Bovine theileriosis caused by Theileria sergenti is the tick-borne intraery- throcytic piroplasmosis, that occurs in most regions of Korea. It results in severe economic losses on a farm caused by anemia, milk production loss, abortion and death. This study was undertaken to confirm the effects of the growth hormone and the insulin-like growth factor-I which are associated in the growth of cattle infected by T sergenti. The blood of one hundred and twenty ten-month Holstein was collected and the prepared blood smear was stained with acridine orange to investigate their parasitemia. And the hematological profiles were observed. According to the value of the hematocrit, they were categorized into four groups : Group 1 was under 20 percent, groups 2 and 3 were from over 21 to under 30 percent and from over 31 to under 35 percent and group 4 was over 36 percent. As the value of the hematocrit decreased, parasitemia(%) in erythrocytes was observed to increase(Y=-1.064X + 30.537, r=0.660). The amounts of the growth hormone and the insulin-like growth factor-I in the serum were measured by the radioimmunoassay. The growth hormone in serum of the group 1, group 2, group 3 and group 4 were observed as
