Maronesa is a hardy breed from the Trás-os-Montes region in northern Portugal, living in what is still wolf-country. Some lineages are very aurochs-like. The bulls are much larger than the cows, with a dark brown to black coat colour and a light eel stripe, a lightly coloured muzzle and very large horns. Maronesa cows are reddish-brown. The bulls’ heads are large and they are well muscled with a curved backline from the strongly pronounced shoulder part. The horns are thick and point forward. Maronesas are used to harsh conditions with snowy winters and hot summers and able to live without any human management, with calves growing up successfully also with wolves around.
