Connective tissue replaces muscle in the forelegs of afflicted pigs resulting in legs that appear thick and swollen. This disorder is recessively inherited, but can be caused by non-genetic factors such as ingestion of Jimson weed or tobacco by pregnant sows. While it is now known that additional nipples are not associated with enhanced fecundity, the idea was still taken seriously by medical practitioners as recently as the 1800s. So, as you can see, there are many ways in which we can sow righteousness. If it occurs in nearly every litter by a boar and the dams are unrelated, look for environmental influences; otherwise, dominant gene action is implied and the boar usually would exhibit the defect already.
