This study included the investigation of blood parasites in 150 geese. The results showed a high infection rate of 70.7%. The infection rate in the geese with small ages was higher compared to the large ages with 84.2 and 47.3% respectively, with no significant difference in infection rate between males and females. The highest infection rate of the parasite is Aegyptianella sp
. 26.4% followed by Haemoproteus sp., Plasmodium sp.
, Leucocytozoon sp.
and Trypanosoma sp
. with infection rates of 19.8, 18.9, 14.2 and 2.8% respectively, as well as micro larvae of Microfilariae sp
. with an infection rate of 17.9%, the two-type infection was the highest, with 45.3%. Microscopic examination of stained blood samples during laboratory experiments showed microscopic developments of the ookinete, which appeared within five hours after blood exposed to air and the ookinete measurement rate was 19.5 × 2 microns.
