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.

This book presents strategies for feeding energy and protein supplements to pasture-fed dairy cows and examines the potential economic benefits. Effective supplementary feeding of concentrates is critical to the success of all dairy farms. This book is a substantially revised edition of 'Feeding Concentrates: Supplements for Dairy Cows' DRDC 1993. It focuses on feeding concentrates to pasture fed cows to achieve high milk production per cow per hectare, and will assist farmers to decide which supplements give the best results in their particular situation. The benefits that arise from supplementary feeding include higher stocking rates, promotion of growth in heifers and young cows; better body condition score and increased lactation length when pasture is less available; improved pasture use; reduced cost per tonne of pasture eaten; flexibility to increase milk production when milk prices are high; and increased milk protein content when the energy content in pasture is low. This edition has thoroughly reviewed the issues and clearly documents the results of research particularly for grains supplementation. The summaries and recommendations in each chapter will be particularly helpful to dairy farmers in making best management decisions relating to concentrate feeding.
