a male cow, or the male of particular animals such as the elephant or the whale
We saw a bull elephant.
The rancher kept a herd of bulls for breeding purposes, carefully selecting the strongest and healthiest ones to sire the next generation of cattle.
The bull was easily identifiable among the cows in the field due to its muscular build and distinctive horns.
The bull's aggressive behavior during mating season required the rancher to take extra precautions to ensure the safety of the farm's workers and other livestock.
