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 35-chapter book is based on several oral and poster presentations including both invited and contributory chapters. The book is thematically based on four pillars of sustainability, with focus on sub-Saharan Africa (SSA): Environment, Economic, Social and Institutional. The environmental sustainability, which determines economic and social/institutional sustainability, refers to the rate of use of natural resources (soil, water, landscape, vegetation) which can be continued indefinitely without degrading their quality, productivity and ecosystem services for different ecoregions of SSA. This book will help achieve the Sustainable Development Goals of the U.N. in SSA. Therefore, the book is of interest to agriculturalists, economists, social scientists, policy makers, extension agents, and development/bilateral organizations. Basic principles explained in the book can be pertinent to all development organizations.
Although it is recognised that Thomas Robert Malthus was wrong when he posited a contradiction between population increase and agricultural growth, there are increasing signs that he could be proved right in the future. Perhaps Malthus was too late and too early in his prediction? He was too late, because he did not foresee the shift from land-based resources to fossil fuels, outing an end to the limits of agricultural growth, at least temporarily; and he was too early to witness that fossil fuels would come up against their own limits in terms of supply as well as in terms of global warming. This study deals with land-based resources and the role they play in the global socio-ecological metabolic regime, both now and in the future. In particular, the controversial use of agrofuels as a solution to coming scarcity is subjected to close scrutiny.
Bovine Medicine provides practical and comprehensive information oncattle disease and production and is a key reference for all largeanimal vets. Since the first edition was published in 1991 therehave been significant improvements in disease control andmanagement of cattle. Almost all parts of the book have beenupdated and completely rewritten. There are new chapters onsurgery, embryo transfer, artificial insemination, ethno-veterinarymedicine and biosecurity, and a new consolidating chapter on theinteraction between the animal, environment, management anddisease. The previous edition has sold all over the world, and as aresult of this a greater emphasis has been placed on conditions andtheir treatment in areas other than temperate regions. A newsection entitled "Global Variation in Cattle Practice" has beenincluded with contributors discussing bovine medicine practice intheir part of the world. All in all this is an outstanding resource for any practisingvet and an excellent reference for veterinary students.
