Book Description
"An up-to-date review of the pasture and supplementary feed resources available to the New Zealand pastoral livestock industry, and the energy and protein requirements of these livestock. The interactions between animals and their feed resources ultimately determine both the quantity and quality of the feed consumed and thus the level of animal production. An understanding of this area is key to the successful allocation of feed resources. Although the principles discussed in the early chapters are common to all grazing animals, certain aspects of their application are species or system specific, and chapters address these issues. The environmental impact of grazing pastures and supplementing grazing animals is also addressed."--NZSAP Web site.

Book Description
A detailed study of grasslands and the management and investigation of grazing systems for animal production. The twenty-one chapters have been written by internationally recognized experts from Australia, the USA, the United Kingdom and New Zealand, and cover four main areas of interest. The first group of chapters is concerned with the evolution and ecology of grasslands and the behaviour of grazing animals. The second group deals in considerable depth with the intake of food and the nutritional value of different kinds of grassland (tropical, temperate and mediterranean), covering the most important tame' pastures. Arctic and multiple-purpose grazing are then discussed with emphasis on the social factors governing the use of resources. The following nine chapters deal with animal production technologies and management, including forage crops, fertilizer use, supplements for grazing animals, drought, detrimental substances in plants, and computer modelling of grazing systems. The final chapter integrates all this information and discusses the management of grazing systems, including decisions about subjects such as stocking rate and subdivision.

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
This text considers grazing management from the viewpoint of the ecology of grazing systems and focuses on the interrelationships between plant and animal populations which affect the stability of such systems, and the output of animal products from them. Relates the steps in the production process to the grassy surface characteristics that influence plant and animal behavior and uses these relationships to create a practical framework for management decisions.
