Book Description
Geoffrey R. Dolby, PhD One of the principal characteristics of a scientific theory is that it be falsifiable. It must contain predictions about the real world which can be put to experimental test. Another very important characteristic of a good theory is that it should take full cognisance of the literature of the discipline in which it is embedded, and that it should be able to explain, at least as well as its competitors, those experimental results which workers in the discipline accept without dispute. Readers of John Parks' book will be left in no doubt that his theory of the feeding and growth of animals meets both of the above criteria. The author's knowledge of the literature of animal science and the seriousness of his attempt to incorporate the results of much previous work into the framework of the present theory result in a rich and imaginative integration of diverse material concerned with the growth and feeding of animals through time, a theory which is made more precise through the judicious use of mathematics. The presentation is such that the key concepts are introduced gradually and readers not accustomed to a mathematical treatment will find that they can appreciate the ideas without undue trauma. The key concepts are clearly illustrated by means of a generous set of figures. The crux of the theory comprises three differential Eqs. (7. 1-7.

Book Description
Nutrition is the key driver of animal health, welfare and production. In agriculture, nutrition is crucial to meet increasing global demands for animal protein and consumer demands for cheaper meat, milk and eggs and higher standards of animal welfare. For companion animals, good nutrition is essential for quality and length of life. Animal Nutrition examines the science behind the nutrition and feeding of the major domesticated animal species: sheep, beef cattle, dairy cattle, deer, goats, pigs, poultry, camelids, horses, dogs and cats. It includes introductory chapters on digestion and feeding standards, followed by chapters on each animal, containing information on digestive anatomy and physiology, evidence-based nutrition and feeding requirements, and common nutritional and metabolic diseases. Clear diagrams, tables and breakout boxes make this text readily understandable and it will be of value to tertiary students and to practising veterinarians, livestock consultants, producers and nutritionists.

Book Description
A detailed tracing, from acceptable sources, of archaeological and paleontologi cal discoveries made up to the present time leads us to suppose that approximate ly in 8000 y B. C., in Southern Turkestan, man succeeded in domesticating the first cattle, which he later took with him as he migrated from this remote region of Central Asia. Step by step, Europe and Asia have been gradually inhabited by domesticated cattle which have been incorporated into man's economy, both as a source of food and work. The same happened in America and Australasia, continents where cattle were taken by the European colonizing groups during the course of the 16th to the 18th centuries. Possibly the common cattle tick also reached these continents at the same time, accompanying its most frequent host. The cattle tick, Boophilus microplus, parasitizes Asiatic cattle races (with spe cial reference to the zebu, Bos indicus), but generally the level of infestation is not high, only a few engorged females being detected, generally no more than ten. When cattle of European races are infested by Boophilus microplus, how ever, the level of parasitism is higher, sometimes reaching limits incompatible with the life of the host.

Book Description
This book is developed from a British Society of Animal Science occasional meeting, held in September 2000. It brings together all of the scientific disciplines involved in the pre- and post-weaning biology of the piglet, concentrating on growth/development, nutrition, immunology/health, ethology and the physical environment.

Book Description
Following the success of Nutricines, the author considers the practical implications and implementation of the theories laid out therein. The strategic use of a wide variety of disease avoidance and health maintenance measures will contribute the an improved and more acceptable system of animal production without the use of antibiotic growth promoters.

Book Description
These proceedings contain 15 papers on the recent advances in pig and poultry mechanistic modelling. Notable among the papers is the consideration of new components of the animal production process, such as social stressors and disease. Understanding of some new systems such as the physiological control of egg production in hens by modelling is the given focus in one paper. The topics covered in the other papers include the following: introduction to modelling in the animal sciences, different approaches to modelling animal systems; basic concepts describing animal growth and feed intake; modelling populations for purposes of optimization; advancements in empirical models for prediction and prescription; nutrient flow models, energy transactions and energy feed systems; evaluation of animal genotypes through model inversion; considerations for representing microenvironmental conditions in simulation models for broiler chickens; use of physiological models to define environmental control strategies; comparison of pig growth models from the genetic point of view; model of metabolism in the sow; and place of models in the new technologies of production systems.
