Urea as a Protein Supplement presents the significant advances that have been made in ruminant nutrition. This book examines the role of the rumen flora and fauna as synthesizers of protein from non-protein nitrogen sources such as ammonium compounds and urea. Organized into four parts encompassing 23 chapters, this book starts with an overview of the use of urea and other non-protein nitrogen sources in ruminant nutrition. This text then explores the various methods that may be used for the preparation of urea, which involves the dehydration of ammonium carbamate produced by the reaction of carbon dioxide and ammonia at high pressure and temperature. Other chapters consider the ways in which urea could be utilized to increase protein supplies. The final chapter deals with the hydrolysis of urea by urease to ammonia and carbon dioxide, which has been used as a method for determining urea for many years. Agricultural scientists and farmers will find this book useful.
