Subclinical Endometritis Diagnosed through Cytobrush and Reproductive Performance in Cattle from the Municipality of Pupiales, Colombia

Abstract

<em>Objective</em>: To determine the distribution of subclinical endometritis and the reproductive behavior of dairy cattle diagnosed through endometrial cytology from the Municipality of Pupiales, Nariño. <em>Materials and methods</em>: A reproductive assessment was carried out (rectal palpation, ultrasonography and evaluation of vaginal mucus) to determine the absence of early gestation and of clinical signs of uterine infection, and 174 cows were sampled through cervical catheterization and the technique of Cytobrush starting 30 days after birth. Consequently, the population under study was organized based on ovarian function (empty cycling normal or anestrous) and the status of the uterus (with or without endometritis). <em>Results</em>: 43 cows (24.7%) showed cellular changes indicative of an active inflammatory process originated in the endometrium. 79.06% of the animals diagnosed with subclinical endometritis were cyclic and had low reproductive performance. <em>Conclusion</em>: The high impact of subclinical endometritis in fertility and reproductive efficiency was determined. An early reproductive assessment must be performed, together with tests that make it possible to determine the presence of concomitant subclinical conditions.
