Control and Manipulation of Animal Growth explores the development and growth of animals. The reproductive system of animals is also discussed, along with how its development can be accelerated. The topic is presented using various studies by the authors together with a number of references to other books and studies. This book contains 20 chapters and revolves around the advancement of an animal's growth hormone. It explains how gender plays a part in an animal's development and talks about factors that can affect the process, such as environment, temperature, and food intake. This book also discusses bone growth, fetal growth, metabolism, factors of epidermal growth, growth manipulation, growth hormones, hormonal manipulation, and the effect of insulin. This text covers a wide range of facts and investigations and can therefore serve as an excellent reference for people who want to study an animal's internal and external development.

This book describes the cellular and molecular mechanisms that control farm animal growth, includingdevelopment and body composition. The emphasis is on circulating hormones, local growth factors andgene transcription factors which regulate growth and differentiation of skeletal muscle, bone andadipose tissue. Overall, this book will be an important resource for students that have a limitedbackground in cell, molecular and developmental biology and the effect of endocrine and growthfactors on the growth process.

The biotechnological advances of recent years have put us on the brink of unprecedented gains in animal productivity. Manipulation of animal growth rate and composition of gain is now possible by a variety of techniques. Ex amples include ingestion of beta-adrenergic agonists, injection of somatotropin, castration, immunization, and gene insertion. Animal Growth Regulation ad dresses modem concepts of growth regulation with an emphasis on agricul turally important animals. This emphasis is not exclusive, as many situations exist in which the only information available was generated in other species, and this information has been included for the sake of clarity and completeness. However, because of the overall orientation of this volume, particular attention has been given to the regulation of skeletal muscle, adipose tissue, and bone growth. Certain hormones and growth factors have a profound influence on growth regulation and this basic physiological knowledge is being harnessed to maniplilate growth. Thus, considerable emphasis has been given to growth hor mone-somatomedinlinsulinlike growth factor regulation of cell and tissue growth. The involvement of peptides coded by protooncogenes and of negative growth regulators, such as transforming growth factor-l3, represents an emerging area of molecular biology wherein basic knowledge offers potential exploitation for growth manipulation. Opportunities also exist for regulation of protein turn over, especially from the standpoint of protein degradation. Therefore, a place was reserved for these topics in order to provide relevant basic knowledge.

The Control of Fat and Lean Deposition is a collection of papers dealing with the methods of influencing fat and lean deposition in whole animals, such as the use of the immune response, the use of exogenously applied materials, transgenesis, or the diet itself. The papers also consider the results of fat manipulation and lean deposition on meat quality to achieve suitabilty for human consumption. Some papers review the hormonal regulation of muscle protein synthesis, degradation, and cell growth, noting that muscle protein turnover involves the regulation of cellular growth and metabolism of the whole body. Another paper investigates the surge in lipid accumulation during fattening, as well as the correlation between changes in flux or enzyme activities in growing animals to changes in lipid accretion. One paper examines the responsiveness of prenatal development of key tissues, such as skeletal tissue and adipose, to nongenetic influences. The paper also analyzes how such responsiveness influence the rate and composition of postnatal growth. Another paper discusses the observation that reducing fat content especially on the muscle tissue itself can adversely affect the eating quality and tenderness of meat. The collection is suitable for veterinarians, livestock growers, and researchers engaged in food processing and preservation.

An understanding of the processes that change the shape and composition of farm animals is fundamental to all aspects of production. Updated to include new chapters on avian growth and global warming, and citing new research throughout, this comprehensive textbook provides key information on how animals grow and change in shape and composition, and the factors that affect these processes. Presented in a larger format with new photographs and focus boxes, this third edition continues to fill the important role of helping to understand how the basics of growth must be thoroughly understood if farm animals are to be used efficiently and humanely in producing food for mankind.

The Endocrinology of Growth, Development, and Metabolism in Vertebrates provides an overview of vertebrate endocrinology. This book aims to strengthen the bridge between medical and comparative endocrinologists by addressing the benefits that they can derive from this association. Organized into five parts encompassing 24 chapters, this volume starts with a discussion on the structure and biological function of growth hormone (GH) and prolactin (PRL) family. This book then explains the extrinsic, genetic, and humoral factors that influence animal growth, particularly in poikilotherms. This text also elaborates the environmental conditions that affect the growth of poikilotherms, including food availability, temperature, and photoperiod. Other chapters discuss how somatotropin affects the growth development in homeotherms, such as livestock species. The reader is also introduced to the metabolic actions of GH, which can be described in terms of short-lived insulin-like effects. Endocrinologists, molecular endocrinologists, biologists, molecular biologists, biochemists, researchers, and physicians will find this book extremely useful.

Biotechnology in Growth Regulation focuses on mechanisms of action of growth hormones and how immunological and transgenic procedures can affect growth response. The book first examines species specificity and structure-function relationship of growth hormones. Microheterogeneity of growth hormones; variations in amino acid sequence and biological properties of growth hormones; and structure-function relationship are discussed. The text also looks at growth hormone receptors and binding proteins; regulation of growth hormone receptors; modulations of growth hormone release; and neuroregulation of growth hormone secretion. The book then discusses the role of growth hormones in the regulation of adipocyte growth and function. Chronic effects of growth hormones on insulin action and lipid synthesis; effects of growth hormones on lipolysis; and adipogenesis are also described. The text looks at growth-promoting properties of recombinant growth hormones and mechanisms by which porcine growth hormone enhances growth in pigs. The book also highlights the direct effects of growth hormones on osteogenesis and chondrogenesis; action of IGF-I on mammary function; antigen-antibody complexes that enhance growth; and transgenics. The text also presents experiments that show the effects of growth hormones on animals. The book is a good source of information for readers wanting to study growth hormones.

The publication of the Department of Health White Paper "The Health of the Nation" (1992) and "Our Healthier Nation" (1998) gave emphasis to the importance of nutritional health of the nation at all ages. It is clear that the achievement of specific targets for pregnancy and infancy as set out in the White Paper will involve the training of all health care professionals in nutrition education. This book responds to the challenge and focuses on good nutrition for and during pregnancy, in low birth-weight infants, and during infancy. It has a strong public health emphasis, dealing with health prevention issues for the Nation's younger population. The text is written as a scientific reference book for those seeking to apply science in the support of a successful pregnancy and in the prevention of nutritional problems during foetal and early post-natal life. The importance of optimal nutrition during these periods of life is emphasised by the overwhelming evidence that nutritional problems in early embryonic life may cause congenital malformations and during late foetal life and early post natal life may set the molecular programme for later disease development.
