Growth In Animals

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.

An understanding of the processes which change the size, shape, and composition of farm animals is fundamental to all aspects of production which seeks to meet human dietary and other needs. This book provides, within the limits of a student text, a broad review of how animals grow and change in shape and composition, as well as those factors which affect growth processes and which dictate the extent and direction of changes within the animal. The presentation progresses from cell to tissue to entire animal and includes a description of those factors within the animal, particular genes, hormones, and gender, which fashion this progression, and how efficiency for production can be maximized. The main focus is on classical principles of growth and its measurement rather than on topics such as growth manipulation or molecular biology. Most of the information focuses on farm mammals, particularly cattle, sheep, and pigs. The book fills a gap in the literature by taking the reader from cell to complete animal, based on original anatomical studies and quantitative approaches which have been developed subsequently. It presents a core text for advanced undergraduate courses in animal science and production, and will be an essential acquisition for librarians in agriculture and veterinary science.

The Science of Animal Growth and Meat Technology, Second Edition, combines fundamental science- based and applied, practical concepts relating to the prenatal and postnatal growth of cattle, sheep and pigs. It provides the necessary components to understand the production and growth of livestock for safe and quality meat products and presents an understanding of the principles of meat science and technology that is needed to understand the meat industry. Information on the slaughter process of animals, muscle structure and meat tenderness, meat quality, meat safety, and microbiology makes this a valuable self-study reference for students and professionals entering the field. Describes principles in muscle metabolism, meat quality and meat safety using case studies Discusses the microbial safety of meat products, primary pathogens of concern, and pathogen detection Offers solutions on how to control bacterial growth to improve the safety and quality of meat Presents a new chapter on packaging for meat and meat products that focuses on flexible film technology, packaging materials and equipment technology Includes new information on inspection systems prior to slaughter, during slaughter, and the inspection of meat processing systems

The book is intended to provide in-depth reviews of the recent advances in major areas of metabolism in growing domestic animals. The study of metabolism represents a nexus of biological phenomenon that integrates the impact of nutrition, physiology, endocrinology, immunology, biochemistry, and cell biology in an organism. The development of new methodological techniques and experimental approaches have provide scientists with a greater understanding of how key nutrients or substrates are metabolized at the cellular, organ, and whole animal level. This book presents contributions from leading scientists in nutrition and physiology that highlight important new developments in interorgan and tissue-specific metabolism of protein and amino acids, lipids and fatty acids, and carbohydrates in monogastric and runinant species. Authors will describe the impact of specific biochemical pathways and expression of critical enzymes, routes of nutrient or substrate input, and anatomical or structural influences on the rates of metabolism in a given tissue or cell type. Major substrates/ fuels for oxidative metabolism, key signaling pathways, and intracellular molecules that regulate the major metabolic processes will be described. Also included is how the metabolism of growing animals is influenced by ontogeny, stage of differentiation, and major changes in diet, or the environment. The concepts and specific findings in each area are discussed in the context of their impact on the nutrient requirements, growth, environmental impact, healt and well-being of animals. The book will be a useful reference for research scientists, teachers and students interested in and advanced understanding of metabolism in growing animals. The book is written by leading experts and highlights some of the most recent advances in the field of metabolism. It is a useful reference for researchers and advanced level graduate students in nutrition, physiology and animal science. Presents recent advances in the field of metabolism.

Shows how different animals grow and change.

Studies in the Agricultural and Food Sciences: Growth in Animals discusses the more advanced concepts of growth, its changes and effects on different animals and systems, and its implications for agriculture. Based on a symposium of the same name, the book defines growth and its effects on the whole body; the biochemical and genetic determinants that affect it; and the effect of thermal environment on growth and its relation with immunity. Growth of bones, muscle nucleic acid and protein, and adipose tissue are also explained. The text also encompasses the relation of growth and gut microflora; the effects of growth-promoting agents in ruminant animals and single-stomach animals; and growth and breeding performance in animals. The growth in mammals and birds for meat production and its effects on the meat quality of animals are also covered in this book. This monograph is recommended for those who would want to start or are currently running animal and poultry farms, as well as for scientists who wish to study the phenomenon of growth for the betterment of agriculture.
