Intrauterine ozone administration for improving fertility rate in Simmental cattle

The objective of the study was to determine whether fertility in cows can be improved by post partal intrauterine ozone administration. The cows were divided into two groups - treatment (T) and control (C). The treatment group received 20 mL of ozonated foam into the uterus within 6 hours after calving and 24 hours later. Control group received no treatment. The outcome measurements were the number of days open and the number of artificial inseminations until pregnancy. The ozone was found to be effective treatment modality, resulting in a shorter period of days open (75.47 vs. 98.03, P<0.05), and fewer inseminations until pregnancy (1.68 vs. 2.42, P<0.05) in treated cows compared to the control group. Postpartal intrauterine ozone flush, coupled with intracornual insemination represents an effective treatment option that could lead to an improved fertility rate in Simmental cows.
