This book with eighteen chapters draws together themes on sustainability that have emerged as the most pressing in recent years. The book addresses practical topics such as air quality, manure management, animal feeds, production efficiency, environmental sustainability, biotechnology issues,...

This chapter discusses the production efficiency of ruminants, particularly cattle, in relation to feeds, nitrogen excretion and methane emission. Focus is given on the production efficiency of cattle, primarily that of dairy cattle, at the animal level. Improvements in production efficiency are...

The calcium and phosphorus requirements of cattle, sheep and goats are discussed, with emphasis on the regulatory aspects, phosphorus content of feed and avoidance of overfeeding to reduce the phosphorus content of faeces.

This chapter describes the use of the isotope dilution technique to study phosphorus metabolism in pigs, horses and poultry and calcium utilization in horses.

This chapter describes the use of the isotope dilution technique and models to study phosphorus metabolism in livestock.

The results of studies on the requirements, bioavailability, absorption and excretion of calcium and phosphorus in sheep, goats and cattle determined using the isotope dilution technique are presented.

This chapter provides an overview of the phosphorus and calcium metabolism and excretion in livestock and the environmental impact of these nutrients.

This book contains 10 chapters that discuss phosphorus and calcium metabolism, efficiency of utilization, availability, requirements and excretion in livestock and environmental impact.

This chapter presents ways to improve the production efficiency and reduce the excretion of primarily nitrogen (N) and phosphorus (P), but also other undesired substances such as heavy metals in monogastric animals and emissions of ammonia and methane. The two main areas addressed are the amount of ...

This chapter discusses how one can define sustainability and how it is achieved or even if it can be achieved. The chapter frames sustainability as one type of 'wicked problem' that cannot be solved, only managed. Two examples are offered of multi-stakeholder innovation processes that have in their ...
