A friend's daughter raised the State 4-H Grand Champion duroc gilt a couple of years ago. Decided not to sell her, but to breed her instead. That winter, she had a pig get hung up in the birth canal and died. But she did produce 2 new gilts and a barrow. One of the gilts went on to become over-all Reserve Champion.
One thing is certain. Livestock farming teaches kids all about the circle of life.
