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. |
