teaser(redirected from teaser bull)
Also found in: Dictionary, Thesaurus, Legal, Encyclopedia.
an animal used to sexually tease but not to impregnate the members of the opposite sex. Usually males and they may be surgically prepared to ensure that they cannot mate or are not fertile. In cattle and sheep vasectomized animals or castrates injected with testosterone are used; in horses an entire or cryptorchid is used but at a distance so that no act of mating can take place.
male goat used as a teaser.
a bull that is used to make sexual advances to cows and detect those that are on heat without being able to fertilize them; this usually means that physical mating cannot occur but vasectomized bulls are able to do so. More commonly the bull has been altered surgically so that the penis is diverted or the bull wears an interfering harness.
