The usage of pelvimetry to predict dystocia in cattle

Pelvimetry is the measurement of the dimensions of the pelvis, measured internally or externally, and is typically conducted with the aid of a pelvimeter. Intrapelvic dimensions, namely the intrapelvic height and width, are used to calculate pelvic are a which has a moderate to high degree of heritability. Pelvic area measurements are associated with calving difficulty and have been used by producers to select for heifers to be included in their breeding herd.

It could be proved that the different diagnostic imaging as CT and ultrasonography contribute greatly in veterinary practice as the data obtained from diagnostic imaging can be used as a diagnostic tool and baseline data for educational,clinical and research purposes.

It is concluded that pelvimetry is a useful culling tool to aid in the management of dystocia in yearling heifers and that adjustment of PA to median BW or LBW within age group improves its accuracy and avoids the undesirable side effects.

Three methods for predicting difficult births were tested on 4,140 yearling heifers measured before breeding and(or) at pregnancy check approximately 6 mo later and found them to be not a useful on-farm method for Predicting difficult births in first-calf, 2-yr-old heIFers.
