The first edition of this book, published in 1993, was very well received as providing a comprehensive review of the digestion and metabolism of ruminant animals. Since its publication, much new research has been conducted in the subject and knowledge has increased. This is incorporated in this second edition through the addition of five completely new chapters. These cover: the gas production technique in feed evaluation, calorimetry, the relationship between pasture characteristics and animal performance, feed processing and the integration of data in feed evaluation systems. Other chapters have been fully expanded and updated as appropriate and Dr. Dijkstra has also been enrolled as the lead editor. This book brings together quantitative approaches used in the study of mechanisms of ruminant digestion and metabolism.

Mathematical modeling is increasingly applicable to the practical sciences. Here, mathematical approaches are applied to the study of mechanisms of digestion and metabolism in primary animal species. Farmed animals - ruminants, pigs, poultry and fish - are comprehensively covered, as well as sections on companion animals. Common themes between species, such as energy and amino acid metabolism, are explored with a worldwide approach. Leading researchers from around the world have contributed to France and Kebreab's volume to provide an integrated approach to mathematical modelling in animal nutrition.

Written by leading researchers from the USA, Canada and Europe, this is an essential reference tool for researchers and advanced students in animal nutrition. Farm livestock have evolved digestive systems that are capable of digesting fibrous materials and by-products unsuited for man. Throughout the world, production from farm livestock is concerned with providing food and clothing of animal origin for man. Animal production science underpins this goal and provides the scientific basis for livestock management practices. Feed evaluation concerns the use of methods to describe animal feedstuffs with respect to their ability to sustain different types and levels of animal performance. The main themes of the book are methods of feed evaluation, current feeding systems, and mechanistic mathematical modeling. No other title brings together methods, systems and models under one cover.

Evidence for childhood and youth from the sixth century to the sixteenth, but with particular emphasis on later medieval England. Moving on from the legacy of Aries, these essays address evidence for childhood and youth from the sixth century to the sixteenth, but with particular emphasis on later medieval England. The contents include the idea of childhoodin the writing of Gregory of Tours, skaldic verse narratives and their implications for the understanding of kingship, Jewish communities of Northern Europe for whom children represented the continuity of a persecuted faith, children in the records of the northern Italian Humiliati, the meaning of romance narratives centred around the departure of the hero or heroine from the natal hearth, the age at which later medieval English youngsters left home, how far they travelled and where they went, literary sources revealing the politicisation of the idea of the child, and the response of young, affluent females to homiletic literature and the iconography of the virgin martyrs in the later middle ages.

This is a new release of the original 1948 edition.

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.

Bringing together the disciplines of agriculture, animal science, plant science and ecology, this book explores how mathematics can be used to understand and explain agricultural processes. It starts by providing a review of the mathematical models currently available to agriculturalists, and the philosophy behind, and objectives of, modeling. The book then applies these techniques to real-life problems faced by people managing crops and animals, including the influence of digestion on animal growth rates and levels of photosynthesis on crop yield.
