Because of the elective use of Caesarean Section (CS), the Belgian Blue (BB) breed is being criticized by animal health organizations in Europe and it also has economical consequences. Within the selection for the reduction of CS, the increase of pelvic dimensions plays a crucial role. Correct information about the pelvic canal is a very important condition to perform this selection. Measurements of the pelvic canal in living animals can be performed by using a Rice pelvimeter. The present paper describes a study of the repeatability between two different technicians and within one technician of pelvic measurements in double muscled BB cows using a Rice pelvimeter. Additionally, changes within the pelvic dimensions at parturition were examined by measurements at three different points around calving (one month before, within 24 hours and two weeks after parturition). No significant differences were found for the pelvic height between the two technicians. The variation coefficient of the measurements of the second technician proved to be smaller but not significantly different from technician 1, for pelvic width as well as for pelvic height. Only the pelvic height measured at parturition significantly differed (0.48 cm) from the measurements taken one month before calving (P < 0.05). Based on these results we can decide that the measurements taken by the Rice pelvimeter are repeatable within one technician and between two different technicians. Finally, parturition can have an effect on the pelvic measurements.
