Download or read book Reproduction in Poultry written by Robert J. Etches and published by Cabi. This book was released on 1996 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the biological basis of reproduction in poultry and places this information in the context of poultry production. The author has collated and integrated recent information from a variety of sources in order to highlight the principles of the reproductive biology of poultry. This is achieved through a well-illustrated and tabulated text which emphasizes integration rather than comprehensive literature citations. The book begins by considering the egg, proceeds to a brief description of embryonic and chick development as they relate to poultry production, and describes the physiological processes that lead to formation of the fertile egg. It concludes with a discussion of the relationship between measurements of reproductive success that are commonly used in the poultry industry and their ability to reflect the physiological processes that contribute to successful reproduction. The book is aimed at advanced undergraduates or graduate students studying animal reproduction or agriculture, as well as scientists working in the poultry industry.

Download or read book Reproduction in Poultry written by Ifeanyi Charles Okoli and published by . This book was released on 2021-02-05 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Poultry is an integral part of animal agriculture, and they provide the human population with products such as meat and eggs. In poultry production, as with other livestock systems, a high level of reproductive performance is absolutely crucial to efficient production. In order to manage poultry reproduction and the specific problems that arise, it is important to understand the underlying physiology of the reproductive process. Thus, this book aims to provide an integrated overview of the subject of poultry reproduction, describing the normal function of the reproductive system. The book is designed to provide a general background to the field of poultry reproduction for postgraduate and undergraduate students, and a reference source for research scientists and professional workers in the field related to the production of animal products. The book will serve as an introductory text to veterinary students embarking on a career in reproductive physiology research. Furthermore, we hope that it will be used by working veterinarians and farmers to update themselves on new research findings and developments in the management of poultry reproduction. Since the mid the 19th century, several studies characterizing the anatomy and physiology of the male and female reproductive systems of poultry have been conducted. This book focuses mainly on the review of current literature on physiological mechanisms regulating reproduction with emphasis on poultry species. It describes the basic structures and functions of the male and female reproductive tracts including the sex organs (testis, ovary), excurrent ducts, accessory organs, oviducts, shell gland and vagina. The endocrine glands that control reproduction in poultry were also described. The process of sperm production and egg formation are discussed including highlights of the recent literature on factors that affect spermatozoa production and function. The basic fundamental structure and chemical characteristics of the eggs were defined. Key elements of the egg production are discussed including synthesis and transfer of egg yolk constituents, the formation of the egg yolk in the ovary, development of oocytes and ovulation, the formation of egg white and chalazae, the formation of eggshell and oviposition. This section also described in detail the sperm-egg binding, sperm acrosome reaction and protease enzymes required for the hole formation in the perivitelline membrane and the development of the diploid zygote emanated from the fusion of the nuclei from both male and female gametes. The editors have succeeded in bringing together many renowned poultry reproduction experts to review the current body of knowledge in poultry reproduction and are grateful to all the authors for their state of the art compilation of the most recent development in this field. We feel that we have achieved our goal of producing an outstanding book, with the top scientists in their field addressing each subtopic. I.P. OgbuewuI.C. OkoliM.U. Iloeje

Download or read book Undernutrition of Growing Male Chickens and Its Relationship to Sexual Development and Reproductive Performance written by Jack Edenfield Jones and published by . This book was released on 1966 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: A major economic loss in the poultry industry is the large nu-Tiber of infertile eggs among those eggs produced for hatching purposes. Major studies have been undertaken to establish production procedures to minimize infertility, especially in females. Male fertility rapidly declines with age causing some breeder males to be replaced in mid-season. It is common practice to raise breeder cockerels together with breeder pullets since their requirements have been assumed to bo the same. However, very little research has been undertaken to study the requirements of cockerels for optimum reproduction performance. Restriction of nutrients to reduce growth in pullets has been practiced for many years. The purpose of this restriction is to delay sexual maturity, reduce mortality, and increase initial egg size with more uniform size during the laying period. This has been accomplished with no permanent effect on fertility. The purpose of this research was to study the effect of one type of feed restriction, low dietary protein levels during the growing period, upon development of the reproductive system of cockerels as indicated by subsequent reproductive performance and morphology of the testes.

Download or read book Avian Immunology written by Bernd Kaspers and published by Academic Press. This book was released on 2012-12-02 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of Avian Immunology provides an up-to-date overview of the current knowledge of avian immunology. From the ontogeny of the avian immune system to practical application in vaccinology, the book encompasses all aspects of innate and adaptive immunity in chickens. In addition, chapters are devoted to the immunology of other commercially important species such as turkeys and ducks, and to ecoimmunology summarizing the knowledge of immune responses in free-living birds often in relation to reproductive success. The book contains a detailed description of the avian innate immune system, encompassing the mucosal, enteric, respiratory and reproductive systems. The diseases and disorders it covers include immunodepressive diseases and immune evasion, autoimmune diseases, and tumors of the immune system. Practical aspects of vaccination are examined as well. Extensive appendices summarize resources for scientists including cell lines, inbred chicken lines, cytokines, chemokines, and monoclonal antibodies. The world-wide importance of poultry protein for the human diet, as well as the threat of avian influenza pandemics like H5N1 and heavy reliance on vaccination to protect commercial flocks makes this book a vital resource. This book provides crucial information not only for poultry health professionals and avian biologists, but also for comparative and veterinary immunologists, graduate students and veterinary students with an interest in avian immunology. With contributions from 33 of the foremost international experts in the field, this book provides the most up-to-date review of avian immunology so far Contains a detailed description of the avian innate immune system reviewing constitutive barriers, chemical and cellular responses; it includes a comprehensive review of avian Toll-like receptors Contains a wide-ranging review of the "ecoimmunology" of free-living avian species, as applied to studies of population dynamics, and reviews methods and resources available for carrying out such research

The 4th edition was co-authored with Donald D. Bell in 1990. The book has achieved international success as a reference for students and commercial poultry and egg producers in every major poultry producing country in the world. The 5th edition is essential reading for students preparing to enter the poultry industry, for owners and managers of existing poultry companies and for scientists who need a major source of scientifically based material on poultry management. In earlier editions, the authors emphasized the chicken and its management. The 5th edition, with the emphasis shifted to the commercial business of managing poultry, contains over 75% new material. The contributions of 14 new authors make this new edition the most comprehensive such book available. Since extensive references are made to the international aspects of poultry management, all data are presented in both the Imperial and Metric form. Over 300 tables and 250 photos and figures support 62 chapters of text. New areas include processing of poultry and eggs with thorough discussions of food safety and further processing. The business of maintaining poultry is discussed in chapters on economics, model production firms, the use of computers, and record keeping. Updated topics include: breeders and hatchery operations; broiler and layer flock management; replacement programs and management of replacements; nutrition; and flock health. New chapters address flock behavior, ventilation, waste management, egg quality and egg breakage. Other new features include a list of more than 400 references and a Master List of the tables, figures, manufacturers of equipment and supplies, research institutions, books and periodicals, breeders, and trade associations. Commercial growers will find the tables of data of particular interest; scientists will be able to utilize the extensive references and to relate their areas of interest to the commercial industry's applications; and students will find that the division of the book into 11 distinct sections, with multiple chapters in each, will make the text especially useful.

Download or read book Physiological Adaptations for Breeding in Birds written by Tony D. Williams and published by Princeton University Press. This book was released on 2012-08-05 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physiological Adaptations for Breeding in Birds is the most current and comprehensive account of research on avian reproduction. It develops two unique themes: the consideration of female avian reproductive physiology and ecology, and an emphasis on individual variation in life-history traits. Tony Williams investigates the physiological, metabolic, energetic, and hormonal mechanisms that underpin individual variation in the key female-specific reproductive traits and the trade-offs between these traits that determine variation in fitness. The core of the book deals with the avian reproductive cycle, from seasonal gonadal development, through egg laying and incubation, to chick rearing. Reproduction is considered in the context of the annual cycle and through an individual's entire life history. The book focuses on timing of breeding, clutch size, egg size and egg quality, and parental care. It also provides a primer on female reproductive physiology and considers trade-offs and carryover effects between reproduction and other life-history stages. In each chapter, Williams describes individual variation in the trait of interest and the evolutionary context for trait variation. He argues that there is only a rudimentary, and in some cases nonexistent, understanding of the physiological mechanisms that underpin individual variation in the major reproductive life-history traits, and that research efforts should refocus on these key unresolved problems by incorporating detailed physiological studies into existing long-term population studies, generating a new synthesis of physiology, ecology, and evolutionary biology.

This book was released on 2013-10-29 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: ​​​​​​​​​​​This book addresses the impacts of current and future reproductive technologies on our world food production and provides a significant contribution to the importance of research in the area of reproductive physiology that has never been compiled before. It would provide a unique opportunity to separate the impacts of how reproductive technologies have affected different species and their contributions to food production. Lastly, no publication has been compiled that demonstrates the relationship between developments in reproductive management tools and food production that may be used a reference for scientists in addressing future research areas. ​During the past 50 years assisted reproductive technologies have been developed and refined to increase the number and quality of offspring from genetically superior farm animal livestock species. Artificial insemination (AI), estrous synchronization and fixed-time AI, semen and embryo cryopreservation, multiple ovulation and embryo transfer (MOET), in vitro fertilization, sex determination of sperm or embryos, and nuclear transfer are technologies that are used to enhance the production efficiency of livestock species.
