Known as an animal of multiple functions, the Equus asinus has always been used for various purposes, such as entertainment, horseback riding, means of transport, agricultural traction and dairy farming. Although, donkeys are associated with a vast heritage of social, cultural, economic and ecological importance, they have lost their importance in the activities of rural properties, both in the developed economies of European countries and in the Northeast region of Brazil. Specific studies of production systems aimed rational exploitation of the donkey species in Brazil do not exist. New perspectives for the use of donkey in the Brazilian semiarid region through the dairy industry has aroused scientific interest and the interest of investors. The donkey, allied to the low production costs and rusticity of the species, has the capacity to contribute to the economy with products of high biological value and therapeutic characteristics. Thus, this review provided a broad view of the donkey bred in the Northeast of Brazil, observing its characteristics and relevance for the region. The benefits of donkey milk and the need to promote the production and marketing of this milk in the dairy production chain will also be discussed.
