The objective of this study was to compare the efficiency of two methods (vaginoscopy and ultrasonography) for the diagnosis of clinical endometritis. A total of 142 cows from commercial herds from south of Minas Gerais were submitted to two methods of diagnosis, ultrasonography and vaginoscopy (gold standard), between 20 and 40 days postpartum. The period of service and the conception rate at the first insemination in animals with or without endometritis diagnosed by vaginoscopy, as well as the sensitivity and specificity of the ultrasonography for the diagnosis of clinical endometritis, analyzed by the chi-square test, while the Wilcoxon test was used to analyze the variables. The incidence of endometritis was 36% (n=51), cows diagnosed positive in vaginoscopy had a longer service period (120,87 ± 45,95 days) than the negative animals (102,05 ± 45,69 days). Positive animals in vaginoscopy had a lower rate of conception in the first service, 37,2% (n=51), compared with the negative animals 44,3% (n=88). Ultrasonography showed low sensitivity (47.1%) compared to vaginoscopy, which is considered a gold standard method, and was a poorly diagnosed method for diagnosing positive animals, but with good specificity (79.1%). It was observed that 13% of cases of clinical endometritis considered negative in vaginoscopy were positive on ultrasonography, probably because the animals had closed cervix and uterine secretion absent in vaginoscopy examination. Associating undiagnosed animals positive for vaginoscopy and low sensitivity of ultrasound examination, the ideal is to use the combined method (association of vaginoscopy and ultrasonography) to diagnose clinical endometritis, which resulted in good accuracy (86.6%). Ultrasound examination is able to diagnose positive animals that go unnoticed in vaginoscopy. The use of the combined method as a gold standard for the diagnosis of uterine infection increased the identification of animals positive for endometritis
