This study identified retained placenta, metabolic disorders, and parity as risk factors for postpartum endometritis in Korean dairy cows, which subsequently reduced reproductive performance by prolonging calving-to-conception intervals and lowering conception rates.

This study investigated risk factors for postpartum endometritis and its impact on reproductive performance in 320 dairy cows across eight Korean herds. Logistic regression analysis identified retained placenta, metabolic disorders, and parity as significant risk factors for developing the condition. The presence of endometritis significantly prolonged the intervals to first service and conception while reducing conception rates and increasing services per conception. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

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.
