Abstract
GOMEZ-L, Víctor et al. Methodology for ultrasound evaluation of uterine biometry in the bovine female. rev. colombiana cienc. anim. Recia [online]. 2017, vol.9, n.2, pp.122-128. ISSN 2027-4297. https://doi.org/10.24188/recia.v9.n2.2017.549.
The objective was to evaluate a methodology to measure the endometrial thickness and diameter of the uterine horns. For which, the uterine horns were divided into three regions. From the intercornual septum to the beginning the greater curvature, it was considered the first region. From the greatest curvature to apex of the second horn region, and free end of the horn the third region. The endometrial thickness and the diameter of the horns were measured in animals in vivo and in the genital organs of the same post mortem. Five sexually mature cows of the Holstein breed, raised in Losing-House management, were used. The quantitative data were analyzed by ANOVA and the means compared by Tukey’s tests or by non-parametric analysis comparing the means by the Kruskall Wallis test. The mean values did not present differences for the characteristics evaluated in the animal in vivo compared to those obtained post mortem (P> 0.05). In the measurements obtained, the third region showed similar mean values for diameter (21.0 ± 2.6 mm - 22.9 ± 2.8 mm) and endometrial thickness of both horns (10.4 ± 4.9 mm - 10, 8 ± 5.2 mm). Likewise, the values obtained for thickness and diameter of both uterine horns of the third region was similar to the values obtained in the second and first regions. However, the values of the second region differed from those obtained in the first region (P <0.05). Thus, obtaining ultrasound images in cross-sections and measuring uterine biometrics from bifurcation to greater curvature, is efficient and representative of the endometrial thickness and diameter of the uterine horns as a whole.
