The infection rate and intensity were highly variable by age, the highest rate was found in the chickens at 3 - 6 months old (50.75%) and the lowest rate was found in the chickens over 6 months old (30.64%). The infection rate of chicken in summer-autumn was higher than that in winter-spring (51.42% versus 43.50%). The out-door raising chickens were infected with the highest rate (58.61%) and the in-door raising chickens were infected with the lowest rate (29.09%). Time for roundworm eggs developing into larvae in summer was shorter than in winter.
