Hermaphrodite

[Keren]

Dun, were you using polled bucks over the polled does?

I have never studied the heritability but two polled animals bred together (goats) will give a CHANCE of intersexed kids. I am not sure percentage wise what the chances are though. If either the buck or doe is horned and the other polled, there is 0 chance of intersex.

According to what I've read on the subject, it's the buck that causes it - at least in meat breeds. The hermaphrodite gene is linked with the polled gene, and using a polled buck on does will result in approximately 25% of the kids being hermaphrodites.

This is as it happened to me. I was trying to increase the number of polled kids/goats in my herd and used a polled buck. I was warned ahead of time. On a positive note ~ s/he didn't have horns!

Both. I realize it's possible but I don;t think it's as common as suggested. Maybe we were just dumb lucky but we used the polled buck 2 years with probably aorund 75 kids total wihtout a problem.

ugh. I should have added ~ with all the doe's I bred to that buck, I only had one that was affected. And I used that buck for 3 years (about 20 kids).

Doesn't a female twin to a bull also exhibit both sexes sometimes?
The twin bull sometimes gets absorbed and you don't know she was a twin.

Correct

I bet that was the case with this calf.

I don't see the link between a sexuality mutation and the goat being polled, twinning and triplets are basically the norm in most goat breeds, while freemartins isn't usually a problem with goats I am sure the the higher incidence of twins will make the same scenario as what jeanne mentioned above more likely to happen from time to time in goats.

Its still just a mutation and like most mutations the exact cause will seldom be known.
