Book excerpt: Animal Agriculture: Sustainability, Challenges and Innovations discusses the land-based production of high-quality protein by livestock and poultry and how it plays an important role in improving human nutrition, growth and health. With exponential growth of the global population and marked rises in meat consumption per capita, demands for animal-source protein are expected to increase 72% between 2013 and 2050. This raises concerns about the sustainability and environmental impacts of animal agriculture. An attractive solution to meeting increasing needs for animal products and mitigating undesirable effects of agricultural practices is to enhance the efficiency of animal growth, reproduction, and lactation. Currently, there is no resource that offers specific knowledge of both animal science and technology, including biotechnology for the sustainability of animal agriculture for the expanding global demand of food in the face of diminishing resources. This book fills that gap, giving readers all the necessary information on important issues facing modern animal agriculture, namely its sustainability, challenges and innovative solutions. - Integrates new knowledge in animal breeding, biotechnology, nutrition, reproduction and management - Addresses the urgent issue of sustainability in modern animal agriculture - Provides practical solutions on how to solve the current and future problems that face animal agriculture worldwide

This book was released on 2018-01-24 with total page 509 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agroforestry systems (AFS) are becoming increasingly relevant worldwide as society has come to recognize their multiple roles and services: biodiversity conservation, carbon sequestration, adaptation and mitigation of climate change, restoration of degraded ecosystems, and tools for rural development. This book summarizes advances in agroforestry research and practice and raises questions as to the effectiveness of AFS to solve the development and environmental challenges the world presents us today. Currently AFS are considered to be a land use that can achieve a compromise among productive and environmental functions. Apparently, AFS can play a significant role in rural development even in the most challenging socioeconomic and ecological conditions, but still there is a lot of work to do to reach these goals. Considerable funding is spent in projects directed to enhancing productivity and sustainability of smallholders forestry and agroforestry practices. These projects and programs face many questions and challenges related to the integration of traditional knowledge to promote the most suitable systems for each situation; access to markets for AFS products, and scaling up of successful AFS. These complex questions need innovative approaches from varying perspectives and knowledge bases. This book gathers fresh and novel contributions from a set of Yale University researchers and associates who intend to provide alternative and sometimes departing insights into these pressing questions. The book focuses on the functions that AFS can provide when well designed and implemented: their role in rural development as they can improve food security and sovereignty and contribute to provision of energy needs to the smallholders; and their environmental functions: contribution to biodiversity conservation, to increased connectivity of fragmented landscapes, and adaptation and mitigation of climate change. The chapters present conceptual aspects and case studies ranging from traditional to more modern approaches, from tropical as well as from temperate regions of the world, with examples of the AFS functions mentioned above.

Book excerpt: The trade in live and dead animals and animal parts is a significant aspect of the global economy, but economic considerations are inevitably at odds with optimal animal welfare. Providing a snapshot of the current situation, this book discusses the background to modern international trade, welfare, and the environmental, economic and cultural issues. Covering farm, zoo and sport animals as well as the pet industry, the author draws together the competing interests and issues involved. Critically examining the overall ethics of the current situation and future of animal trade, he considers it within the context of food security, climate change, cultural sensitivities and consumer opinion.

Download or read book Fodder Crops and Amenity Grasses written by Beat Boller and published by Springer Science & Business Media. This book was released on 2010-01-14 with total page 527 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grassland farming in Europe was already established during the settlement of the rst farmers together with their domesticated animals after the last ice age. Since then, grassland provides the forage basis to feed ruminant animals for the p- duction of meat and milk. Depending on the ecological conditions and intensity of usage, various plant communities with different species developed, displaying a rich biodiversity. With the introduction of improved crop rotations at the end of the 16th century, grasses and legumes were also grown to an important extent as forage crops on arable land. In the last decades the importance of amenity grasses increased markedly, due to the demand of the society for new usages like landscape protection. Around 1900 interested farmers and academics identi ed the need for gra- land improvement through systematic selection and seed production. This marks the beginning of breeding and research in companies but also at universities and specialized research institutes. Plant collection started with many of the species that are still of importance today. The collected materials were grouped according to the intended use and some type of phenotypic selection was applied. Seed mul- plication of such populations was performed in pure stands and the harvested seed was marketed. Although the vegetative biomass and its quality are of utmost imp- tance in forage crop breeding, it is the seed yield potential which determines the commercial success of a new variety.

Download or read book Nutrition and the Welfare of Farm Animals written by Clive J. C. Phillips and published by Springer. This book was released on 2016-05-12 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the importance of good nutrition in ensuring an adequate standard of welfare for farm animals. It is often not realized that farm animals can suffer when they are fed unsuitable diets, which may be because these diets are more economic or the farmer does not know how to rectify poor nutrition. This book reveals how to recognize and deal with feeding problems in farm animals, when the animal’s behaviour is indicating a deficiency, through oral stereotypies for example. Feeding livestock in emergency situations can present special challenges, and the availability of clean and potable water, one of the essential components of life, can also be an unrecognized problem for many farm animals. Feeding farm animals effectively is rarely recognized for the major welfare issue that it is. We may assume that animals in intensive husbandry conditions have adequate feed, yet it is often too concentrated and designed primarily to immediately maximize production from the animals, in the form of growth, milk yield or reproduction. In extensive rangeland conditions adequate feed supply also cannot be assured, potentially leading to undernutrition with serious consequences for the health and even survival of livestock. This book will provide a much-needed review of the relationships between nutrition and the welfare of farm animals.

Available in PDF, EPUB and Kindle. Book excerpt: The understanding and management of land resources used by grazing animals are of major importance to ecologists and agricultural and environmental scientists. This book fills a major gap in the market by synthesising a range of perspectives on grazing systems, drawn from plant science, animal science and ecology. It outlines the principles of herbage growth and competition; of animal nutrition and grazing behavior; and of the interactions of plant and animal factors that are central to an understanding of grazing systems. Chapters on the management of grazing systems cover both intensive and extensive systems (including rangelands) from all major agroecological zones of the world. The book is written by leading authorities from the USA, UK, Australia, New Zealand, South Africa, Israel and France. It represents a major contribution to the literature for advanced students and research workers concerned with plant science (especially grasslands), animal science (especially ruminants), and natural and agricultural ecosystems.

Download or read book Plant Genetic Manipulation for Crop Protection written by A. M. R. Gatehouse and published by Oxford University Press, USA. This book was released on 1992 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most estimates of the total loss of worldwide agricultural production to pests, pathogens and weeds suggest figures of between 20 and 40 percent. A major goal therefore in current plant biotechnology is the modification of plant genomes to produce crops with enhanced resistance to pests, pathogens and herbicides. This will permit crop protection with reduced levels of application of chemical insecticides and fungicides, and the more selective use of herbicides. This book reviews our current knowledge of this rapidly advancing field and will be of great interest to plant biotechnologists and genetic engineers, as well as workers in plant pathology or agricultural entomology wishing to keep abreast of the subject.
