Abstract

Introduction: This study aimed to evaluate the morphology of the genital tract from 98 Nellore cows by rectal palpation and combine them with the functional aspects for inclusion in a fixed-time artificial insemination (TAI) program. Methods: Were evaluated the ovaries, cervix and vulva, as well as the body condition score (BCS scale 1-5). Results: In relation to the ovaries, there were palpable structures found in 51 (17 CL and 34 FL) in the rights ovarian and 37 palpable structures (06 CL and 31 FL) in the left ovary. Asymmetry was found in 17.3% and uterine cervicitis in 20.4% of examined females. Changes were noted in vulva in 51.0% (40 to 10 papules and hyperemia) and the average of BCS was 3.15. On the basis of morphological aspects founded, 29 females with an average of BCS 2.7 and 01 with metritis were excluded and 07 (BCS-3, 5) inseminated immediately after the exam, with 61 included in the TAI program. These data support the conclusion that of all ovulations occurred, characterized by the presence of CL, most occurred in the right ovary (73.9%). The prevalence rate (51%) of vulvar aspects found, indicate a need for research of reproductive diseases in their flock. Conclusion: The BCS may impacts on the cyclicity and in the pregnancy rate of females included in the program.
