After noticing an alarming difference in sow body conditions in several herds, Cary Sexton, DVM, became concerned.
Environmentally controlled hog facilities eliminated most swine parasites. But Ascaris suum (roundworm) continues to persevere on some conventional farms and frequently on farms for niche markets.
