What do Mertolenga cattle look like?
The Mertolenga is a Portuguese breed of cattle, kept now above all for beef. Its name comes from Mértola, a concelho, or district, in the south-eastern corner of Alentejo, close to the Spanish frontier. It is a southern Portuguese animal with a long working history; for generations it was a draught beast rather than a meat one. It belongs to the group of cattle breeds registered in Portugal, and its beef is sold in part under the name Carne Mertolenga, which holds Denominação de Origem Protegida status.
Where does the Mertolenga come from?
The Mertolenga grew out of the Alentejana, the cattle long kept in Alentejo in south-eastern Portugal. A colour form among them was identified in 1873, and from that point the Mertolenga was treated as a breed in its own right. The Berrenda en Colorado of Spain is among its ancestors. Herds today are concentrated in the south of the country, in Ribatejo and the Low Alentejo. Thirteen cattle breeds were on Portugal's official register in 2003, and the Mertolenga was among them; together they accounted for about 19 per cent of the national herd.
What the Mertolenga is known for
The breed is remembered for what it did rather than for one striking feature. As a draught animal it worked in the rice fields of Alentejo, and it was also kept to help with fighting bulls, moving and holding them for the people who handled those animals; the Berrenda en Colorado does the same job in Spain. Through all of that it has stayed a southern Portuguese breed, at home on the low ground of Alentejo and Ribatejo rather than in the hills.
How the Mertolenga is bred and kept
Registration defines the breed. It has stood among the thirteen cattle breeds officially listed in Portugal since 2003, which keeps it as a named population rather than a loose pool of local cattle. The Mertolenga was first marked out in 1873 as a colour form of the Alentejana stock of Alentejo, and from that beginning it was carried forward as a breed of its own. The Berrenda en Colorado of Spain appears among its ancestors, and herds are kept chiefly in the Low Alentejo and Ribatejo.
Mertolenga, drawn
What the Mertolenga is kept for
For a long time the Mertolenga was a working breed. Oxen drew carts and ploughs in the rice fields of Alentejo, and the cattle were also used in the management of fighting bulls, moving and containing them before and during the events. The Berrenda en Colorado fills that role in Spain. Money now comes from meat instead: cattle are fattened for beef, and part of the beef is sold as Carne Mertolenga, a name carrying Denominação de Origem Protegida status.
The land and climate of the Mertolenga
The Low Alentejo and Ribatejo are the breed's home ground, in southern Portugal near the Spanish border. Working life took the cattle into the rice fields, where water stands over the land for part of the year. Mértola, the district that gave the breed its name, sits in the south-east of Alentejo beside the frontier.
Custom and folk tradition
Old working habits are what local memory holds. The Mertolenga was a plough and cart animal in the rice fields of Alentejo, and it was kept for the needs of bull handling as well, helping to shift and hold fighting cattle. Across the border in Spain the Berrenda en Colorado is put to the same sort of work, and that border country is where the breed has always belonged.
Numbers, conservation and the herd book
The figures kept for the breed show a secure place in Portuguese farming. In 2003 it was one of the thirteen cattle breeds on the national register, and those breeds together made up roughly 19 per cent of all cattle in Portugal. The FAO judged it not at risk in 2007, and DAD-IS came to the same conclusion in 2022. Part of its beef is marketed under the Carne Mertolenga name, which has Denominação de Origem Protegida status.
