Estimation of Microbial Protein Supply in Ruminants Using Urinary Purine Derivatives

This book presents various models, describing the quantitative excretion of purine derivatives in urine, developed for various animal species and breeds, and their use for estimation of microbial protein supply in ruminant livestock. The progress made over the last decade in analytical methods for determining purine derivatives, and a unique approach for estimating microbial protein supply using spot urine samples are also described. This approach of using spot urine samples dispenses with quantitative recovery of urine, enabling its use by field and extension workers for evaluation of the nutritional status of farm animals. The book also highlights future areas of research. The information will help promote the efficient use of conventional and unconventional feed resources for meeting the huge demand for feed being imposed by the a ~Livestock Revolutiona (TM) taking place in developing countries. This book is a good source of reference for research workers, students and extension workers alike.
