October 2014 CGRFA/WG-AnGR-8/14/Inf.2 – Part 1 & 2 E COMMISSION ON GENETIC RESOURCES FOR FOOD AND AGRICULTURE Item 3 of the Provisional Agenda INTERGOVERNMENTAL TECHNICAL WORKING GROUP ON ANIMAL GENETIC RESOURCES FOR FOOD AND AGRICULTURE Eighth Session Rome, 26-28 November 2014 DRAFT SECOND REPORT ON THE STATE OF THE WORLD'S ANIMAL GENETIC RESOURCES FOR FOOD AND AGRICULTURE Part 1 & 2 Status of preparation All parts of The second report on the world's animal genetic resources for food and agriculture (Second Report) have been drafted. However, Part 4 – State of the art in the management of animal genetic resources – is at an early stage of drafting and will thus not be made available to the Working Group. While a number of sections of the Second Report have been reviewed by FAO and external experts, these sections still need to be revised based on the comments received. Review of the remaining sections remains to be arranged. The whole report needs to be further edited to ensure internal consistency and improve readability. The acknowledgements, preface, executive summary and list of abbreviations and acronyms still need to be prepared. It is foreseen that a full draft of the Second Report will be ready in March 2015. This document is printed in limited numbers to minimize the environmental impact of FAO's processes and contribute to climate neutrality. Delegates and observers are kindly requested to bring their copies to meetings and to avoid asking for additional copies. Documents for this meeting are available on the Internet at http://www.fao.org/Ag/AGAInfo/programmes/en/genetics/angrvent.html Draft Second Report on the State of the World’s Animal Genetic Resources for Food and Agriculture NOT FOR CITATION COMMISSION ON GENETIC RESOURCES FOR FOOD AND AGRICULTURE FOOD AND AGRICULTURE ORGANIZATION OF THE UNITED NATIONS Rome, 2014 The designations employed and the presentation of material in this information product are not warranted to be error free and do not imply the expression of any opinion whatsoever on the part of FAO concerning the legal status of any country, territory, city or area or of its authorities, or concerning the delimitation of its frontiers or boundaries.

Part 1 THE STATE OF LIVESTOCK DIVERSITY iii Introduction Part 1 of the report begins by describing the advances in research on the origin of the diversity of today’s animal genetic resources for food and agriculture – the domestication and history of livestock species. This is followed by a description of the current status and trends of animal genetic resources diversity and the extent to which this diversity is threatened by genetic erosion. The next section describes patterns of international exchange of animal genetic resources. The roles and values of AnGR, and their direct and indirect contributions to livelihoods and economic output are then outlined. The importance of genetic resistance and tolerance to disease is then discussed followed by threats to the world’s animal genetic resources diversity. In the final section of Part 1, livestock diversity is discussed in relation to human nutrition. All sections highlight changes since the first report on The State of the World’s Animal Genetic Resources for Food and Agriculture (first SoW- AnGR) was drafted. AnGR are here taken to include those animal species that are used, or may be used, for food production and agriculture1, and the populations within each. Distinct populations within species are usually referred to as breeds. FAO (19992) defines breed as: either a subspecific group of domestic livestock with definable and identifiable external characteristics that enable it to be separated by visual appraisal from other similarly defined groups within the same species or a group for which geographical and/or cultural separation from phenotypically similar groups has led to acceptance of its separate identity. The broad definition of the term “breed” is a reflection of the difficulties involved in establishing a strict definition of the term. Further information on the development of the breed concept is provided in the first SoW-AnGR (FAO, 20073). 1 Fish are excluded as management requirements and breeding techniques are very different. 2 FAO. 1999.
