In total, 298 individual feral pigs trapped in the Northern Territory were tested for porcine parvovirus antibody (PPV), of which 174 (58.4 percent) scored as positive. The age of pigs ranged from 2 weeks to greater than 6 years. Most pigs had maternally-derived antibody at birth, which steadily decreased until about 8 months of age. Between 8 and 24 months of age, pigs rapidly acquired antibody to PPV, with 98 percent older than 24 months having antibody.
