Abstract

Dystocia causes adverse effects to both the dam and calf which results in a significant economic impact to the farmer. Small pelvic area in dams is an important contributor to dystocia causing a physical incompatibility with the fetus or feto-pelvic disproportion. The relationship between intrapelvic measurements and external morphometric measurements was studied in 50 Friesian cross cattle to determine the usage of external measurements as predictors for intrapelvic parameters. External morphometric parameters taken were thoracic circumference, abdominal circumference, distance between tuber coxae and distance between tuber ischii. A Rice pelvimeter was used to measure the intrapelvic parameters of pelvic height (PH, cm) and pelvic width (PW, cm). The pelvic area (PA, cm2) was calculated using the formula PA = PH × PW. Pearson’s correlation (SPSS 22) showed that all external morphometric measurements were correlated with intrapelvic measurements (0.43 < r < 0.60, P < 0.05). Regression analyses showed that the internal pelvic parameters can be predicted from body weight and external morphometric measurements. In conclusion, there was an association between the intrapelvic measurements and the external morphometry and by using the models derived, the intrapelvic measurements can be predicted from the external morphometry.
