View Rights PortalWatkins Media Ltd. consists of 4 imprints - Watkins (self-help, personal development and mind, body, spirit), Nourish (healthy living and cookery), Angry Robot (science fiction and fantasy) and Repeater (Radical Politics, Fiction and Philosophy). The story of Watkins Publishing dates back to March 1893, when John M. Watkins, a scholar of esotericism, overheard his friend and teacher Madame Blavatsky lamenting the fact that there was nowhere in London to buy books on mysticism, occultism or metaphysics. At that moment Watkins was born, soon to become the home of many of the leading lights of spiritual literature, including Carl Jung, Rudolf Steiner, Alice Bailey and Chögyam Trungpa. Today our passion for vigorous questioning is still resolute, our books have continued to reflect the development of spiritual thinking and new science over the past 120 years. We remain at the cutting edge, committed to publishing books that change lives.
View Rights PortalThis book is concerned with protein metabolism at the physiological, not the molecular level and particularly with studies on human beings. Protein turnover is a vital function, no less important than oxygen turnover, because of this over the last 20 years there has been an increase in the research on protein turnover in man, with parallel work on farm animals. Methods that have been used for measuring whole body protein turnover in man, the underlying problems and assumptions and the problems that have been encountered are discussed in this comprehensive book.
This 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.

The Encyclopedia of Animal Nutrition covers animal nutrition across a wide range of disciplines, including physiology, biochemistry, veterinary medicine and feed technology. Through approximately 3000 entries ranging from short definitions to more discursive articles, it discusses and illuminates on all aspects of this important topic. The book: - Covers every type of animal managed in developing and developed countries, from livestock and companion animals to those commonly found in laboratories and zoos; - Expands usual definitions of 'livestock' to include farmed invertebrates such as honey bees and prawns, and animals of localised significance such as yaks, snakes, crocodiles, and asses; - Addresses important societal topics in relation to nutrition, including welfare, environmental pollution, disease, resource use, and animal product quality. Written by a global team of contributors and expert section editors, this book is an important resource for researchers, students and advisers of animal nutrition, as well as anyone interested in agriculture, veterinary science, zoology, physiology, equine science, and animal behaviour.
The use of biological control agents has been increasing worldwide and there are now many companies mass-producing such organisms, particularly for the control of insect pests. However, there is a great need for quality control in the production and use of these natural enemies, which include insect parasitoids and predators, fungi and viruses. This book has been written by leading scientists from Europe and North America to provide both background theory and practical guidance on this subject.
Many advances have recently taken place in dairy science and this book provides timely reviews of a number of such key topics. The subject matter is divided into five sections, covering: nutrition and physiology; breeding and reproduction; health maintenance and control; milking and milk technology; and the environment and ethics. All chapters have been specially commissioned for this volume from international authorities from Europe, North America and Africa. The book represents an important update of the literature for research workers, lecturers, advisers and advanced students in many areas of animal science as well as veterinarians concerned with bovine medicine.
This introductory level textbook covers the welfare and environmental implications of producing cattle as well as traditional subjects such as nutrition, reproduction and housing. Its broad, international coverage includes feedlot systems, transport, subsistence farming systems and the contribution of cattle production systems to land, air and water pollution. It is an invaluable resource for undergraduate students of animal science, veterinary medicine and agriculture, as well as diploma and certificate courses and industry personnel. Praise for the first edition: "The book is to be recommended to university students of animal science, agriculture and veterinary medicine and it represents a valuable source of information for anyone interested in cattle farming" - Reproduction in Domestic Animals Principles of Cattle Production is ideal for use in teaching at diploma and degree level. - Animal Reproduction Science "The overview of the industry and its place in society now, and in the future, is extremely well written and for those of us involved on a daily basis is well worth reading." - The Veterinary Journal "It emphasizes relevant aspects of disease, environment, animal welfare and sustainability that deserve full consideration in today's climate of opinion" - Journal of Animal Breeding and Genetics
This book is a much-expanded and updated edition of a previous volume, published in 1996 as "No-tillage Seeding: Science and Practice". The base objective remains to describe, in lay terms, a range of international experiments designed to examine the causes of successes and failures in no-tillage. The book summarizes the advantages and disadvantages of no tillage. It highlights the pros and cons of a range of features and options, without promoting any particular product.Topics added or covered in more detail in the second edition include:* soil carbon and how its retention or sequestration interacts with tillage and no-tillage* controlled traffic farming as an adjunct to no-tillage* comparison of the performance of generic no-tillage opener designs* the role of banding fertilizer in no-tillage* the economics of no-tillage* small-scale equipment used by poorer farmers* forage cropping by no-tillage* a method for risk assessment of different levels of machine sophistication
