Abstract: In the present research, hemoglobin polymorphism was studied in two Iranian important sheep breeds; Moghani and Makouei type. Eighty eight samples from age groups and each breed were selected. Determine of the hemoglobin phenotype carried out with acetate cellulose electrophoresis method. Two hemoglobin phenotypes includes AA and AB were observed in the studied breeds. In Moghani breed AA and AB phenotypes frequency were in 71.6 and 28.4%, respectively and in Makouei breed were as below: AA in 69.3 and AB in 30.7% of the sheep. In sheep with AB phenotype, the amount of B hemoglobin was more than A but difference between A and B haemoglobins levels were not significant between the two breeds. The total amount of hemoglobin in Makouei was more than Moghani breed and there was a significant difference between two breeds concerning total hemoglobin. According to the results of the present research, C and F hemoglobins present to one month of age and by the increase of age, the amounts reduce gradually and reach to around zero after 2 month of age.
