Negative Impact of Metritis and Endometritis on Reproductive Performance in Dairy Cattle
Journal Title: Journal of Veterinary Medical Research - Year 2017, Vol 24, Issue 2
Abstract
The current study was conducted to investigate the incidence of metritis and endometritis in dairy cows. Moreover, to determine the collective impact of metritis and endometritis in dairy farms on reproductive performance and milk yield. A total number of 246 Holstein cows divided into three groups was included in the current study.One of these groups as control group and the second and the third groups were including those cows diagnosed with acute postpartum metritis and chronic endometritis, respectively. The obtained results showed that endometritis possessed severe negative effects on postpartum reproductive performance of the studied cows compared to normal cows. Moreover, the impact of this disease was higher in premiparous cows in comparison with com their pleuriparous herd-mates. Days to first estrus tended (P=0.06) to be increased in premiparous cows suffering from endometritis (89.19±12.12 days) compared to normal cows (59.45±3.30 days) or those suffering from acute metritis (65.37±4.92 days). While in pleuriparous cows, the negative effects of endometritis did not show any tendency for prolonged days to first estrus, when compared to normal cows. Endometritis had significantly (P<0.01) negative impacts on postpartum cyclicity in premiparous cows (89.19±12.12 days), compared to 56.32±3.15 days in pleuriparous cows. Endometritis, significantly negatively (P<0.05) impacted days to first AI in both premiparous cows (105.63±12.95 days, compared to 65.97±2.63 days for normal cows and pleuriparous cows (76.19±3.64 days). A nearly similar trend was observed for endometritis and metritis regarding their potential negative impacts on number of inseminations per conception in both premiparous and pleuriparous cows. Regarding to, days open, diseases like endometritis was associated with significantly (P<0.01) higher days open in both premiparous and pleuriparous cows. Meanwhile, advancing parity was associated with significantly (P<0.05) higher days open for cows suffering from endometritis only.
