Available in PDF, EPUB and Kindle. Book excerpt: Chickens are now the most scientifically engineered of livestock. How have the methods used by geneticists differed from those employed by domestic breeders over time? Art and Science in Breeding details the relationship between farm practices and agricultural genetics in poultry breeding from 1850 to 1960. Margaret E. Derry traces the history and organization of chicken breeding in North America, from craft approaches and breeding as an ‘art,’ to the conflicts that had emerged between traditional and scientific methods by the 1940s. Derry assesses links between the 'scientific' revolution of chicken farming and the development of corporate breeding as a modern, international industry. Using poultry as a case study for the wider narrative of agricultural genetics, Art and Science in Breeding adds considerable knowledge to a rapidly growing field of inquiry.

Download or read book Global Livestock Production Systems written by Timothy P. Robinson and published by Food & Agriculture Organization of the UN (FAO). This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Informed livestock sector policy development and priority setting is heavily dependent on a good understanding of livestock production systems. In a collaborative effort between the Food and Agriculture Organization and the International Livestock Research Institute, stock has been taken of where we have come from in agricultural systems classification and mapping; the current state of the art; and the directions in which research and data collection efforts need to take in the future. The book also addresses issues relating to the intensity and scale of production, moving from what is done to how it is done. The intensification of production is an area of particular importance, for it is in the intensive systems that changes are occurring most rapidly and where most information is needed on the implications that intensification of production may have for livelihoods, poverty alleviation, animal diseases, public health and environmental outcomes. A series of case studies is provided, linking livestock production systems to rural livelihoods and poverty and examples of the application of livestock production system maps are drawn from livestock production, now and in the future; livestock's impact on the global environment; animal and public health; and livestock and livelihoods. This book provides a formal reference to Version 5 of the global livestock production systems map, and to revised estimates of the numbers of rural poor livestock keepers, by country and livestock production system.

Download or read book Before Dinner written by M. Korthals and published by Springer Science & Business Media. This book was released on 2008-11-09 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an extensive, original and systematic treatment of many important philosophical and ethical aspects of food (consumption and production). May we eat just anything? Can we do everything with animals, even genetic modification? If not, how can we regulate those processes so that they lead to optimum animal welfare while at the same time producing optimum taste? The production of food also causes environmental pollution – does the fight against hunger have priority over the care of the environment? The care of the environment, animal welfare, and the quality of food should be in a certain harmony, but that is far from granted and hardly easy to achieve. These factors are often in conflict with each other, and a balance will thus need to be searched for. Other factors to take into consideration are the issue of global famine, the care for a farming class that is able to keep its head above water in a decent way, and a fair trade system that does not throw up unnecessary barriers for newcomers or small market participants and that promotes good nutrition. Famine continues to be a widespread phenomenon that violates human rights, causing nearly a billion people to suffer from hunger or malnutrition. At the same time, deliberate hunger, abundance, and obesity are prevalent in the Western world. Both issues refer to the social and cultural aspects of food. Scientific and technological developments like genetic modification and functional food also play an increasingly important role; almost every bite that we take is determined by scientific developments. An extra difficulty is that scientific information is often contradictory, or that it relies on statistical probabilities that are difficult to translate into everyday certitudes. All of these factors deserve attention, but it is the mix that is most important. In the land of food, ‘either or’ does not exist, only ‘both and’. The adequate measure of ‘both and’ serves as the starting point for this philosophical reflection. Before Dinner is a must-read for all people interested in contemporary ethical issues of food, such as university students and researchers of food, agricultural and life sciences, as well as policymakers in these fields, such as members of professional organisations focusing on food and agriculture (f.e., EURSAFE (European Society for Agriculture and Food Ethics), the Agriculture, Food and Human Values Society (USA), and European Federation of Biotechnology).

Download or read book Biogenetic Paradoxes of the Nation written by Sakari Tamminen and published by Duke University Press. This book was released on 2019-11-22 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1992, the Convention on Biological Diversity (CBD), signed by over 160 countries and hailed as the key symbol of a common vision for saving Earth's biodiversity, set forth three primary mandates: preserving biodiversity, using biodiversity components sustainably, and enabling economic benefit-sharing. The CBD—which gave signatory countries the ability to claim sovereignty over nonhuman genetic resources native to each nation—defined biodiversity through a politics of nationhood in ways that commodified genetic resources. In Biogenetic Paradoxes of the Nation Sakari Tamminen traces the ways in which the CBD's seemingly compatible yet ultimately paradox-ridden aims became manifest in efforts to create, conserve, and capitalize on distinct animal and plant species. In using Finland as a case study with which to understand the worldwide efforts to convert species into manifestations of national identity, Tamminen shows how the CBD's policies contribute less to biodiversity conservation than to smoothing the way for frictionless operation of biotechnologically assisted circuits of the global bioeconomy. Tamminen demonstrates how an intimate look at the high-level politics and technical processes of defining national genetic resources powerfully illuminates the limits of anthropocentric biopolitical theory.

This book was released on 2010-09-11 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Future of Life: A Unified Theory of Evolution represents the first comprehensive formulation of the hypothesis that evolution is the unifying force underlying the dynamics of all processes in the universe- both organic and inorganic. In essence by combining information, decision, network and quantum theory, it is demonstrated that an overarching evolutionry process shapes the spectrum of life and all phenomena in the universe, beyond Darwin's original biological theory.
