Abstract

The in situ peak rarefactional pressure threshold levels in crossbred pigs at three ages, 4.9±1.6-, 39±5-, and 58±5-day-old, were studied. Lung hemorrhage was ultrasound-induced at varying exposure conditions. Overall, the oldest pigs were most sensitive to lung damage, and neonates were more susceptible than middle-aged pigs.
