Mineral nutrition of livestock is an area of significant importance due to its contribution to farm animal economics and health. With a focus on macromineral utilization in farm animals, this book brings together quantitative aspects of phosphorus and calcium metabolism in farm animals in chapters written by leading researchers worldwide. It covers isotope dilution technique, phosphorus and calcium utilization in ruminants (sheep, goats and cattle) and non-ruminants (swine, horses) and recommended value of phosphorus and calcium inclusion in feed. It is an essential resource for researchers and students in animal sciences and nutrition.
