Factors that affect Feet and Leg Soundness
By Todd See, NCSU Swine Extension - The National Animal Health Monitoring System (2001) reports that structural, including feet and leg problems, unsoundness is the reason for removal of 16 percent of the culled swine breeding herd and accounts for 7.3 of the death loss in finishers. Factors that may affect structural soundness include genetics, level of production, sex, nutrition, disease, floor surface, equipment location and space.
