The aim of the study was to assess changes in the vaginal bacteria load, at different times following treatment with intravaginal Progesterone implants. Thirty postpartum (>70 days) anestrus crossbred cows were treated with three standard hormonal protocols (CIDR Gr. II, TRIU-B Gr. III and P4 Sponge Gr. IV protocols, n=10 each), and the findings were compared with a group of untreated (n=10) anestrus cows which were inserted with blank sponge (containing no P4). Vaginal swabs were collected from each treated cow, prior to insert/sponge insertion and at the time of insert/sponge with draw a land on the day of estrus for bacterial load. The total bacteria count obtained from swabs collected at implant insertion showed no significant difference between CIDR (2.15 ± 0.53X104), TRIU-B (2.14 ± 0.40X104) and P4 Sponge (2.33 ± 0.68X104) implants as well as Control group (2.24 ± 0.92X104) and increased significantly in all groups (P<0.01) at the time of implant removal viz. 1.80 ± 0.35X105, 2.22 ± 0.57X105, 2.58 ± 0.71X105 and 2.36 ± 0.63X105 respectively in CIDR, TRIU-B, P4 Sponge, and control groups. As expected, after 48 hours of implant removal, total bacteria count obtained showed no significant difference (2.71 ± 0.71X104, 2.85 ± 0.78X104 and 2.96 ± 1.2X 104) with that of obtained before implant insertion in all the groups of animals but in control group (placebo) the total bacterial count was significantly (P<0.01) higher (2.02 ± 0.25X105) even after 48 hours after the implant removal. Furthermore, there was no significant difference in total bacterial count at the time of insertion, removal and 48 hours after insertion between CIDR, P4 Sponge and TRIU-B groups but the total bacterial count in control group was significantly higher (P<0.001) at 48 hours after sponge removal than those of CIDR, P4 Sponge and TRIU-B groups (P<0.01).
