| Abstract | |
Reproductive diseases are a great barrier to the dairy production, as it diminishes fertility and causes economical losses with treatment costs and lowering production. In this context, endometritis plays an important role. There are different diagnostic techniques for endometritis, rectal uterine palpation vaginoscopy, microbiological tests, uterine biopsies, endometrial cytology and ultrasonography, these tests vary in sensitivity and specificity. This work had as an objective evaluating and comparing vaginoscopic, ultrasongraphic and histopathological examinations, as well as their associations, for the endometritis diagnosis by determining their sensitivity, specificity and kappa agreement coefficient using endometrial cytology as gold standard. It was necessary developing an adaptive reading score to perform the uteris histological examination. In this study 106 female Holstein cows were submitted to a gynecological examination. The ones that had no vaginal catarrh were submitted to an ultrasonographic examination, to endometrial cytology examination and uterine biopsy. Results shows that ultrasonography is a practical and good diagnostic method, the association between the determination of intra-uterine fluid and cervical diameter was the most efficient ultrasonographic method, with 50%, 88% and 39% of sensitivity, specificity and agreement coefficient kappa respectively. Histopathological examination was good diagnostic method, even though not as practical as ultrasonography (AU) | |
