Abstract:
The objective of present study was to evaluate the prophylactic efficacy of intrauterine ozonated oil (TRIOMET^TM, Trieen Health care, Bengaluru), on uterine involution period as well as uterine involution pattern by assessing the reduction rate in previously gravid uterine horn diameter, cervical diameter, previously gravid uterine horn length and intrauterine fluid (IUF) in postpartum(pp) crossbred dairy cows. Thirty-six normally calved crossbred dairy cows were randomly divided into 3 groups with 12 each. Group I served as control and Group II and III received one time and two time intrauterine ozonated oil (100 mL) on day 5-7 and 14, respectively. Uterine involution pattern assessment was carried out by employing USG and per rectal examination on day 7, 14, 21, 28 and 35 pp. The intrauterine administration of 100 mL of ozonated oil either one-time or two- times prophylactically, did not hasten either the rate of reduction in previously gravid uterine horn diameter and length or cervical diameter compared to the control group. The involution period recorded for all the cows in different study groups did not show significant difference (Group I vs II vs III; 35.83 ± 0.43 vs 35.50 ± 0.37 vs 34.83 ± 0.84). Ultrasonographic and per rectal examination of postpartum uterus in normally calved cows during the study period revealed that intrauterine ozonated oil used in the study did not have significant effect in hastening the uterine involution rate.
