Grazing animals need to be managed in order to accommodate desired results in terms of animal, plant, land and economic responses. Grazing Management, Second Edition integrates principles and management techniques that apply to all grazing lands and to all grazing animals. This comprehensive volume provides authoritative review on a wide range of relevant topics: animal nutrition and nutritional balance when fed on different sorts of grazing lands; seasonal variation and limits placed on ecosystems by grazing; the effects of grazing on grazing lands; the various sorts of grazing behaviors; selecting plants and managing grazing lands, as well as many other important topics bearing upon the methods, practises and procedures for properly managing grazing lands and animals.

Key Features

  • Animal nutrition and nutritional balance when fed on different sorts of grazing lands
  • Seasonal variation and limits placed on ecosystems by grazing
  • The effects of grazing on grazing lands
  • The various sorts of grazing behaviours
  • Selecting plants and managing grazing lands


Faculty, researchers, graduate students, land managers, and extension services personnel responsible for grazing and rangeland management for both wild and domestic animals. Federal, state, and local departments of agriculture. Libraries at institutions with strong animal science, animal nutrition, land management, and land grant backgrounds. Grazing Management is recommended as both a textbook and as a reference manual. As a textbook, the prime audience is 4th & 5th year university students with a major in range science, animal science, big game management, or agronomy. As a reference manual, it will be utilized by extension and research personel, grazing land managers, innovative ranchers and farmers, agribusiness personnel and conservationists.
