This booklet provides an introduction to the eponymous animal genetic resources. A brief overview of the history of animal genetic resources management in Lithuania from the post-First World War period to recent times is followed by short descriptions and histories of individual breeds of horse, cattle, pigs, sheep, goat, goose, dog and bee. Several of these accounts describe factors that have driven native breeds towards extinction, and the steps that have been, or should be, taken to conserve them. The booklet is illustrated throughout with colour photographs.
