Book Description
This book provides a broad perspective on understanding bovine fertility, focusing on the classification and interpretation of bovine sperm defects. Building upon the success of its first edition published in 1989, this new edition has been significantly updated and expanded to reflect developments over the past three decades. The chapters cover topics such as the normal and abnormal development of bovine sperm, the mechanisms behind sperm defects, and the impact of these defects on fertility. Special attention is drawn at advances in genomic research and the use of sperm quality biomarkers and genetic screening tests in the assessment of bull fertility. In addition to this, the work explores critical periods for sexual development in bulls, such as early gestation and pre-weaning. This monograph is intended for researchers and students in the field of animal reproduction, veterinarians, and animal scientists. It provides a deep understanding of bovine fertility, a topic that is crucial for anyone working in livestock production or related fields. The knowledge gained from this book will be beneficial to those seeking to improve livestock productivity and thus contribute to global food security.

Book Description
A combination of in vitro fertilization (IVF) and sperm function tests were used to determine the fertilizing characteristics of bovine sperm with abnormal morphology. Bovine sperm affected with the pyriform defect had a reduced ability to bind to and penetrate zonae pellucidae and although those penetrating oocytes were involved in the fertilization process, the resulting zygotes appeared to have a reduced ability to initiate cleavage. Bovine sperm with the knobbed acrosome defect had a reduced ability to bind to and penetrate the zona pellucida. Knobbed sperm had impaired sperm plasma membrane function which predisposed them to spontaneous acrosome reaction on incubation after thawing, reducing oocyte interaction. The post-zona penetration fertilizing characteristics of normal sperm associated with knobbed sperm also appeared to be impaired. Bovine sperm with multiple nuclear vacuoles had a reduced ability to bind to and penetrate the zona pellucida of bovine oocytes. However, those gaining access to the ooplasm participated normally in fertilization. A proportion of sperm with proximal droplets failed to swim through the sodium hyaluronate swim-up medium and sperm with proximal droplets failed to bind with the zona pellucida of oocytes. Apparently normal sperm co-existing in the semen along with proximal droplets were also functionally deficient, resulting in reduced zonae binding, and those oocytes that were fertilized did not develop beyond the cleavage stage of development. In summary, morphologically abnormal sperm failed during the various steps of the fertilization process depending on the nature of abnormality. However, knobbed sperm, pyriform-shaped sperm, sperm with multiple nuclear vacuoles and sperm with proximal cytoplasmic droplets appeared to have similar functional deficiencies suggesting that abnormal morphology may be a marker of accompanying functional deficiencies. The normal sperm coexisting in the semen along with high proportions of abnormal.

Book Description
A practical guide to interpreting sperm morphology of domestic animals Sperm Morphology of Domestic Animals is a concise, clinically-oriented resource for discovering any impairment to fertility caused by sperm anomalies in domesticated animals. As a bench-side reference, the book examines common sperm defects, their causes, and their prognosis for fertility. An easy-to-use reference, it is organized according to the placement of the deformity in the sperm to increase the speed of consultation, and to help with diagnosing fertility issues. Focusing particularly on the bull, stud horse, boar, ram, buck, and dog, it contains hundreds of high-quality color images accompanied by brief descriptions for additional diagnostic help. Readers will find: An easy-to-use reference work that is suitable for use next to the microscope Organization according to location of abnormality Hundreds if high-quality color images for easy comparison Brief descriptions accompanying each photo, for additional diagnostic help An ideal resource for veterinarians, andrologists, and veterinary students, Sperm Morphology of Domestic Animals fills a gap in current reproductive medicine resources with detailed information that is easy to consult.

Book Description
Bovine Reproduction is a comprehensive, current reference providing information on all aspects of reproduction in the bull and cow. Offering fundamental knowledge on evaluating and restoring fertility in the bovine patient, the book also places information in the context of herd health where appropriate for a truly global view of bovine theriogenology. Printed in full color throughout, the book includes 83 chapters and more than 550 images, making it the most exhaustive reference available on this topic. Each section covers anatomy and physiology, breeding management, and reproductive surgery, as well as obstetrics and pregnancy wastage in the cow. Bovine Reproduction is a welcome resource for bovine practitioners, theriogenologists, and animal scientists, as well as veterinary students and residents with an interest in the cow.
