The prevalence and infection intensity increased in accordance with duck’s age. In spring and summer seasons, the infection rate of ducks was higher than in autumn and winter seasons (28.30% and 33.01% compared to 17.35% and 12.90%, respectively). The ducks raised in good veterinary hygiene condition were infected with lower prevalence and infection intensity compared to the ducks raised in poor veterinary hygiene condition. The typical symptoms of the infection ducks included: high fever, slow blood clotting, anemia, weakness, slow movement, green stool diarrhea. The trial result of 2 treatment regimens for Leucocytozoonosis in ducks showed that both regimens have given high treatment efficacy (93.33 - 96.67%) and safety for ducks
