Compared to the hogs I have in the pen, I would say around 150 -175, and that would be on the high side.
I do not think the tail is cropped, because I have one of these cameras and it does not take very fine detail. I think the tail is just in a position that it can not be seen in the photo. But you could be right...
It definitely does look like a barrow, but again, it could be a cold night and the camera angle is not showing the goods.
