The Rumen Protozoa

All ruminants are dependent on the microorganisms that live in their forestomach - the rumen - to break down ingested feed constituents into a form that the host animal can utilize. Protozoa are part of this complex ruminal population and are essential for the nutritional well-being and productivity of the host ruminant. Over 30 different genera (nearly 300 species) of protozoa from the rumen ecosystem have been described since their initial discovery nearly 150 years ago. This book brings together the available information on these protozoa. It describes their characteristic anatomical features and includes detailed sections on techniques and methodologies for the isolation and cultivation of these fastidious, oxygen-sensitive microorganisms. Their occurrence, biochemistry, physiology and role in the ruminal ecosystem are comprehensively reviewed. The book includes a discussion of potential improvements in the nutrition and productivity of the host ruminant by means of the manipulation of the protozoal population and its activities. This monograph on physiology, microbial ecology and veterinary medicine is intended for researchers, veterinarians, and breeders.
