We named her when she was just a weaned heifer. When she grew up, I realized that "Petunia" was most appropriate, i.e. Petunia Pig was Porky Pig's girlfriend! Actually she is not fat in the photo---that rear end is muscle.
Here she is at the end of a really good grazing season...a little fat(see the fat pads around her tailhead and under the tail):
But here she is with a newborn calf....the rear end is still there but no fat around the tailhead:
