They are used as a draft breed and also for beef production. Even in the late 1970's these animals were still being used to pull fishing boats from the water.

Today the Mirandesa is grown for beef in the natural pastures of Northeast Transmontano, a region that is above the 500 m altitude. 
This region covers six counties of the District of Braganza which are: Miranda do Douro, Mogadouro, Vimioso, Vinhais, and Macedo de Braganza Knights. 

The Mirandesas natural beef quality and authenticity was recognised by the EU Commission through the allocation of a Protected Designation of Origin (PDO) for the "Beef Mirandese."

This breed is light to dark brown in colour with a curly fringe of hair on the head.
Mirandesa females average 133 cm in height and 550 kg in weight and are a lighter colour than the bulls. The males stand 143 cm tall and weigh 900 kg. Both sexes have short, broad heads with large white horns which grow outward and bend down and then forward, with dark tips.
