goat are also undertaken in his lab. He has more than 75 research papers, four books and several book chapters to his credit. Technologies developed and research done by him include methodology of methane measurement: open and closed circuit for cattle and buffaloes; inventory of methane emission from livestock using IPCC methodology; livestock stress index: thermal stress measurement based on physiological functions; and draught power evaluation system and large animal treadmill system. He received training in Radio-nuclides in medicine at Australian School of Nuclear Technology, Lucas heights, NSW, Australia in 1985 and Use of radioisotopes in cardiovascular investigations at CSIRO, Prospect, NSW, Australia, during 1985-86. He has guided several post-graduate and PhD students. He is recipient of Hari Om Ashram Award-1990 (ICAR) for outstanding research in animal sciences.

Book Description
Michael Akers provides the basics for understanding mammary development and lactation and conveys the critical regulatory events in lactation. This text willl prove to be an invaluable overview of mamorary development and lactation for undergraduates and graduates studying lactation, new researchers, and as a review for established scientists. Additionally, the book will be an important resource for professionals in the animal and dairy industry and for those in other scientific disciplines such as food chemistry, cell biology, and endocrinology whose work is closely tied to mammary gland development and function. Lactation and the Mammary Gland covers growth and development of the mammary gland including comparisons between species. It imparts and emphasizes the critical nature of mammary growth and the onset of lactation at the time of parturition. Special emphasis is given to the endocrine and growth factor regulation of both mammogenesis and lactogenesis. A thorough discussion of the role of growth hormone in development and maintenance of lactation or galactopoiesis adds to this book's value as a text and reference. The author reviews the presence of hormones, growth factors, and other bioactive compounds in milk and mammary secretions as well as the potential for use of the mammary gland as a bioreactor in the pharmaceutical industry. A description of the nutritional and management factors in milk production round out the book's comprehensive coverage.

Book Description
This book presents a timely collection of reviews by experts in periconception and fertilization. The book provides a good introduction for those new to the field as well as those who have worked in this field for some time, but not have been able to keep up-to-date with recent advances on the topic. The book reviews the current knowledge in this field, then focuses its attention on short-term and long-term effects of the periconception period, both from a physiological and medical perspective. Finally the volume covers the examination of the potential mechanisms involved in controlling periconception period. From the early days of discovery about the basics of the fertilization process, scientists have known that early events happening during conception play a major part in the creation of new offspring. However, until nearly a decade ago we thought these events were just concerned with the conception and nothing to do with lifelong health and welfare, or wellbeing of the offspring. Early indications from IVF in sheep and cattle suggested that the embryo culture conditions employed in the laboratory could result in unusually large and unhealthy offspring. These observations sounded alarm bells and stimulated research into the impacts of in vivo and in vitro conditions on the health of embryos and offspring. This book provides a summary of the state-of-the-art research being done to more fully understand the importance of the periconception environment.
