View Rights PortalThis report reviews the energy and protein requirement systems for dairy cows currently used in Britain and presents a new approach, along with the outline of a model for its implementation. Current systems give little consideration to the responses of the animal to changes in the nutrient supply, or to interactions between dietary constituents in their effects on digestion and metabolism. Neither do they predict any effect on the partition of nutrient use between milk and body, or changes in the yields of milk fat, protein and lactose, which determine the commercial value of the milk. Therefore the systems, although not inaccurate, lack relevance to the current needs of UK milk producers. Models which embody concepts of nutrient supply and utilization are reviewed and their development as viable alternatives is considered. It is concluded that a new diet formulation system for dairy cows should aim to predict voluntary feed intake, the partition of nutrient use between milk production and tissue deposition, and the short and long-term of effects of nutrition on fat, protein and lactose yields. The physical and biological characteristics of the cow must also be recognized and incorporated into any model for response prediction. The report is also published in Nutrition Abstracts and Reviews - Series B: Livestock Feeds and Feeding. It is an authoritative review for advanced students, research workers and advisors in animal nutrition and in dairy science and technology.
Tourism based on natural environments is a huge international industry and this industry needs access to land with scenery, native plants and wildlife. In turn, land managers need money to maintain their land and its natural resources. This book looks at the economic, social and environmental consequences of nature-based tourism. It discusses the importance of links and partnerships, as well as the conflicts,between commercial tourism interests and land management agencies. Born from the Fenner conference on Nature Tourism and the Environment, held in Canberra, Australia, 2001, the book includes selected proceedings which have been refereed and substantially revised.
Ecotourism is the result of increasing interest amongst consumers in developed countries in exploring the natural world as an alternative to more conventional holidays, along with a desire to reduce the environmental and cultural impact of their activities. It is, therefore, a relatively new sector of the tourism industry. This book is unique in defining, describing and analysing ecotourism in the less developed countries and its effects, in all parts of the world. The first three chapters set the broader industry context and geographical scope of the book. This is followed by country case studies on Costa Rica, Kenya, Nepal and Thailand and a chapter on the Caribbean and South Pacific. In the final chapter, the common themes and patterns which emerge are discussed with regard to strategies for future developments. This book is essential reading for lecturers, advanced students and researchers in tourism and for those actively involved in ecotourism in less developed countries. It will also be valuable to other tourism industry staff, geographers, development economists and government and regional policy makers.
Dramatic increases in food prices, as witnessed on a global scale in recent years, threaten the food security of hundreds of millions of the rural poor in Sub-Saharan Africa alone. This book focuses on recent food and financial crises as they have affected Africa, illustrating the problems using country case studies, that cover their origins, effects on agriculture and rural poverty, their underlying factors and making recommendations as to how such crises could best be addressed in the future.
The need to increase food production, enhance economic growth and reduce poverty in an environmentally sustainable context is an issue of growing importance. This book addresses the linkages and tradeoffs involved in solving such key challenges.
Whilst the actual reduction of nitrogen gas (dinitrogen) to ammonia would appear to be a well defined process, many research questions concerning nitrogen fixation remain and continue to be addressed by diverse groups of scientists. This book presents the proceedings of the 13th International Congress on Nitrogen Fixation, held in Hamilton, Ontario, Canada, in July 2001. With very broad participation and a wide range of topics, it covers the most recent findings. In fifteen sections the main topics discussed include; bacterial genomics, plant genomics, development biology, signals in the soil, nodule metabolism and applied aspects of nitrogen fixation.
Welfare research has established a range of scientific indicators of stress, welfare and suffering in animals that can be applied to all aspects of improving their welfare through good housing and management, and the topic continues to grow in importance among both professionals and the public. The practical focus of this authoritative, comprehensive encyclopedia aims to promote the understanding and improvement of animals’ behaviour without compromising welfare. Under the editorial direction of Professor Daniel Mills, the UK’s first specialist in veterinary behavioural medicine, over 180 international experts have contributed a wealth of fully cross-referenced entries from concise definitions to detailed short essays on biological, practical, clinical and ethical aspects of behaviour and welfare in domestic, exotic, companion and zoo animals.

There are over 40 000 named species of mite, and if estimates for unnamed species are included, then up to 1 million may grace the planet. By comparison, there are approximately 40 000 species of vertebrates, half of them fish, alive today. Mites are predators, parasites, herbivores and detritivores. They live in the dark depths of the ocean, in the lungs of birds, on the leaves of rainforest plants, and in human clothes and bedding. They are vectors of disease, vital players in soil formation, and important agents of biological control. Despite the grand diversity of mites, these small arthropods are often overlooked, and even trained biologists can be unaware of their significance.This books aims to fill the gap in our understanding of these intriguing creatures. It surveys life cycles, feeding behaviour, reproductive biology and host-associations of mites, without requiring prior knowledge of their morphology or taxonomy. The text is richly illustrated with line drawings and photographs. Topics covered include evolution of mites and other arachnids, mites in soil and water, mites on plants and animals, sperm transfer and reproduction, and mites as models of ecological and evolutionary theories.
Tourism based on natural environments is a significant and growing international industry, and one that requires access to land with scenery, native plants and wildlife. In turn, land managers need money to maintain their land and its natural resources. This book looks at the economic, social and environmental consequences of nature-based tourism, and its effects on land managers. It discusses the importance of links and partnerships, as well as the conflicts between commercial tourism interests and land management agencies. Now in paperback, this book will be an essential resource for tourism students, as well as researchers and industry practitioners.
