Book Description
From the PrefaceThe objective of this book is to review the basic knowledge and methodology of feeding grazing ruminants in tropical and semitropical countries. It is hoped this information will be of use to farmers, research specialists, teachers, students, extension specialists, feed manufacturers, and others throughout the world concerned with the nutrition of grazing ruminants. A unique feature is the identification of nutritional limitations of grazing ruminants in the tropics, which will be beneficial for increasing animal production efficiency through the application of improved nutrition. A large number of photographs illustrate nutritional deficiencies and conditions in tropical countries.This book contains 18 chapters concerned with the nutrition of grazing ruminants. The first chapter deals with the contributions, locations, and various types of ruminants and their importance to human welfare in the tropics and subtropics. Chapters 2 - 4 progress through nutrient requirements of grazing ruminants in warm climates, the effects of tropical heat on these requirements, and water requirements for ruminant species. Chapters 5 - 7 discuss grass and legume forage species suitable for tropical regions, pasture management procedures, and energy-protein supplementation programs needed during the extensive dry periods. The importance of tropical forages and soils toward meeting mineral requirements is discussed in Chapter 8. Chapters 9 -14 contain concise, up-to-date summaries of minerals emphasizing mineral status, incidence of mineral deficiencies and excesses in tropical regions, and benefits and methods of mineral supplementation for grazing ruminants are discussed in Chapters 15 - 17. Chapter 18 reviews vitamin nutrition considerations for ruminants consuming tropical forages.

Book Description
Forage in Ruminant Nutrition is the 12th text in a series of books about animal feeing and nutrition. The series is intended to keep readers updated on the developments occurring in these fields. As it is apparent that ruminant animals are important throughout the world because of the meat and milk they produce, knowledge about the feeds available to ruminants must also be considered for increased production and efficiency. This text provides information that readers will find considerably invaluable about forage feeds, such as grass, legumes, hay, and straw. The book is composed of 16 chapters that feature the following concepts of ruminant forage feeding: • composition of ruminant products and the nutrients required for maintenance and reproduction; • energy and nutrient available in forage: calcium, phosphorus, magnesium, sodium, copper, iodine, zinc, manganese, selenium, and cobalt; • intake of forage by housed ruminants; • grazing; • forage digestibility; • protein in ruminant nutrition; • protein and other nutrient deficiencies. This volume will be an invaluable reference for students and professionals in agricultural chemistry and grassland and animal husbandry researches.

Book Description
The fifth edition of this important book reviews recent advances in livestock mineral nutrition, updated throughout with new references that reflect the growing complexity of mineral metabolism. Major related themes covered include the assessment of the 'mineral value' of feeds, the false hopes placed on organic mineral supplements and limiting the 'mineral footprint' of livestock production to lower environmental pollution. Following a clear and easy to reference structure, the book also considers potential pitfalls, such as misleading estimates of mineral requirements for growth, and misinterpretation of genomic markers for mineral requirements and bioavailability of supplements. An essential resource for researchers and students in animal nutrition, agriculture and veterinary medicine, this book also forms a useful reference for veterinary practitioners and those concerned with human nutrition and environmental protection.

Book Description
This book is an up to date reference work covering all aspects of macro and trace element nutrition in farm livestock. Sufficient information is given on metabolism, functions and interactions to explain why needs, feeds and imbalances are not always easy to define or anticipate. The major emphasis is on the mineral nutrition of ruminant livestock since they are most likely to be affected by imbalances but where pigs and poultry are the more vulnerable, extensive coverage of the non-ruminant is given. This new edition of a highly successful text has been thoroughly revised and significantly expanded. Many chapters have been extensively updated and several chapters on new topics introduced. * Calcium, phosphorus, sodium and potassium are now treated separately * Over 40 new figures are presented, and extensive use made oftables to summarise important data * Chapters on trace elements have been drastically revised * Claims for enhanced availability for new chelated sources arecritically reviewed * Completely new chapters focus on: The unique need of the ruminant for elemental sulphur Occasionally beneficial elements and essentially toxic elements The improved conduct and interpretation of supplementation trials

Book Description
The INRA Feeding System for Ruminants has been renewed to better address emerging challenges for animal nutrition: prevision of productive responses, product quality, animal health and emissions to the environment, in a larger extent of breeding contexts. The new system is mainly built from meta-analyses of large data bases, and modelling. The dietary supply model accounts for digestive interactions and flows of individual nutrients, so that feed values depend on the final ration. Animal requirements account for variability in metabolic efficiency. Various productive and non-productive animal responses to diets are quantified. This book presents the whole system for dairy and meat, large and small ruminant production, including specificities for tropical and Mediterranean areas. The first two sections present biological concepts and equations (with their field of application and statistical accuracy) used to predict intake (including at grazing) and nutrient supply (Section 1), animal’s requirements and multiple responses to diets (Section 2). They apply to net energy, metabolisable protein and amino acids, water, minerals and vitamins. Section 3 presents the use of concepts and equations in rationing with two purposes: (1) diet calculation for a given performance objective; and (2) prediction of the multiple responses of animal to diet changes. Section 4 displays the tables of feed values, and their prevision. All the equations and concepts are embedded in the fifth version of INRAtion® software for practical use.
