OZONE THERAPY OF RETAINED PLACENTA IN HOLSTEIN COWS

The aim of research was to evaluate intrauterine ozone therapy in Holstein cows with retained fetal membranes (RFM). Research is performed on 45 Holstein cows aged 2-6 years divided in three groups. The first group (n=15) consisted of cows treated with foam spray ozone application with sterile catheter in the body of the uterus for 5 seconds. The second group (n=15) was consisted of cows treated using 6 ozone perls. The third group or control group (n=15) was consisted of cows treated with foaming tablets (oxytetracyclin). Cows were observed and treated during early puerperium, 24 to 36 hours after parturition. To assess the reproductive performance of cows, interval from calving to first insemination (days open to first service, DOFS), interval from calving to pregnancy (days open to pregnancy, DOP), and all service conception rate (ASCR) were measured. Conception rate was 1, 80 in the first group, similar to control group (1, 73) and 2, 07 in cows treated with ozone perls. In first group, days open to first service was 101, 06 ± 16, 29, in second 108, 53 ± 16, 09 and the third 104, 53 ± 13, 56 days. Days open to pregnancy was shortest in the first group (118, 06 ± 24, 85), but the longest in cows treated with ozone perls (133, 20 ± 26, 96) and 121, 20 ± 32, 32 days in cows treated with OTC foaming tablets. Cows with RFM treated with intrauterine Riger spray or Ripromed ovuli O3 have similar reproductive performance results as in control group of cows which proves the effectiveness of therapy with intrauterine ozone products.
