Lithuania committed itself to conservation of its genetic resources by signing the Conservation Convention on Biological Diversity in Rio de Janeiro on June 11, 1992. In 1995 FAO recognised the Vishtines goose breed as being monitored internationally and included into the FAO Global Databank for Animal Genetic Resources and the World Watch List for Domestic Animal Diversity. Vishtines geese are rather large in size with a medium-sized head, blue eyes and straight short orange beak. The arched neck is of medium length. The breast is broad and deep. The back is straight, horizontal and the shanks are long and orange. There are one or two skin folds on the abdomen. The plumage is white. The final body weight of the goose and the gander of this breed reaches 5 – 6 kg and 6 – 7 kg respectively.
Numerous scientific studies have been made with these geese in Lithuania. Biochemical protein polymorphism and microsatellite analysis tests with the goose breeds grown in Lithuania indicated that Vishtines goose breed is unique and can be distinguished by biochemical genetic individuality.
