Retained placenta, metabolic disorders, and parity were identified as risk factors for postpartum endometritis, which in turn prolonged calving to first service and conception intervals and reduced conception rates in Korean dairy cows.

This study in eight dairy herds in Korea analyzed 320 cows calving between January 2001 and October 2002 to identify risk factors for postpartum endometritis using logistic regression on health status, parity, body condition score, and calving date. It found that retained placenta, metabolic disorders, and parity were important risk factors, selected via a stepwise modeling approach. Compared with cows without endometritis, those with endometritis had longer intervals to first service and to conception (by 23 and 36 days), lower first service conception rates, and required more services per conception. The paper relates to endometriosis/adenomyosis research through its analysis of postpartum endometritis as an inflammatory uterine condition affecting reproductive performance, though it does not explicitly discuss endometriosis or adenomyosis.
Abstract
The objectives of this study were to determine the risk factors for postpartum endometritis by evaluating several reproductive factors in individual cows, and to determine the effect of endometritis on the subsequent reproductive performance in dairy herds in Korea. The data, including health status, parity and body condition score (BCS) of cows, and calving date, were collected from 320 cows in eight dairy herds calving from January 2001 to October 2002. We used logistic regression to evaluate the effects of these factors on endometritis. A stepwise procedure, used to obtain the appropriate model with alpha=0.05, revealed that retained placenta, metabolic disorders and parity are the important risk factors for endometritis. The mean intervals from calving to first service and conception were prolonged (P<0.01) by 23 and 36 days, respectively, in the endometritis group compared to the non-endometritis group. The first service conception rate was lower (P<0.05) in the endometritis group (47.6%) than in the non-endometritis group (62.6%). The number of services per conception was higher (P<0.05) in the endometritis group (1.9) than in the non-endometritis group (1.6). We conclude that retained placenta, metabolic disorders and cow parity are strongly correlated with the development of postpartum endometritis, which decreases reproductive performance in dairy herds in Korea.
