This book was released on 1976 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of the northern fowl mite, Ornithonyssus sylviarum (Canestrini and Fanzago), on body weight, reproductive potential and hematology of White Leghorn roosters were studied. Mean body weight was approximately 100 g. less for the mite infested roosters than for the uninfested roosters 4 weeks after they were infested with the northern fowl mite. Both groups increased in weight throughout the 26 weeks of the test but the differences in weight remained. Reproductive potential studies showed that after moderate populations of mites (101-1,000 mites/rooster) were observed, the volume of seminal fluid decreased. Four weeks before the test ended, one half of the infested roosters produced an average of less than 0.1 ml. of seminal fluid per week while the other half showed a decrease of 0.07 ml. in volume of seminal fluid produced when compared with the controls. Sperm concentration of mite infested roosters increased as the volume of seminal fluid decreased but was not statistically different from the controls. Motility and live/dead ratios of sperm did not show significant differences. Serum testosterone levels were statistically different between mite infested and control roosters. Hematology studies showed the greatest decrease in RBC and PCV occurred from the 4th to the 8th weeks when infestations were initially increasing rapidly. Mean Hemoglobin concentrations for the infested birds were consistently lower but not statistically different from the controls. No specific anemia could be attributed to mite populations as all hematological values were within normal ranges.

Download or read book Commercial Chicken Meat and Egg Production written by Donald D. Bell and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Commercial Chicken Meat and Egg Production is the 5th edition of a highly successful book first authored by Dr. Mack O. North in 1972, updated in 1978 and 1984. 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 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
Download or read book Parasites and Western Man written by R.J. Donaldson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to provide a concise account of those parasites which affect man in developed countries. Other textbooks relate mainly to the tropics and subtropics where parasites by comparison are more common. It is widely believed that this difference in prevalence between tropical and temperate countries is due to differences in climatic conditions alone. Whilst it is true that certain vectors can only act as transmitters of disease under climatic conditions found in the tropics, there are many other instances where climate per se is not a decisive factor. More often parasitic disease is related to the poor standards of hygiene, sanitation and nutrition, which characterize many of these tropical and subtropical areas. The advent of more international travel has added a new dimension to the study of parasites, with the appearance of rare and exotic parasitic infections in the West. This book encompasses the entire field of parasites in developed countries with a brief reference to other parts of the world whenever appropriate for the sake of completeness. Each chapter provides basic information as well as recent advances and current thinking. Thus the book will serve as an excellent, comprehensive in troduction to those taking up a specialized interest in the subject, as well as those who may wish to obtain general information but are not actively working in the field. Although it is primarily written from a medical and veterinary stand point, it provides valuable material for other disciplines.
