The Effects Of Various Factors On Repeat Breeding In Dairy Cattle

Veterinary medicine is advancing at a very rapid pace, particularly given the breadth of the discipline. This book examines new developments covering a wide range of issues from health and welfare in livestock, pets, and wild animals to public health supervision and biomedical research. As well as containing reviews offering fresh insight into specific issues, this book includes a selection of scientific articles which help to chart the advance of this science. The book is divided into several sections. The opening chapters cover the veterinary profession and veterinary science in general, while later chapters look at specific aspects of applied veterinary medicine in pets and in livestock. Finally, research papers are grouped by specialisms with a view to exploring progress in areas such as organ transplantation, therapeutic use of natural substances, and the use of new diagnostic techniques for disease control. This book was produced during World Veterinary Year 2011, which marked the 250th anniversary of the veterinary profession. It provides a fittingly concise and enjoyable overview of the whole science of veterinary medicine.

Because of the lockdown from the beginning of 2020, many educated young people in the age group of 25-35 has been moved to their hometown and villages. This has compelled them to work online from home and thinking to explore the possibility of animal keeping. This includes fish, goats, buffalo, Desi cows and the exotic cows. All of these the exotic cow seems to be more promising because it gives milk every day and it is a good source of income. Because of the green revolution have been irrigated area of western U.P., Haryana, Punjab, Gujarat and MP. With the introduction of the high yielding exotic breeds of North American and European origin it is very much possible to produce 100 litres of milk from 10-15 animals. These animals survive very well on the agriculture by-products like wheat straw and paddy straw has meant the production of milk without land. The keeping of the exotic cows like Jersey and Holstein has become a leading business to the property dealer, hotel owners and the educational institutions. With the availability of inputs like disease control, reproduction, nutrition, management, and environmentally controlled housing has meant the keeping of dairy animal as an investment. In the recent time the availability of the frozen sexed semen producing only the female calves has revolutionized the dairy industry. The rate of replacement of herd is has doubled. Mostly the cow and buffalo are purchased from Punjab, Haryana and western UP. The cost of transportation from these area is very high. It is necessary for farmer to produce cows or buffalos along with the production of milk. The biggest constrain in this venture is repeat breeding. The failure of conception after repeated artificial insemination service, this is too much discouraging and this involves factors like quality of semen, trained personals, reproductive technology, nutrition, control of blood parasites, internal parasites and external parasite, and pathological conditions of the uterus etc. In this book from my experience of last 50 years in teaching the cow reproduction and treating the animals for repeat breeding I have sum up the different causes of failure. Hope these suggestions given in this book will help the dairy farmers to know some of the reasons for the failure of conception resulting in repeat breeding. Your suggestions and criticism in improving this book will be appreciated.

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.

This textbook provides a detailed view of the different ways in which reproduction in cattle, sheep, pigs and horses can be controlled and manipulated. It is primarily of interest to students of animal science and veterinary medicine, but will also be of use to those who are concerned with the practical aspects of reproduction control, whether in an advisory capacity or in applying techniques on the farm itself. A major objective of the book is to draw attention to information which may be used directly to increase the efficiency of the livestock industry.

This book provides updated information on the current concepts in bovine reproduction. It describes the complex issues associated with fertility and infertility in bovines and suggests strategies for achieving high reproductive efficiency. It discusses topics related to the fertility trend in bovines, estrus detection, controlled breeding, postpartum uterine health, uterine infections, and its therapeutic management. The essential roles of metabolic hormones on gonadal functions and fertility are also covered. Additionally, the book presents new insights in maternal recognition of pregnancy in bovines and suggest nutritional strategies to improve reproductive efficiency. The chapters on male fertility provide current information on semen cryopreservation, sperm quality assessment and measures to improve sperm fertility. A special chapter on intricacies in buffalo semen cryopreservation and measures to improve the quality of cryopreserved sperm is also included in this book. Lastly, the book introduces the immunobiological roles of anti-microbial peptides during sperm transport in reproductive tract and epigenetic bearing on fertility. This book is an invaluable resource for veterinary scientists, students and practitioners to understand the current developments in bovine reproduction for improving reproductive efficiency.
