A bull is an intact (i.e., not castrated) adult male of the species "Bos taurus". They are more muscular and aggressive than the female of the species, the cow. The bull has long been an important symbol in many cultures, and plays a large role in beef ranching, dairy farming. They are also important in other cultural activities, including bull fighting and bull riding. The management of livestock animals in hot climates is a challenge. The physiological and behavioral changes induced in these animals compromise their welfare, breeding, health, and zootechnical performance, resulting in final products (eggs, milk, and meat) with unsatisfactory characteristics.
