James Drayson has spent a lifetime researching and teaching about cattle breeding and fertility, with 35 years of experience in measuring bulls from a fertility standpoint. He followed 1,500 bulls from birth to death and recorded findings that are unequaled by any other researcher. Herd Bull Fertility will teach you how to recognize whether a bull is fertile even before the semen test. This manual, generously illustrated with photographs and diagrams, is a must for the cattle grower choosing a bull for his breeding program.

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.

This book represents the combined experience and wisdom of two leaders in sustainable cattle production. Gearld Fry offers a lifetime of practical experience seasoned by study and observation. Charles Walters draws on his own observations as well as interviews with thousands of eco-farmers and consultants over the past four decades. The result is an insightful book that is practical in the extreme, yet eminently readable. In this book you will learn: how to "read" an animal, what linear measurement is, why linear measurement selects ideal breeding stock, the nuances of bull fertility, the strengths of classic cattle breeds, the role of pastures, the mineral diets's role in health.

Cattle play a fundamental role in animal agriculture throughout the world. They not only provide us with a vital food source, but they also provide us with fertilizer and fuel. Keeping reproduction levels at an optimum level is therefore essential, but this is often a complicated process, especially with modern, high yielding cows. Written in a practical and user-friendly style, this book aims to help the reader understand cattle reproduction by explaining the underlying physiology of the reproductive process and the role and importance of pharmacology and technology, and showing how management techniques can improve reproductive efficiency. This edition includes: Recent research findings on the physiology of the oestrous cycle and its control; New techniques for monitoring and manipulating reproduction, including pregnancy diagnosis and embryo transfer; Advice on identifying common infertility problems and how to prevent and treat them. Reproduction Cattle 3e is essential reading for veterinary and agricultural students, as well as veterinarians and farmers involved in cattle reproduction.

Factors Affecting Calf Crop summarizes the latest information available from leading cattle physiologists and geneticists regarding factors known to influence the production of live calves at weaning. You get practical information on management techniques for improving reproduction efficiency in the herd. You'll also learn about the functioning of the reproductive system and how this may affect reproductive processes in the cow herd. Managers will benefit from a clearer understanding of the factors known to limit efficient reproduction, while veterinarians and other professionals who advise cattlemen will appreciate the substantial reference material and color photographs for defining cow condition scores. Color photographs are also used to illustrate the discussions of testicular thermographies and their applications. Other chapters in the book cover developments in improving reproductive performance of the replacement heifer, the brood cow, and the bull. Topics on reproduction include physiology/endocrinology, the use of growth promotants, genetics and physiological and economic considerations in selecting the age to breed heifers, heritability of fertility, length of the breeding season, prepartum and postpartum nutrition, nursing by the calf, cloning of embryos, and much more.

Thoroughly updated to reflect recent changes in the industry, Bovine Medicine, 3rd Edition, offers practicing large animal veterinarians and veterinary students a comprehensive reference to core aspects of contemporary cattle health and husbandry. New edition of a classic text, featuring thoroughly rewritten text, with coverage shifted to the core aspects of everyday cattle practice Includes new focus on both applied skills and application of knowledge, along with many more full-colour illustrations than in previous editions Represents a toolkit of skills that will support the delivery of contemporary cattle practice Presents a seamless integration of information on husbandry, nutrition, and disease Written by a wide range of experts from around the world

Deals with feed evaluation systems, the nutrient requirements of ruminant livestock and the feeding value of a wide range of feedstuffs. This book lists about 800 typical forages, 65 crop residues and 120 concentrate and by-product feeds. It is suitable for teachers, specialist scientists and industrialists.

​​​​​​​​​​​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.

Dairy cow herd health is an important and universal topic in large animal veterinary practice and farming, covering both preventive medicine and health promotion. With the move towards large scale farming, the health of the herd is important as an economic unit and to promote the health of the individuals within it. This book will focus on diseases within herds, herd husbandry practices, youngstock management and environmental issues. Major diseases and conditions will be covered such as mastitis, lameness, nutrition, metabolic and common infectious diseases from a herd health perspective.
