Welsh black cattle are large, black animals with black-tipped horns, although some strains may yield polled ones. An occasional white may appear underneath, and depending on the presence of the recessive red gene, individuals of red color might occur also.
The amalgamation of two separate strains of Welsh black cattle, namely the North Wales strain, previously used solely for beef production, and the South Wales or Castlemartin strain, used primarily for milk production, has created the modern Welsh Black cattle breed that possesses the prized characteristics of both strains.
Although the animals continue to be raised traditionally both for their milk and their meat, the commercial focus is solely on beef production. The beef obtained from Welsh black cattle is of high quality and is distinguished by excellent muscle mass and very low fat content.
