Spanish Fighting Bull

The Spanish Fighting Bull (Toro Bravo, toro de lidia, toro lidiado, ganado bravo, Touro de Lide) is an Iberian heterogeneous cattle population. It is primarily bred free-range on extensive estates in Spain, Portugal, France and Latin American countries where bull fighting is organized. Fighting bulls are selected primarily for a certain combination of aggression, energy, strength, and stamina.

Some commentators trace the origins of the fighting bull to wild bulls from the Iberian Peninsula and their use for arena games in the Roman Empire.

Although the actual origins are disputed, genetic studies have indicated that the breeding stock have an unusually old genetic pool.

The aggression of the bull has been maintained (or augmented, see above) by selective breeding and has come to be popular among the people of Spain and Portugal and the parts of Latin America where it took root during colonial rule, as well as parts of Southern France, where bullfighting spread to during the 19th century.

In May 2010, Spanish scientists cloned the first of the breed. The calf, named Got, meaning "glass" in Valencian, was cloned from a bull named Vasito and implanted into a Holstein host mother.

The fighting bull is characterized by its aggressive behavior, especially when solitary or unable to flee. Many are colored black or dark brown, but other colorations are normal. They reach maturity slower than meat breeds as they were not selected to be heavy, having instead a well-muscled "athletic" look, with a prominent morillo, a complex of muscles over the shoulder and neck which gives the bull its distinctive profile and strength with its horns. The horns are longer than in most other breeds and are also present in both males and females . Mature bulls weigh from 500 to 700 kg (1100-1600 lb).
