The study of the ovarian morphometry is directly related to its applications to analyze and interpret the discoveries in the gynecological exams of cows.For this work, 114 pairs of ovaries were gathered in refrigerator, classified starting from the width, thick, long, volume, follicle diameter, diameter andarea of the luteal body. A significant difference was observed in the width (1,95cm and 1,83cm) and the volume (7,26 mL and 6,23 mL) of left andright ovaries, respectively. As for the size and the volume of the follicles, the diameter and the area of the luteal bodies, there was not an outstanding difference. At the sides it was a positive correlation (p < 0,01) between thevolume of the left ovary and the area of the luteal body. The presence of follicles with equal or higher diameter than 9 mm, the solid and protrusive type of luteal body present in 43,39% of the 53 ovaries, prevailed over the concave type. 26,20% of the 84 ovaries with luteal bodies where extrapolated type. The study concludes that the presence of luteal body, even in zebucows, it can lead to diagnostic flaws during the exam of rectal palpation to estimate the ovarian activity.
