I think the bulls should be given better odds, maybe chain the Matador to a canon ball, or a 'bullring' in the centre.
Chaining the bullfighter would be torture and the bullfighting has nothing to do with torture. Anyway, the bull has two good defense reasons.
Weight average value 300kg ♀ - 500 kg ♂
You have to be very brave to get in front of that, I would not do it.
The fighting bull, also called brave bull, designates the male specimens of a heterogeneous bovine population1 developed, selected, and bred for use in different bullfighting shows, such as bullfights or bullies. They come from the autochthonous races of the Iberian peninsula, known as «Iberian trunk», which from time immemorial propitiated the most primitive forms of bullfighting. It is characterized by atavistic instincts of defense and temperamental, which are synthesized in the so-called "bravery", as well as physical attributes such as large forward horns and a powerful locomotor apparatus.
Casta Navarre: The Navarrese bulls, today nonexistent as such, were sierra bulls, small in size, with a bronco and chaste marked temperament that made up for their lack of showiness with aggressiveness and bravery.
Casta jijona: Recognizable for its many red hair specimens. Still today the animals of this coat are called jijones bulls.
Castilian or morucha-castellana caste: Big and hard bulls to fight.
Andalusian breed: According to José María de Cossío, it should occupy the first place in consideration for having been the one that has achieved the prototype and epitome of the fighting bull or fighting bull.
Casta cabrera: Large, long and agalgado body, with very developed defenses, from which come, among others, the specimens of Miura.
Casta vazqueña: Founded around 1780 by Don Gregorio Vázquez, gathering the best examples of Castilian and Andalusian herds. Acquired by King Fernando VII and, later, by the Duke of Veragua.
Casta vistahermosa: Founded by the Count of Vistahermosa in 1772, the breed from which most of the cattle that are currently struggling come from.
Casta Atanasio-Fernández: Bulls with large head, wide and with the antlers directed upwards, have a broad chest, a long and thick tail. Currently there are very few copies, it can be considered that it is in danger of disappearing.
Zoo interest
Unlike most breeds of domestic livestock, fighting bulls present a series of physical and temperamental characteristics more typical of a wild bovid, also highlighting the genetic information provided by its Y chromosome, which makes this breed unique. This should not be strange if one takes into account that when developing these breeds the breeders never intended to promote things such as increased production of meat and milk or a meekness and absence of stressed horns to make animals more manageable to human treatment , but simply sought to preserve (and even slightly enhance) a behavior somewhat more violent than normal that would make the animal more prone to the attack and therefore the bullfighting show. Certain authors such as the Dutchman Cis van Vuure have pointed out several coincidences in the body structure and common coloration of the fighting bull with those possessed by the now extinct European wild bull or uro, from which it differs for little more than its smaller size and length of horns During his life in semi-freedom in the dehesas, the fighting bull also maintains similar customs to those of a wild animal, forming herds, defending himself from possible dangers and performing an incalculable task in the middle.
