Utah farmer witnesses rarity: 2-headed calf


YOUNG WARD, Utah (AP) -- A northern Utah farmer is donating a rarity to Utah State University for research: a two-headed calf.






The calf was delivered by a veterinarian Wednesday night on Brad Tolman's farm in Young Ward.






Logan's Herald Journal reports (http://bit.ly/WHRIbL ) that while the calf was alive when labor started, it had died by the time it was delivered.






Veterinarian Aldon Watkins says it was only the second two-headed calf he has delivered.






USU veterinary technician Sarah Behunin says the two-headed calf will be used by veterinary students to study birth defects.






She says it's unclear why two-headed calves occur, but a popular theory is that an egg begins dividing into identical twins but doesn't finish the process.






The Angus heifer that gave birth is expected to make a full recovery.
