As a result, theaverage infection rate of ducks with Prosthogonimus sp was 30.41%
there was no significantdifference of the infection rate of ducks in the three provinces. The infection rate was dependedon the duck age groups, the lowest infection rate was at the age group ≤ 8 weeks old, followedby age groups from 9-24 weeks old and >
24 weeks old. The infection rate of ducks raising in theplain area was 36.25%, It was higher than that in the mountainous area (24.58%). The infectionrate in the rainy season (38.33%) was significantly higher than that in the dry season (22.8%).The infection rate of duck raising in the semi-outdoor and indoor raising systems was 21.97% and38.96%, respectively (P0.05)
