Feeding of Non-ruminant Livestock


Book Description

Feeding of Non-Ruminant Livestock focuses on the nutrition of non-ruminant livestock. The book first discusses the feeding of non-ruminants, including regulation of feed intake and intake requirements and recommendations. The text highlights the energy value of feeds for non-ruminants; protein, vitamin, mineral, and nutrition of non-ruminants; and nutrition of rabbits. The book also underscores the nutrition of growing and breeding pigs, including gilts, boars, and sows. The text describes the nutrition of rapidly growing broilers. Presentation of diets and choice of energy level; proteins and amino acids; characteristics of production system; and mineral, vitamins, and additives are considered. The book also discusses the nutrition of laying hens and turkeys. Nutrition of rearing pullets; nutrition of hens during lay; meat turkeys; and nutrition of breeder turkeys during rearing are described. The text also highlights the nutrition of ducks, Japanese quails, and roasting geese. The book is a good source of information for readers wanting to study the nutrition demands of non-ruminant livestock.










Microbial Symbioses


Book Description

Plants and animals have evolved ever since their appearance in a largely microbial world. Their own cells are less numerous than the microorganisms that they host and with whom they interact closely. The study of these interactions, termed microbial symbioses, has benefited from the development of new conceptual and technical tools. We are gaining an increasing understanding of the functioning, evolution and central importance of symbiosis in the biosphere. Since the origin of eukaryotic cells, microscopic organisms of our planet have integrated our very existence into their ways of life. The interaction between host and symbiont brings into question the notion of the individual and the traditional representation of the evolution of species, and the manipulation of symbioses facilitates fascinating new perspectives in biotechnology and health. Recent discoveries show that association is one of the main properties of organisms, making a more integrated view of biology necessary. Microbial Symbioses provides a deliberately "symbiocentric outlook, to exhibit how the exploration of microbial symbioses enriches our understanding of life, and the potential future for this discipline. - Offers a concise summary of the most recent discoveries in the field - Shows how symbiosis is acquiring a central role in the biology of the 21st century by transforming our understanding of living things - Presents scientific issues, but also societal and economic related issues (biodiversity, biotechnology) through examples from all branches of the tree of life










In Vitro Digestibility in Animal Nutritional Studies


Book Description

This book addresses various aspects of in vitro digestibility: • Application of meta-analyses and machine learning methods to predict methane production; • Methane production of sainfoin and alfalfa; • In vitro evaluation of different dietary methane mitigation strategies; • Rumen methanogenesis, rumen fermentation, and microbial community response; • The role of condensed tannins in the in vitro rumen fermentation kinetics; • Fermentation pattern of several carbohydrate sources; • Additive, synergistic, or antagonistic effects of plant extracts; • In vitro rumen degradation and fermentation characteristics of silage and hay; • In vitro digestibility, in situ degradability, and rumen fermentation of camelina co-products; • Ruminal fermentation parameters and microbial matters to odd- and branched-chain fatty acids; • Comparison of fecal versus rumen inocula for the estimation of NDF digestibility; • Rumen inoculum collected from cows at slaughter or from a continuous fermenter; • Seaweeds as ingredients of ruminant diets; • Rumen in vitro fermentation and in situ degradation kinetics of forage Brassica crops; • In vitro digestibility and rumen degradability of vetch varieties; • Intestinal digestibility in vitro of Vicia sativa varieties; • Ruminal in vitro protein degradation and apparent digestibility of Pisum sativum; • In vitro digestibility studies using equine fecal inoculum; • Effects of gas production recording system and pig fecal inoculum volume on kinetics; • In vitro methods of assessing protein quality for poultry; and • In vitro techniques using the DaisyII incubator.




Fundamentals of Animal Nutrition


Book Description

The book provides comprehensive information about the different aspects of veterinary nutrition in tropical countries.The introductory chapter discuss the importance of nutrition, feeds and feeding of balanced and optimum feeds specifically required for the sustenance of life. The second chapter, discusses briefly the history of research in animal nutrition.The book further talks about the relationship between the environment and nutrition in animals; the chemical composition of plants and animals; and the various sources of feed for animals. It provides details on the different phases of life cycle in animals, and the effect of nutrition on the performance. Various Nutrients and its importance in livestock nutritionand production has been illustrated in details. Various nutrients such as water, carbohydrate, protein, fats, vitamins, minerals etc are individually dealt in a separate chapter. The digestive system,digestion and metabolism of carbohydrates, protein and fats in ruminant and non ruminant livestock have been illustrated. A dedicated chapter fully describes the activity of enzymes which are directly involved in nutrition. Also this book deals with the harmful components of animal feed which are found mainly in the unconventional feeds. The books also provide chapters like partitioning of feed& energy and also the therapeutic and clinical nutrition which are very importantfor the under graduate & post graduate students and researchers of animal nutrition and livestock production and management. This book is useful for researchers, undergraduate and post graduate students studying veterinary sciences, animal husbandry, zoology and biochemistry.




Nutritional Ecology of the Ruminant


Book Description

This monumental text-reference places in clear persepctive the importance of nutritional assessments to the ecology and biology of ruminants and other nonruminant herbivorous mammals. Now extensively revised and significantly expanded, it reflects the changes and growth in ruminant nutrition and related ecology since 1982. Among the subjects Peter J. Van Soest covers are nutritional constraints, mineral nutrition, rumen fermentation, microbial ecology, utilization of fibrous carbohydrates, application of ruminant precepts to fermentive digestion in nonruminants, as well as taxonomy, evolution, nonruminant competitors, gastrointestinal anatomies, feeding behavior, and problems fo animal size. He also discusses methods of evaluation, nutritive value, physical struture and chemical composition of feeds, forages, and broses, the effects of lignification, and ecology of plant self-protection, in addition to metabolism of energy, protein, lipids, control of feed intake, mathematical models of animal function, digestive flow, and net energy. Van Soest has introduced a number of changes in this edition, including new illustrations and tables. He places nutritional studies in historical context to show not only the effectiveness of nutritional approaches but also why nutrition is of fundamental importance to issues of world conservation. He has extended precepts of ruminant nutritional ecology to such distant adaptations as the giant panda and streamlined conceptual issues in a clearer logical progression, with emphasis on mechanistic causal interrelationships. Peter J. Van Soest is Professor of Animal Nutrition in the Department of Animal Science and the Division of Nutritional Sciences at the New York State College of Agriculture and Life Sciences, Cornell University.
