%X The objective of current study was to evaluate the association of uterine health between serum glucose and beta hydroxybutyric acid (BHB) levels, body condition score (BCS), calving type (eutocia or dystocia), calving season (summer or winter) and parity in Holstein dairy cows and to determine the cut-off levels for these parameters. While cows without any reproductive problems during calving and pp 50 days enrolled into control group (n:27), cows with metritis and endometritis in the same days included the other one (n:33). BCS were recorded at dry period (-60 days), calving and pp 30 days. Blood samples were collected at d 21¡À3 prepartum and d 15 and d 35 for determination of glucose and BHB levels. Parity, calving type and calving season of cows were recorded and their relationship with uterine health were evaluated. Receiver operating characteristics (ROC) curves for BHB, glucose and BCS were used to determine the cow-level thresholds for the development of uterine problems. In addition, pairwise comparisons of area under the curve (AUC) of ROC curves for the thresholds of glucose, BHB, BCS predicting uterine problems were determined. While the BHB concentration were higher, glucose concentration were lower at 21¡À3 days prepartum and 15 days postpartum in cows with uterine problems. Serum glucose and BHB concentrations at 21¡À3 days prepartum and 15 days were also the best predictor for the diagnosis of uterine problems. However, BCS had no significant effect on development of uterine problems. There were also no significant effect of parity, calving season and type on development of uterine problems. In conclusion, serum glucose and BHB concentrations were the risk factors for uterine problems but BCS had no significant role on development of uterine disorders
