To determine the macroscopic and microscopic cysts of Sarcocyst 300 carcasses (138 male and 162 female) were inspected and samples were collected from muscles of heart, esophagus, diaphragm, triceps and shoulder, Daub smear were prepared and after staining were studied with microscope to find the microscopic cyst of parasite. X2 test was used to find the relation between the rate of infestation and age, sex and different muscles. Gross examinations declare in none of the samples, but daub smear method showed microscopic cysts in 91% of the samples. There was no significant difference between male and female for microscopic cysts (p0.05). Also in the cases with microscopic cyst, no significant difference was observed in different ages (p0.05). The results showed that there is significant difference among different muscles with microscopic cysts (p0.05), heart was the most infected and esophagus the lowest. Regarding to the results of this study the carcasses of the cow in Shahrekord are not infected to macroscopic cysts of Sarcocyst, but the rate of infestation to microscopic one is very high, it up to the kind of muscles and the rate of the muscle blood supply.
