The goal of this work was to answer the question of whether or not there are significant differences between cows with abnormal vaginal discharge and cows with the diagnosis of puerperal or chronical endometritis, using blood and urine parameters. In addition, cows with and without vaginal discharge were examined for significant bacteriological differences in uterine mucous samples. The question of false positive and false negatives from the diagnosis of endometritis was also investigated. A total of 35 matched-pairs (±vaginal discharge) from 27 stables was examined 21 to 63 days post partum. The examination consisted of a rectal and vaginal exam, urine and blood samplesas well as vaginal swab from the corpus uteri using a Folmer-Nielsen-Catheter.[...] In a multivariate analysis with final step-back procedure regarding endometritis Gammaglutamyltransferase (GGT) and Betahydroxybutteracid (BHB) were significant different (p = 0.02). The hypothesis vaginal discharge alike endometritis showed that 34 % of the clinical suspicious cases were recorded as false negatives. In the non-suspicious cases 20 % were diagnosed as false negative.
