Book Description
Now in a much-anticipated two-volume new edition, this gold-standard reference stands as the most comprehensive and authoritative text on equine reproduction. Serving theriogenologists, practitioners and breeders worldwide as a one-stop resource for the reproductive assessment and management of equine patients, Equine Reproduction, Second Edition provides detailed information on examination techniques, breeding procedures, pregnancy diagnosis and management, reproductive tract diseases and surgery, and foaling. A companion website offers hundreds of images from the book in color. For the Second Edition, the stallion, mare and foal sections have been thoroughly updated and revised to include the latest information on every subject. New topics include discussion of nutritional and behavioral factors in the broodmare and stallion, parentage testing, fetal sexing and the health and management of older foals, weanlings and yearlings. Additionally, this outstanding Second Edition features a new section on assisted reproductive techniques, including detailed information on artificial insemination, in-vitro fertilization, embryo transfer and technology.

Embryonic Mortality in Farm Animals
Author: J.M. SreenanPublisher: Springer Science & Business Media
ISBN: 9400950381
Category : Medical
Languages : en
Pages : 294
Book Description
Reproductive wastage is a major inefficiency in all livestock production with embryonic mortality accounting for a major portion of this loss. Accordingly the Commission of the European Communities encouraged the organisation of a seminar on embryonic mortality in farm animals which was held in Brussels on the 11th and 12th of December 1984. This book contains the text of the papers, discussions and final summary presented at that Seminar. As a background to the Seminar, the extent and timing of embryonic loss was described for farm animals. Particular consideration was then given to the various mechanisms and signals, both embryonic and uterine in origin, that are so far known to be involved in the establishment of pregnancy. Possible causes of embryonic death including physiological, endocrinological, genetic and immunological components were outlined and discussed. The final summary contains general conclusions from the Seminar and recommendations for future research work on this topic. J.M. Sreenan M.G.

Temperature and Environmental Effects on the Testis

Book Description
It must be considered that there is nothing more difficult to carry out, nor more doubtful of success, nor more dangerous to handle, than to initiate a new order of things. Machiavelli: The Prince (1513) These are the Proceedings of a Conference on Temperature and Environmental Factors and the Testis which took place at New York University School of Medicine, December 8th and 9th, 1989. There is good reason to believe that this was the first of its kind to address, exclusively, the implications of temperature for this highly thermosensitive organ and its precious genetic cargo. The organizers of the Conference hoped to stimulate interest in this area which, paradoxically, has a considerable literature but which has received scant attention and sometimes outright opposition from clinicians expert in male infertility. There have been studies of the relationship of temperature to reproduction starting in the mid-18th Century with observations of the relationship of water temperature to spawning of fish. There is also a vast literature on the deleterious effects of externally applied heat upon spermatogenesis but little study of the possibility that intrinsic heat may be an important etiologic factor in subfertile semen. Today, fertility research has largely ignored this in favor of research in areas which have not produced successes, in terms of live births, comparable to what can be obtained by varicocelectomy (when appropriate) or scrotal hypothermia: viz. 1. Concentration upon the endocrine aspects of testicular function and its relation to spermatogenesis.
