This study aimed to reveal the probable anatomic differences of the T13–L1 or L1–L2 vertebrae in Simmental and Brown Swiss cattle during surgeries, such as subarachnoid anesthesia and cerebrospinal fluid aspiration, and thus determine a reference value. This study was conducted in 30 cows, of which 15 were Brown Swiss cattle and 15 were Simmental, aged 5–6 years, and having a live weight of 400–450 kg. The region from the T13–L1 vertebrae to the sacrum was taken from each animal and divided into 2 equal parts throughout the long axis. The distance between the spinous processes of the T13–L1 and L1–L2 vertebrae, spinous processes length of the T13 and L1 vertebrae, sagittal length of interarcuate spaces between the T13–L1 and L1–L2 vertebrae, and vertical length of vertebral canals of the T13 and L1 vertebrae were measured using an electronic digital caliper. Statistical results showed that although there was no significant difference within the groups (p > .05), there was a significant difference between the groups in terms of the sagittal length of interarcuate space between the T13–L1 vertebra (p < .05). We believe that this result is because of the anatomical and genetic differences between the 2 cattle breeds.
