Devil's claw (Harpagophytum procumbens) in a Brahman's preputial sheath : a case report from Botswana : case report

Abstract

Failure of penile protrusion during attempted service of a cow on heat was investigated in a 3-year-old Brahman bull at Kwakwadi cattle-post in the Kgalahadi sandveld, Kweneng District, Botswana. The investigation revealed that penile protrusion was obstructed by a devil's claw (grapple thorn), a dry fruit of the plant Harpagophytum procumbens, which had lodged in the cavum preputiale. The thorn, which was removed almost completely manually with minimal tissue dissection, had also caused minor lacerations and puncture wounds on the lamina interna pars parietalis. The wounds healed well following treatment with antiseptics and antibiotics and subsequently the bull regained full penile protrusion and served the cows well. This report describes the first case of lodgement of a devil's claw fruit in, and its extraction from, the cavum preputiale of a Brahman.
