Principles of Protein Nutrition of Ruminants is a cutting-edge examination of the current state of knowledge in this important field. It explores current techniques and concepts, pointing out limitations to these techniques and introducing ideas and criticisms that will be useful in developing new paradigms for research. The scope of the book covers the whole spectrum of investigation from grazing behavior of wild ruminants to cellular and molecular phenomena. Unique aspects of the book include its emphasis on the energy status of the animal as the primary factor in affecting amino acid supply and its discussion of the nature of nitrogenous compounds in feedstuffs.

Farm animals are grown mainly to provide high quality proteins for human use, in the form of meat, milk, eggs, skin and wool. These products are usually formed from lower-quality proteins in complex processes that involve losses through digestion, absorption, and transport. Because proteins are the most expensive major component of the animal diet per unit of weight, the efficiency with which they are used is of great importance biologically and economically. This book begins with a description of the dietary proteins and methods for their measurement. This is followed by detailed accounts of their digestion in ruminants, pigs, poultry and fish. The physiological basis of adsorption of amino acids is discussed in detail. This is followed by reviews of the processes of protein synthesis and degradation and the hormonal and energetic regulation of these processes. Written by a group of experienced scientists, this is the first book in which all of these topics are discussed in detail at a fundamental level. For advanced students and research workers in animal science and agriculture.

This volume is comprised of invited papers presented at the Seventh International Symposium on Ruminant Physiology, held in Sendai, Japan, in September 1989. Papers are invited on the recommendations of 300 international experts. The proceedings of this symposia provides the most comprehensive coverage available of current research in ruminant physiology.

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.

Two questions could not be avoided in the avant-propos of this book; (i) what is the importance to man of ruminant livestock, and (ii) what results of practical relevance in the growing mountain of scientific verbiage could be found in the Proceedings of this Symposium. Herbivores are an integral and critical part of the natural ecosystem which must be preserved because of their impact on human welfare. Wh at makes ruminants especially important to man is that they can thrive on fibrous forage and are thus the only viable enterprise over much of the earth's surface where crop growing is impracti cable. They contribute a wide array of products in addition to 50000 000 tonnes ofmeat (1977) and represent a 'capital reserve' that can be drawn upon in times of emergency: milk for example (450000000 tonnes) can make the difference between subsistence and starvation. About 60% of the world's meat and 80 % of the milk are produced by one third of the world ruminant population in the developed regions and as much as 99 % of the power for agriculture is provided by the ruminant population in developing countries. For the next two decades, a probable increase by 30 % for . cattle and buffalo and more than 40 % for sheep and goats is expected by improving health, fertility, nutrition and genetic potential rather than feed resources.
