The objective of this study was to identify test parameters and cutpoints
in the peripartal period allowing the identification of cows at increased
risk of postpartum uterine disease (PUD) according to the definition of
Sheldon et al. (2006) (puerperal metritis, clinical metritis, clinical
endometritis). In eight herds blood serum of 96 cows were collected
weekly during the period of 2 weeks before expected calving (-2 wk)
until 2 wk postpartum. Postpartum uterine disease was detected by
clinical examination up to fifth week postpartum. There were 40 cases
of PUD (group 1) and 56 cases of no postpartum uterine disease
(NPUD; group 2). Significant differences were detected in Bilirubin,
AST, BHBA and Albumin. Predictor cutpoints of these parameters
were calculated by ROC Curves. The cutpoints of different parameters
were compared with each other considering sensitivity (sen) and
specificity (spec) and odds ratio (OR). In PUD higher concentrations of
Bilirubin from wk -1 to wk 2 (P
