The domestic pig is perceived as an animal with intelligence and character and yet, in the industrialized world, the majority of people have had little or no contact with them. Pigs are subject to a wide range of environments from the tropics to the sub-arctic, ranging from small-scale, extensive systems to large-scale intensive systems. They may spend their whole life on one farm or may be subject to long-distance transport multiple times. Not surprisingly, many aspects of their life experiences can impact their welfare.

This book brings together a team of leading pig welfare research scientists to review the natural history of the pig, the welfare of pigs at different stages of life and to indicate what the future holds in terms of pig welfare. The text is aimed at researchers and teachers working in veterinary and animal science together with those working in the pig industry and for governmental and non-governmental animal welfare organizations.

Epigenetic Mechanisms of the Cambrian Explosion provides readers with a basic biological knowledge and epigenetic explanation of the biological puzzle of the Cambrian explosion, the unprecedented rapid diversification of animals that began 542 million years ago. During an evolutionarily instant of ~10 million years, which represents only 0.3% of the time of existence of life on Earth, or less than 2% of the time of existence of metazoans, all of the 30 extant body plans, major animal groups (phyla) and several extinct groups appeared. The work helps address this phenomena and tries to answer remaining questions for evolutionary biology, epigenetics, and scientific researchers. The book recognizes and presents objective representations of alternative theories for epigenetic evolution in this period, with the author drawing on his epigenetic theory of evolution to explain the causal basis of the Cambrian explosion. Both empirical evidence and theoretical arguments are presented in support of this thought-provoking epigenetic theory.

In the spring of 1996, when numerous reports of bovine spongioform encephalopathy, popularly known as "mad cow disease," coincided with an outbreak of a similar neuropathological disease in humans, a panic spread across Britain, Europe, and subsequently to the United States. Described as "the biggest crisis the European Union ever had," the mad cow controversy raised important issues about the ways in which risks to the public heath are assessed, disseminated, and controlled. Was the "epidemic" merely a failure of management, the lessons of which could be incorporated into a new strategy for dealing with public anxiety? Was it an isolated case of poor decision-making in a highly volatile economic sector, or was it the kind of nightmare that could face any government responsible for public safety? And what role did the media play in exacerbating an already spiraling crisis?

Divided into four major sections-"Scientific/Historical Perspectives"; "Politics as Health"; "Understanding the Crisis"; and "Lessons and Possibilities" - Mad Cow Crisis assembles the perspectives of a range of experts on this strange and frightening phenomenon, with a view to helping us comprehend how and why such crises occur. Both a careful consideration of how we interpret risk and uncertainty and a step-by-step guide to managing public fear, this important book will interest anyone concerned with public health, communication, science, economics, and medicine.

The growth of the wildlife industry in South Africa can be measured by the growth in the number of wildlife ranches.
