Like Nathan, I have never heard or seen of this before in my short lifetime of livestock. I have seen a few oddballs including a sterile heifer that had the equipment on the outside but not a dang thing present on the inside and an udder like a steer.
Likely a female "freemartin", a twin to a normal male. (Perhaps the male was lost before/after birth and you thought it was a single birth when found on pasture). Twin calves blood mixes while in the womb, but the male calves hormones will overwhelm his sister's, causing the birth defect. Obviously this does not happen in humans.

The first birth in my summer calving herd is male/female twins (that is "one had balls, the other did not" ), a combination that occurs 50% of the time in twinnings. |
Calves born without anus?
