A device is inserted into the vagina of a female animal, such as of the bovine, porcine ovine, equine, or caprine species. Long-term retention enhances the quality and quantity of meat produced by the animal. In one embodiment, the device includes a central shaft which carries two axially spaced mounting rings to which are affixed a plurality of elongate resilient rods which radiate to terminate in free ends of enlarged bulbous configuration. The device is inserted into the animal's vagina with a speculum. The bulbous ends of the rods are urged to engage and become embedded in the animal's vaginal lining for long-term retention. -1-
