Instant Insights: Dietary Supplements in Poultry Nutrition
Burleigh Dodds Science Publishing Limited (Verlag)
978-1-80146-427-7 (ISBN)
The first chapter reviews latest research on feed enzymes focussing on identifying the key challenges researchers face in terms of current trends in enzyme development, mechanism(s) of action and enzyme efficacy.
The second chapter considers the role of probiotics in optimising gut function in poultry. It reviews the development of novel, cost-effective, feed-stable, direct-fed microbials with potential for widespread utilisation and improved production.
The third chapter discusses the role of essential oils and botanicals in improving gut function in poultry, focussing on four major functions of phytobiotics that could potentially contribute to gut health: digestive conditioning, antimicrobial property, immunomodulation and gut microbiota modulation.
The fourth chapter considers the development of alternative protein sources for poultry nutrition, including grain by-products, pulses and algae. It also reviews best practices for improving the nutritive value of these alternative protein sources.
The final chapter reviews the effects of supplemental full- or de-fatted microalgal biomass in poultry diets on animal production and performance, meat and egg qualities, as well as nutrient metabolism and molecular responses.
Dr Guillermo Tellez Isaias worked at the National Autonomous University of Mexico for 16 years and was previously Head of the Avian Medicine Department at the College of Veterinary Medicine. Currently, Dr Tellez is a Research Professor at the Center of Excellence in Poultry Science, University of Arkansas, USA where his research is focused on the advantages of the poultry gastrointestinal model to evaluate the beneficial effects of functional foods to enhance intestinal health and disease resistance. Sahil Kalia is working as a Postdoctoral Associate in the Department of Animal Science at Cornell University. He has published various research articles, abstracts, book chapters in reputed journals including Nature Publishing Group. Dr Xin Gen Lei is Professor of Molecular Nutrition in the Department of Animal Science at Cornell University, USA. Professor Lei has an international reputation for his wide-ranging research in nutrition as well as algal biomass research. Amongst his many achievements, Professor Lei developed a new phytase enzyme that is now used in 46 countries to improve feed phosphorus bioavailability to animals and reduce their phosphorus excretion. He has won a number of awards from The American Society for Nutrition and the American Society of Animal Science. He is Associate Editor of the Journal of Nutrition as well as President of TEMA (Trace Elements in Man and Animals).
