Leading authorities from wide geographical regions of the globe will review the most up-to-date information in relation to temperate grasslands. Topics covered are: nutritive value of pasture; plant characteristics conducive to high animal intake and performance; modelling of both grass growth and animal production and intake in grazing systems; optimising financial returns from grazing; decision support systems; optimal animal breeds and traits for grazing systems; challenges and opportunities for animal production in the immediate future .In addition, short papers will present the most recent research on the above mentioned topics. One paper will present a comprehensive overview of animal production from pasture in Ireland This book will be of interest to grassland and ruminant production scientists, mathematical modellers working on grazing systems, extension workers, students of agriculture and animal production and progressive livestock farmers.
