About this book
Leading authorities from wide geographical regions of the globe 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 p 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.
