Abstract

Three species of parasitic intestinal fluke have been identified in backyard chickens in 3 districts of Thai Nguyen province, including: Hypoderaeum conoideum, Echinostoma revolutum and Notocotylus intestinalis. The rate of intestinal fluke infection in 3 districts of Thai Nguyen province is 16.33% with the intensity from mild to very severe, in which the infection is mainly at mild and moderate intensity. Phu Binh district has the highest rate and intensity of intestinal fluke infection (18.94%), followed by Dong Hy district (15.38%) and the lowest is Phu Luong district (14.41%). Chicken over 6 months old infected the highest (21.55%), decreased to 16.89% in the period> 3 - 6 months old and lowest in the period ≤ 3 months old (9.86%). Chicken raised in Spring - Summer crop infected with intestinal fluke, higher than that in Autumn - Winter crop (20.10% compared to 11.92%). Time of egg development to Miracidium in water environment in Spring - Summer is higher than Autumn - Winter crop.
