A comprehensive ultrasonographic examination of the normal pelvic girdle in 24 mature crossbred Jersey cows, aged 3 to 8 years, calved once and above were taken for this present study. The ultrasonographic evaluation focused on various pelvic girdle components, including the coxofemoral joint and its anterior and posterior capsules, both externally and internally. Key findings include the observation of pelvic tuberosities (sacral, coxal, and ischial) as convex arches with surface irregularities. The bony external surfaces of the iliac wing, body, and ischium appeared as thin, hyperechoic concave arches, while the internal surfaces of the ischium’s tabula and the medial aspect of the acetabulum were seen as thin, hyperechoic convex arches. Pelvic articulations, including the hip joint, were visualized as anechoic bands bordered by hyperechoic arches. The mean distance from sacral tubers to the skin is 0.721 ± 0.011 cm. The mean thickness of the dorsal aspect of the dorsal sacroiliac ligament-thoracolumbar fascia fusion is 3.4167 ± 0.061 cm, while the mean thickness of the dorsal sacroiliac ligament is 2.300 ± 0.0326 cm. Additionally, the mean distance from the skin surface to the joint measures 65.732 ± 2.585 cm. The mean thickness of the articular cartilage is reported as 2.35 ± 0.042 cm, and the mean distance between the sacral tubers and the first sacral spinous process is 1.947 ± 0.084 cm. These results provide a detailed ultrasonographic description of the pelvic girdle in mature cows and serve as a valuable guide for pelvic examinations.
