Secreções uterinas em vacas leiteiras mestiças destinadas ao descarte na região do Triângulo Mineiro

Abstract

The considerable economic impact caused by the occurrence of uterine diseases in dairy cows intensifies research on the prevalence of uterine secretions and the ideal methods of diagnosis. The objective of this study was to determine the prevalence of endometritis and cervicitis in 453 pieces of the reproductive apparatus of dairy cows destined to slaughter and to verify the concordance between the presence of secretion in the cervical and uterine regions and the confirmation in cytology and histology. In addition, to evaluate the correlation between endometritis and cervicitis. Through the determination of the sensitivity and specificity and the Kappa index, it was verified that the agreement between the presence of secretion (uterine / cervical) and the endometrial and cervical cytobrush technique was low between the two diagnostic methods, it was also verified that Histology consists of a good diagnostic method, but more invasive and higher cost. Regarding the association of cervicitis and endometritis, low concordance was observed. Therefore, it is concluded that the diagnosis of uterine diseases performed only by the presence of secretions is flawed, and a cytological and, if possible, histological examination is necessary, helping to reduce reproductive problems and increase the reproductive performance of dairy cows.
