It is a commonly held belief that athletes, particularly body builders, have greater requirements for dietary protein than sedentary individuals. However, the evidence in support of this contention is controversial. This book is the latest in a series of publications designed to inform both civilian and military scientists and personnel about issues related to nutrition and military service. Among the many other stressors they experience, soldiers face unique nutritional demands during combat. Of particular concern is the role that dietary protein might play in controlling muscle mass and strength, response to injury and infection, and cognitive performance. The first part of the book contains the committee's summary of the workshop, responses to the Army's questions, conclusions, and recommendations. The remainder of the book contains papers contributed by speakers at the workshop on such topics as, the effects of aging and hormones on regulation of muscle mass and function, alterations in protein metabolism due to the stress of injury or infection, the role of individual amino acids, the components of proteins, as neurotransmitters, hormones, and modulators of various physiological processes, and the efficacy and safety considerations associated with dietary supplements aimed at enhancing performance.

Variations in feeding frequency may lead to difference in utilization of dietary nutrients. The effects of feeding frequency have been tested in growing pigs and finishing pigs using respiratory quotient and postprandial kinetics of plasma metabolites. A reduced feeding frequency resulted in an increased lipogenesis and proteolysis shortly after the meal both in growing and finishing pigs. Nevertheless, growing and finishing pigs exhibit different metabolic pathways when feeding frequency is reduced.

As world population increases, demand for food and particularly animal products is expected to grow substantially. Because of limited area for expansion of animal agriculture and growing consumer concern for the environmental impact of animal production, gains in animal efficiency will have to be part of the solution. This book addresses key issues of how energy and protein are utilized and interact in farm animals from the molecular to the whole animal and even to the herd or group level of organization. It contains state-of-the-art research and reviews on several topics of nutrient utilization and metabolism from top scientists worldwide. Key issues addressed include energy/protein interactions, methodology such as in vitro and in vivo techniques, regulation including pre-natal programming and endocrine regulation, modeling and systems biology (including a tribute to the late Professor R. Lee Baldwin of the University of California, Davis, a leader in the field), products and health of animals, tissue metabolism, and environmental sustainability in agriculture. This book is a valuable resource for researchers, students, policy makers, producers and industry professionals believing that a better understanding of metabolism and nutrition of farm animals is part of the solution.

Abstract: Since protein is so important in the study of nutrition, a symposium was held to examine aspects of protein metabolism in animals, including protein biosynthesis, absorption and turnover. Rates of synthesis and degradation of proteins, as well as the absorption of amino acids from the gastrointestinal tract of ruminants can now be measured. The contents of digested protein and amino acids in feed rations function as indicators for animal protein synthesis; the level of feed intake affects protein production, especially intakes of nitrogen and energy. Digestibilities of amino acids of different feeds containing crude protein are compared. Calculations of nitrogen requirements for cattle have been determined. Protein utilization is influenced by energy losses during urea formation and excretion, and maximal organic digestion depends on ammonia and pH levels. Long term feeding experiments demonstrated the amounts of protein needed for a given production. Production of animal protein in response to human protein demands are discussed.

A succinct review of hundreds of studies on the regulation of protein mass and protein turnover in the human body. The book summarizes the biochemistry of protein synthesis and breakdown, and explains the methods that are used to examine protein metabolism in humans, together with their limitations. Chapters review the effects of nutrition, hormones, metabolic substrates, and physical activity, while various topics of clinical interest include cancer, diabetes, tissue injury, pregnancy, renal disease, muscular dystrophies, and other conditions. Normal values are presented for turnover of proteins in the whole body and individual organs, and for turnover of many individual proteins. This is thus a valuable resource for physiologists, nutritionists, and clinicians interested in the regulation of body protein stores in health and disease. For scientists primarily interested in the basic aspects of protein metabolism, it shows how the basic knowledge is being applied to the study of humans.

Modern Methods in Protein Nutrition and Metabolism grew out of a series of seminars (Modern Views in Nutrition) held in 1989 at Iowa State University. These seminars and this book were financed primarily through the Wise and Helen Burroughs Lectureship endowment generously established by the late Dr. Wise Burroughs and his wife Helen. This book comprises 12 chapters, and begins with a focus on amino acid analysis in food and physiological samples. Succeeding chapters go on to discuss concepts and techniques on nitrogen balance; determination of the amino acid requirements of animals; and novel methods for determining protein and amino acid digestibilities in feedstuffs. Other chapters cover measurement of protein digestion in ruminants; evaluation of protein status in humans; surgical models to measure organ amino acid metabolism in vivo; and measurement of whole-body protein content in vivo. The remaining chapters discuss estimation of protein synthesis and proteolysis in vitro; isotopic estimation of protein synthesis and proteolysis in vivo; n-glycine as a tracer to study protein metabolism in vivo; and mathematical models of protein metabolism. This book will be of interest to practitioners in the fields of human nutrition and medicine.
