Hardcover. Condizione: Very Good. 2nd Edition. Hardcover, iv + 192 pages, NOT ex-library. Little minor wear, book is clean and bright with unmarked text, free of inscriptions and stamps, firmly bound. Issued without a dust jacket. -- The book is a technical guide to the gastrointestinal tract and its microflora, specifically focusing on animal nutrition and performance. This 2008 second edition was thoroughly revised to incorporate modern understanding of how gut health influences immunity and the overall productivity of livestock. The book serves as an introduction to the identity, location, and activity of gastrointestinal microflora. It explores how these microorganisms benefit the health and performance of animals by interacting with the immune system and protecting against infections. The text is structured to cover the biological foundations of the gut followed by various nutritional interventions: - Biological Foundations: Chapters detail the anatomy of the gastrointestinal tract, the relationship between gut bacteria and immunity, and common infections of the digestive tract. - Analytical Methods: The book explains techniques for analysing gut microbial populations to better understand their composition. - Nutritional Additives: A significant portion is dedicated to "bio-active" feed ingredients that support a healthy microbiome, including probiotics (live bacterial supplementation) and live yeast, prebiotics (gut-active carbohydrates) and enzymes, acids and phytogenics (botanicals). Author Expertise: W.N. Ewing: A doctor with over 20 years of experience researching bacterial supplements to improve animal performance. Lucy A. Tucker: A specialist with a PhD in monogastric nutrition and digestion from Harper Adams University College. -- "The knowledge of the gastro-intestinal microflora has substantially improved since 1994 and new methods for studying the microflora have been developed. There is now considerable emphasis on the use of alternatives to antibiotic growth promoters in animal production. This includes discussions of enzymes, oligosaccharides, probiotics and organic acids. This revised volume gives a modern understanding of the microflora in the gastro-intestinal tract and indicates how this can be managed in modern animal production without the reliance upon antibiotic growth promoters.
