Endometrial histologycal alterations were evaluated from repeated collection of uterine samples in Nelore (Bos taurus indicus) during the estrous cycle. Sixteen adult cows with a synchronized estrous cycle were used. The endometrial samples were collected in DO (day zero; ovulation day), D5 (day five), D9 (day nine) and D13 (day thirteen) of the estous cycle. Before the samples collections, we evaluated the ovary and the uterus by transrectal ultrasonography in all the animals. The mononuclear infiltrate was predominant, however their intensity wasn’t ranged throughout the estrous cycle, isn’t representing a direct consequence of the biopsies (P > 0.05). Intensity of polymorphonuclear infiltrate varied between harvests, being absent in the first and last sample (P < 0.05). So, we concluded that bovine endometrial biopsy is an adequate technique to evaluate uterine health.
