Ultrasonography And Reproduction In Swine

Covering horse, cattle, sheep, goat, swine and the dog and cat, this volume offers a comprehensive and illustrated account of veterinary gynaecologic examination and reproduction. Staring with the common indications for ultrasonography, gynaecologic and obstetric examination, the book goes on to address the interpretation of ultrasonographic findings. The pregnant and non-pregnant uterus, pathologic changes of the uterus and other abnormal ultrasonographic findings are described and explained. Features include: illustrations which aim to facilitate accurate and rapid decision-making; focus on technique, as well as interpretation; and coverage of ovarian tumours and cysts. The book is intended for veterinarians.

A guide to the reproductive problems facing the busy veterinary practitioner in every day practice. The pregnant and non-pregnant uterus, as well as pathologic changes of the reproductive system are described and explained. The book is superbly illustrated and covers all the important domestic large and small animals: dogs, cats, horses, cows, sheep, goats and pigs.

The use of ultrasonic imaging techniques for diagnostic purposes in veteri nary medicine and animal science has lagged far behind their use in human medicine. In the area of domestic animal reproduction, diagnostic ultrasono graphy has a relatively short history. Reports on B-mode scanning first appeared as late as 1969, when Stouffer and co-workers used it for counting foetal numbers in late gestation sheep. After Lindahl had re-evaluated the potential of two-dimensional ultrasonography for pregnancy diagnosis in sheep in 1976, results of the first large scale field-trials by Fowler and Wilkins on predicting foetal numbers during the first half of gestation in sheep were published as recently as 1980. In this year also the first paper, by Palmer and co-workers, on ultrasonic scanning of the uterus and ovaries in the mare appeared. The improvement of diagnostics which was achieved by the application of this technique is illustrated by its present routine use in clinical equine practice and sheep breeding. Besides offe ring an accurate early pregnancy diagnosis in species such as the horse, cow, sheep, goat, pig and dog, ultrasonography enables the visualization of ovarian and uterine structures for the identification of both physiological and pathological conditions. In this way it replaces or supplements the more common diagnostic techniques used by the general practitioner so far. Ultrasonography has also opened several new lines of research for clini cians and research workers.

An understanding of sustainability in animal production is becoming increasingly necessary since the global demand for food is expected to dramatically increase in the coming decades. In this context, raising animals for the production of food will become increasingly challenging. Farm animals should not adversely compete with humans for their own sustenance, and food of animal origin should be safe and affordable. The production of healthy animals will therefore be a prerequisite. Such animals will efficiently convert their feed into food that can be certified as nutritive and safe. In addition there is growing evidence that there should be a focus on animal welfare, and environmental pollution related to animal farming must be minimized. Indeed the equation to resolve the constraints on animal production is complex and multifactorial. It is inarguable that the environment and the feed that is offered to animals, are key elements of sustainability in livestock and poultry production. This book addresses the major issues related to animal health and welfare maintenance in relation to their environment, as well as housing emissions and waste management. Experiments, reviews and expert opinions and scenarios for the future are presented. Each of the chapters has been written by scientists with international reputations. The language used, and the examples and the illustrations provided, make it easy to read. The book is of major and current interest to teachers and students in animal and veterinary sciences and to professionals: veterinarians, farm managers, agricultural advisers worldwide.

An essential resource for both students and practitioners, this comprehensive text provides practical, up-to-date information about normal reproduction and reproductive disorders in horses, cattle, small ruminants, swine, llamas, and other livestock. Featuring contributions from experts in the field, each section is devoted to a different large animal species and begins with a review of the clinically relevant aspects of the reproductive anatomy and physiology of both males and females. Key topics include the evaluation of breeding soundness, pregnancy diagnosis, diagnosis and treatment of infertility, abortion, obstetrics, surgery of the reproductive tract, care of neonates, and the latest reproductive technology. Includes coverage of all large animal species. All sections provide a review of clinically pertinent reproductive physiology and anatomy of males and females of each species. Complete coverage of the most current reproductive technology, including embryo transfer, estrous synchronization, and artificial insemination. A new section on alternative farming that addresses reproduction in bison, elk, and deer. New to the equine section: stallion management, infertility, and breeding soundness evaluation. New to the bovine section: estrous cycle synchronization, reproductive biotechnology, ultrasonographic determination of fetal gender, heifer development, and diagnosis of abortion. New to the porcine section: artificial insemination, boar/stud management, diseases of postpartum period, and infectious disease control. New to the llama section: infectious disease and nutrition.

The science and practice of pig production has changed rapidly overrecent decades; new husbandry practices, new understandings ofgrowth, reproduction and health, new appreciations of welfare andenvironmental impact, new nutritional approaches, and modernreproductive and genetic techniques have all come into being,together with the emergence of new health challenges. Now in its third edition, this long established reference bookon the management, breeding, feeding, nutrition, health and welfareof pigs has been fully revised to provide clear and currentinformation on both the practical and scientific aspects of the pigindustry. With the help of a new panel of international experts anda senior editor, the overall structure now contains input frominternational centres across Europe and North America. This edition includes: Updated versions of existing chapters; Completely revised and new sections on: Pig meat and carcassquality, Reproduction, The maintenance of health, Nutritional valueof protein and amino acids in feed stuffs, Value of fats and oilsin pig diets, Product marketing, Environmental management,Simulation modelling; Input from international authorities; Many tables, diagrams, photographs and figures.
