Endometritis is a kind of uterine infection that causes decreased fertility in cows. This study aimed to determine the effect of intra-uterine injection of super-oxidized water on the improvement of the clinical symptoms in the cows with Endometritis. The study examined 60 dairy cows 25 days or more in the postpartum period. Thus, 80 cows with different degrees of Endometritis were selected applying rectal examination and vaginoscopy and their endometrial thickness was measured and recorded applying ultrasonography. Finally, about 20 cows were withdrawn from the study due to reasons such as withdrawal from the herd. 60 remaining cows that received treatment were divided into 6 groups based on their degree of Endometritis; 3 experimental groups and 3 control groups. Control groups received the common treatment by antibiotics and Metricure while the experimental groups were treated by intrauterine injection of 50 ml of super-oxidized water. The results indicated that after the treatment, the cows in the experimental groups were significantly different from the cows in the control groups considering the endometrial thickness, presence of infectious liquids in the uterus, and higher rate of successful conception compared to the number of inseminations. According to the significant results of the study, it can be concluded that applying superoxidized water in treating cows with Endometritis will be more effective.
