Protein Contribution of Feedstuffs for Ruminants: Application to Feed Formulation covers papers about the findings and knowledge on the ""Evaluation of the Protein Contribution of Feedstuffs for Ruminant"". The book presents papers about the recent advances in the knowledge of protein evaluation for ruminants; similarities and differences between rumen fermentation and postruminal utilization; and methods of assessing proteins for ruminants. The text also covers papers about protected proteins and amino acids for ruminants; validation and application of principles of protein evaluation for ruminants; practical feeding trials in Norway; and protein-energy interrelationships for growing and for lactating cattle. A report of co-ordinated trials carried out on commercial farms in the UK is also presented in the book. The text will be invaluable to feed compounders, research workers, advisors, farmers and agricultural students.
This book brings together the latest research on protein absorption by ruminants and takes a look at the calculation of optimum nutrient requirements, including bacterial digestion, in the calculations. It also describes the parameters of nitrogen conversion in the ruminant and examines the different kinds of protein found in animal feedstuffs. ;ITAnimal Feed Science and Technology;IT calls it "essential for all scientists and teachers actively working in ruminant nutrition research and instruction."
Impacts on Nutrition, Physiology and Reproduction of Livestock

Naturally occurring salt tolerant and halophytic plants (trees, shrubs, grasses, and forbs) have always been utilized by livestock as a supplement or drought reserve. Salt tolerant forage and fodder crops are now being planted over wide areas. Increasingly, large-scale production of fodder on formerly abandoned irrigated cropland has allowed salt tolerant and halophytic feedstuffs to be mainstreamed into the supply chain for feedlots. Feeding salty feeds to livestock has been evaluated in many countries with good outcomes especially as a way to improve livestock nutrition and productivity. Better ways have been devised to use these potentially valuable feed resources. These feedstuffs are best fed in mixed rations. Substituting conventional fodder with up to 30 percent of the diets comprising halophytic feedstuffs have proved most successful for ruminant livestock but special formulations have been devised for poultry and rabbits. There are big savings on the import of costly feedstuffs and benefits to livelihoods of those dependent on scattered, sparse and unreliable forage/fodder in the world’s drylands that cover about 40 percent of the world’s land surface. This book is written by leading authorities from many different countries. It reviews past and current work on the animal-oriented aspects of the utilization of feedstuffs derived from salt tolerant and halophytic plants. It brings to the reader (scientist, researcher, academics and their students, policy makers, and livestock operators) an up-to-date analysis of the important issues related to salt-rich feedstuffs (nutrition, productivity, and reproduction).
This monumental text-reference places in clear persepctive the importance of nutritional assessments to the ecology and biology of ruminants and other nonruminant herbivorous mammals. Now extensively revised and significantly expanded, it reflects the changes and growth in ruminant nutrition and related ecology since 1982. Among the subjects Peter J. Van Soest covers are nutritional constraints, mineral nutrition, rumen fermentation, microbial ecology, utilization of fibrous carbohydrates, application of ruminant precepts to fermentive digestion in nonruminants, as well as taxonomy, evolution, nonruminant competitors, gastrointestinal anatomies, feeding behavior, and problems fo animal size. He also discusses methods of evaluation, nutritive value, physical struture and chemical composition of feeds, forages, and broses, the effects of lignification, and ecology of plant self-protection, in addition to metabolism of energy, protein, lipids, control of feed intake, mathematical models of animal function, digestive flow, and net energy. Van Soest has introduced a number of changes in this edition, including new illustrations and tables. He places nutritional studies in historical context to show not only the effectiveness of nutritional approaches but also why nutrition is of fundamental importance to issues of world conservation. He has extended precepts of ruminant nutritional ecology to such distant adaptations as the giant panda and streamlined conceptual issues in a clearer logical progression, with emphasis on mechanistic causal interrelationships. Peter J. Van Soest is Professor of Animal Nutrition in the Department of Animal Science and the Division of Nutritional Sciences at the New York State College of Agriculture and Life Sciences, Cornell University.
Obviously not a book for vegetarians, though as Ensminger (Agriservices Foundation; Clovis, CA) and Perry (CA State U., Fresno) remind us: "All flesh is grass!" Since the 1987 edition, the beef industry's challenges have further calved despite additional cattle breeds: namely, The War on Fat, 1990, and several beef quality audits (prior to recent mad cow disease and E. coli scares--the former, but not the latter, is covered). Topics span: the history and business of cattle raising; nutrient requirements, health, behavior, genetics, and slaughter; weights and measures of animals and feeds; breed registry associations/periodicals; and US and Canadian colleges of agriculture.

The seventh edition of this classic text offers expanded material on traditional Dairy Herd Improvement (DHI) records, a new chapter on the computer as a dairy management tool, increased coverage of financial management, and thoroughly revised chapters on dairy nutrition that include the latest concepts in protein nutrition, forage evaluation, and feeding management. Like previous editions, the text focuses on showing how to use current tools and practices of successful dairy herd managers to produce and market milk and cattle more profitably.
Mosby's Comprehensive Review for Veterinary Technicians, 3rd edition introduces and reviews the material in each of your veterinary technology courses. Key topics ranging from basic and clinical science, diagnostics and applications, to professional practices and issues are presented in a user-friendly outline format that is ideal whether you're a new student or you're reviewing for your certification exams. This title includes additional digital media when purchased in print format. For this digital book edition, media content is not included. Comprehensive coverage of veterinary technology spans basic and clinical sciences, applications, patient management, nursing, nutrition, anesthesia and pharmacology, as well as personal, practice and professional management skills - everything you need for both the U.S. and Canadian certification exams. Care of large animals, birds, reptiles and laboratory animals, in addition to cats and dogs, is included. Chapter outlines, learning outcomes and expanded glossaries help you comprehend and retain essential material. Summary tables are ideal for reference or review. Review questions at the end of each chapter, in addition to a 300-question comprehensive review exam, test and reinforce your knowledge of veterinary technology. Six appendixes ensure crucial resources are always at your fingertips. State-of-the-art Alternative Imaging Technology chapter discusses computed tomography and nuclear scintigraphy to complement ultrasound technology.
