Book Description
Two experiments were conducted to examine factors that affect nutrient digestion and microbial protein synthesis in cattle. In the first study, four cannulated (rumen, proximal duodenum, terminal ileum) steers were used in a 4 $times$ 4 Latin square design experiment. Steers were fed corn/corn silage (low forage) or alfalfa hay/corn silage (high forage) diets twice or 12 times daily. Site of OM digestion shifted from the rumen to the small intestine and total tract OM digestion was increased when steers were fed the low forage diet. Nonbacterial N flows at the duodenum increased when steers were fed the low forage diet and when fed 12 times daily. Results of this study suggest that energy level of the diet can impact on site of nutrient digestion and supply of nutrients at different sites within the digestive tract. However, feeding frequency had minimal impact on digestive kinetics. In a concurrent project, effects of main treatment factors and bacterial harvesting techniques on bacterial composition were investigated. Whole ruminal contents were collected from steers and fluid- and particle-associated bacteria were obtained. Energy level, feeding frequency and pre-harvesting freezing had only minor effects on composition of harvested bacteria but differences were observed in fluid vs particle-associated or mixed populations of ruminal bacteria. In the second study, four multiple-cannulated steers were used in a 4 $times$ 4 Latin square design to examine effects of forage:concentrate ratio and ruminally degradable protein supply on microbial N Kinetics and net protein synthesis. Steers were fed ammoniated corn cob (high forage) or corn cob/ground corn/cornstarch (low forage) diets supplemented with soybean meal (SBM) or a combination of corn gluten meal and blood meal (CB). Efficiency of bacterial CF synthesis (E$sb{rm MCP}$) decreased when the low forage diet was fed but duodenal bacterial N flows were unaffected by energy level. Feeding SBM vs CB increased E$sb{rm MCP}$ and flow of bacterial N to the small intestine. It was concluded that inclusion of a ruminally degradable protein in the diet may synchronize release of nutrients from proteolysis with release of energy from fermentation.

Book Description
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.

Book Description
Ruminants were domesticated in the Middle East about 10,000 years ago and have since become an inseparable part of human diet, society, and culture. Ruminants can transform inedible plant fiber and non-protein nitrogen into meat, milk, wool and traction, thus allowing human utilization of non-tillable land and industrial by-products. The nutritional flexibility of ruminants is conferred by the rumen´s complex microbial community. Driven by rising income and population growth in emergent economies, the global demand for livestock products, including milk and meat from ruminants, has been increasingly growing, and is predicted to continue growing in the next few decades. The increase in production necessary to satisfy this rising demand is putting much pressure on already dwindling natural resources. There are also concerns about the emissions of methane and nitrous oxide, potent greenhouse gases associated to ruminant production. The need to make ruminant production more efficient in the use of natural resources poses a big challenge to ruminant science, and within it, rumen microbiology. Recent years have seen important advances in basic and applied rumen microbiology and biochemistry. The knowledge generated has significant implications for the efficiency and sustainability of ruminant production and the quality of ruminant products for human health. The present compilation is an update of recent advances in rumen microbiology and ruminant digestion and fermentation, including original research, reviews, and hypothesis and theory articles. We hope that the experimental results, discussion, models and ideas presented herein are useful to foster future research contributing to sustainable ruminant production.

Book Description
This book is intended to be a companion volume to 'Protein Nutrition in Ruminants' (1982, Academic Press), which emphasized both the role of proteins and new systems for their evaluation. Here the focus is on energy-yielding nutrients and problems involved in evaluating them. Nonetheless in both volumes there is explicit recognition of the interdependence of energy and protein nutrition. I have not attempted to review comprehensively all the literature relating to ruminant energy nutrition and must apologize to colleagues whose work is not fully reported. Where possible tables and figures are taken from the studies of our group at the Rowett Research Institute since, if for no other reason, I am most familiar with these data. I have first considered the nutrition of the newborn and have stressed the role of behaviour 'in determining whether nutrients enter or bypass the rumen. The development of the rumen, the of anaerobic fermentation and the roles of various principles . species of rumen bacteria, protozoa and fungi in relation to different substrates, are summarized. This is followed by accounts of the factors affecting the utilization of different substrates and the v vi Preface absorption and metabolism of the end-products of fermentation and digestion, together with estimates of digestive capacity in various segments of the gut. The ruminant's requirements for energy-yielding nutrients is considered in relation to the per formance of various activities and to environmental conditions, particular attention being paid to the requirement for glucose precursors.

Book Description
The Rumen and Its Microbes is a contribution to the ecology of this important microbial habitat. Relatively few microbial habitats have been subjected to a thorough quantitative ecological analysis. The rumen fermentation is peculiarly suitable because of its relatively constant and continuous nature and because of the very rapid rates of conversion of organic matter. Although analysis of the ruminant-microbe symbiosis is still far from complete, knowledge is sufficient for formulation of principles and for identification and measurement of important parameters. The first eight chapters of the book include a description of the rumen and its microbes, their activities, and the extent of these activities. This basic biology provides a framework in which applications to agriculture can be evaluated. These applications are discussed in the last four chapters: host metabolism, variation in the rumen, possible practical applications, and abnormalities in rumen function.

Book Description
Studies in the Agricultural and Food Sciences: Growth in Animals discusses the more advanced concepts of growth, its changes and effects on different animals and systems, and its implications for agriculture. Based on a symposium of the same name, the book defines growth and its effects on the whole body; the biochemical and genetic determinants that affect it; and the effect of thermal environment on growth and its relation with immunity. Growth of bones, muscle nucleic acid and protein, and adipose tissue are also explained. The text also encompasses the relation of growth and gut microflora; the effects of growth-promoting agents in ruminant animals and single-stomach animals; and growth and breeding performance in animals. The growth in mammals and birds for meat production and its effects on the meat quality of animals are also covered in this book. This monograph is recommended for those who would want to start or are currently running animal and poultry farms, as well as for scientists who wish to study the phenomenon of growth for the betterment of agriculture.
