Forages and grasslands play a unique role in agriculture because they contribute through animals to our food supply, and to the abatement of environmental problems. Interest in grassland management and grass utilization for dairy production in temperate and subtropical regions has recently led to considerable research efforts. In the past this research often emphasized on plant and animal aspects separately. However, the interrelationship between pasture and the grazing ruminant is a dynamic, two-way process. Product quality and a sustainable food chain of ruminant products are largely determined by animal nutrition, in which forage is the major feed source.
This book offers the contributions of active researchers and leading experts in the field of grassland management and grass utilization. Chapters are arranged in an order that allows progressive development within the food chain, moving from the big picture to basic principles of grassland management and effects on herbage quality, intake and nutrient flows. Rather than focus narrowly on soil-plant interactions, plant production, animal nutrition, animal production or product quality issues, this book takes a more in
