An Andalusian bull is mentioned in A Land Remembered by Patrick D Smith where can you learn more about this type of cattle?

Andalusian cattle, also known as Andalusian Blacks or in Spanish literature, Negra andaluza, Negra campiñesa, Negra de las Campiñas andaluzas,mostly has information on such a breed on breeder's sites that are Spanish and typically poorly translated into english. However, you still can get worthwhile information from such sites if you can make sense of what is being said as per efforts of translation from Spanish to English.

Basically, this breed is Spanish all the way through and few, if any, cattle of such breeding exist in North America. Andalusian blacks are found primarily in western Andalucía of Spain.

Basic information is found in the OK-State University Breeds of Cattle website on this breed. More information is found on the site Gemaga. Both links, and a couple others, can be viewed by clicking on such links in the Related Links section below.
