The Drimmon (aka Droimeann) is white-backed and considered an authentic color variety — and it’s rare.
The Drimmon is possibly a Longhorn descendant or a cross of the Kerry and the Irish Moiled.
A Drimmon named ‘Big Bertha’ is in the Guinness Book of World Records for reaching the age of 48years and eight months — and birthing 39 calves!
(Gaelic) droimeann = white-backed
