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.

With increasing pressure on resources, the looming spectre of climate change and growing anxiety among eaters, ecology and food are at the heart of the political debates surrounding agriculture and diet. This unique contribution unravels agri-environmental issues at different spatial levels, from local to global, documenting the major shifts in agriculture from a long-term perspective. The book begins by exploring the changes in the industrialisation and socialisation of agriculture over time, through the lens of institutional economics including The French Regulation School and Conventions Theory. Building on Polanyi’s ‘Great Transformation’, the chapters in this volume analyse long-term and contemporary changes in agriculture and food systems that have occurred throughout the last few centuries. Key chapters focus on the historical changes in provisioning and the social relations of production, consumption, and regulation of food in different socio-political contexts. The future of agriculture is addressed through an analysis of controversial contemporary political claims and their engagement with strategies that aim to improve the sustainability of agriculture and food consumption. To shed light on ongoing changes and the future of food, this book asks important environmental and social questions and analyses how industrial agriculture has played out in various contexts. It is recommended supplementary reading for postgraduates and researchers in agricultural studies, food studies, food policy, the agri-food political economy and political and economic geography.

This publication provides an update on the current status of gene maps in different livestock and pet/companion animal species. The findings summarized in species specific commentaries and original articles testify the rapid advances made in the field of animal genomics. Of significant interest is the fact that current investigations are providing headways for two important and exciting research fronts: targeted high-resolution mapping leading to the application of genomic information in addressing questions of economic and biological significance in animals, and the initiation of whole genome sequencing projects for some of the animal species. Like in humans and mice, this will set the stage for a new level of research and real time complex analysis of the genomes of these species. Animal Genomics signifies the beginning of a new era in this field and celebrates the achievements of the past 20 years of genomics research. It will be of special interest to researchers involved in genome analysis - both gross chromosomal as well as molecular - in various animal species, and to comparative and evolutionary geneticists.
