About this book
Integrates principles and management techniques that apply to all grazing lands and to all grazing animals. This new edition 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; and Selecting plants and managing grazing lands.
