Cow's/Mooshroom's udder texture is wrong

While looking at the textures of a cow, I realized that the belly didn't match the back, because the parts of the udder was incorrect. The udder is shifted one pixel to the right (right as in perspective of the cow) and therefore it doesn't match the physical udder itself.

I have posted about this problem at the link below with a picture without the udder to show you the problem:
