The Domestic Animal Diversity Information System (DAD-IS) is a multilingual (English, French and Spanish), dynamic database-driven web-based information system supporting the implementation of the Global Plan of Action for Animal Genetic Resources.

The backbone of DAD-IS is the Global Databank on Animal Genetic Resources, in which countries record data on their livestock breeds, including data on the size and structure of breed populations. Data are entered into the system by National Coordinators for the Management of Animal Genetic Resources, who are officially nominated by their respective governments. Countries take full responsibility for the completeness and quality of the data entered. More than 15 000 national breed populations (representing more than 8 800 breeds) from 182 countries are recorded. DAD-IS is the centre of an expandable global network of information systems that exchange breed-related data. A regional system (the European Farm Animal Diversity Information System – EFABIS) has been established in Europe and national systems have been established in a number of European countries.

In addition to the breed databank itself, DAD-IS provides links to other web-based resources, a number of tools for analysing breed population data, news on events and developments in the management of animal genetic resources, and the contact details of National and Regional Coordinators for the Management of Animal Genetic Resources.
