I've never seen anything like that! Looks like someone was going to do surgery and sliced him open. Probably the best thing to do would be to get ahold of him and check it out closely or maybe have the vet take a look. Has it always been that way? Looks like it could get infected very easily :? I agree with Katherine that it might be some sort of hermaphrodite or related issue. Hope you figure it out.
If that was my calf I would call Dr. U and send him a pic and find out if he has ever seen anything like it before, if he had no idea I guarantee he would drop by to take a look when he is in the area..
That is very odd and you will get diddly for it if you are planning to sell it with that visible, call your vet and see what they think (it is usually a free call)..
Keep us posted if and when you find out,,very odd indeed.. :?
very interesting. Does he/she act like it hurts? running/playing like normal? in the picture it looks like it licking it like a wound. My first thought was it looks like the calf straddled a wire fence...???? is it open? deep? bleeding? puss/discharge? you should catch the calf and take a close look.
