The present study was conducted in order to examine the effect of monensin on serum level of haptoglubolin in pregnant dairy cattle. About 20 heads of pregnant dairy cattle (5 months pregnant) were selected in two, control and treatment, groups. The cattle of two groups were in the same situation considering management, production and age. In treatment group about 200 mg monensin was added to the diet of each cattle head in addition to the ordinary diet of control group. On days of 0, 30, 90, 120, time of parturition and 2 weeks after parturition the blood samples was collected from jugular vein. and then serum was separated. In all serum samples the haptoglobin serum level was measured by biochemical kit. The average of serum haptoglobin did not have meaningful difference between two groups on day of zero but in care group there was decrease in serum haptoglobin after the day of 30 and on the day of 30 the difference between two groups was not significant (p = 0.066). On the day of 90 and 120 this difference was significant and it was p = 0.037 and p = 0.04, respectively. On parturition time, haptoglobin serum level increased in two groups and this increase in treatment group was less than control group which was nonsignificant (p = 0.003) and 2 weeks after parturition it was low in treatment group which was not significant (p = 0.586). The changes of serum haptoglobin in control group was not meaningful on different times but in treatment group the serum changes was significant on days of zero and 30 (p = 0.04). The mean serum level of this protein in affected cattle to parturition diseases was greater than healthy carrel in two groups. Final result was that adding monensin to pregnant cattle diet led to decrease of haptoglobin serum level, 4 month before parturition.
