In an attempt to experimentally reproduce focal ulcerative dermatitis (FUD) in turkeys, pressures of 94, 136, and 240 mmHg were applied for 2, 4, or 6 hr daily for 4 consecutive days to unfeathered breast skin of six 9-week-old toms. No gross lesions occurred either immediately after treatment or during a 10-day post-treatment period, and no microscopic changes were present in the skin at the conclusion of the trial. These findings suggest that avian skin is resistant to pressure-induced decubital ulceration and that pressure is unlikely to be either the cause of or a significant contributor to FUD.
