Kerry cattle are a rare breed of dairy cattle native to Ireland. They are believed to be one of the oldest breeds in Europe. Their coat is almost entirely black with a little white on the udder. The horns are whitish with dark tips. Cows weigh about 350–400 kg and produce 3000–3700 kg of milk per lactation. The breed is probably descended from the Celtic Shorthorn brought to Ireland as early as 2000 BC.
