Abstract:

Metritis is one of the main factors of postpartum infertility in rows, and as a result reduces reproductive performance in dairy herds. In this study, the uterus of cows were sampled using swap Double Guard after 7 or 8 days of childbirth, the based on the number of counted colonies (more than 10 colonies) are divided into two groups. In the first group (19 cows) were subcutaneous undergone. Ceftiofur for three consecutive days from 10th day after birth and second group (16 cows) received no treatment. Blood sampling was performed on 28, 21, 14 and 7. The result showed that estrogen in ceftiofur group reached to the maximum blood level on day 14 in the first month after birth. Also progesterone in ceftiofur group was significantly higher than control group on day 14. Progesterone one was the maximum on day 28 in both groups, which it is higher ceftiofur group than control group. But there was no significant difference. It is generally observed that estrogen production was significantly higher than control group after drug use especially cows with several births showing drug’s effect on the group. Also progesterone in ceftiofur group is significantly higher especially in cows with more than one birth. So it can be concluded that ceftiofur by affecting on uterine Bacteria can influence estrogen and progesterone secretion.
