Doubly labelled water

Doubly labelled water is a highly effective technique for measuring the energy expenditure of an animal. Over the past decade this technique has enjoyed exponential growth, progressing from specialized to more routine use. Its application is widespread, broadly spanning the fields of animal ecology, agricultural nutrition and clinical nutrition. Divided into three parts, Doubly labelled water presents a clear and accessible account of this technique. Part One presents a general introduction to the study of animal energetics: Part Two discusses the theory behind use of doubled labelled water and Part Three evaluates the practical aspects of its use and the methodologies required for its application.
