Abstract

We determined the weight, volume and center of gravity (CG) of 20 frozen body segments using three Thoroughbred horses. Segment weight and volume to whole body weight and volume were 4.4 and 4.1 (%) for the head, 7.0 and 6.5 neck, 59.5 and 63.0 torso, 9.2 and 8.6 scapulabrachia, 1.8 and 1.6 antebrachia, 0.5 and 0.4 metacarpi, 0.5 and 0.4 digiti, 13.8 and 12.7 thigh, 2.0 and 1.6 crura, 0.8 and 0.6 metatarsi, 0.6 and 0.4 digiti, and 0.1 and 0.1 for the tail. Segmental body density was more than 1 g/m3 except 0.90 g/cm3 for the torso. Total body density calculated from total weight and volume was 0.95 g/cm3. The location of CG for each body segment was presented on the reference line by percentage of distance from location of segment CG to proximal end which was divided by the segment length.
