Abstract

This study aimed to evaluate kinematic patterns of forelimbs and hind limbs in clinically normal sheep from two different age groups walking at a constant velocity. Fourteen clinically healthy female sheep were divided into Group 1 - seven animals aged from 8 to 12 months, and Group 2 - seven animals aged above 5 years. Flexion and extension joint angles, and angular velocity were determined for the shoulder, elbow, carpal, hip, stifle, and tarsal joints. Within each group, no significant differences were observed between the right and left limbs in all kinematic variables. Significant differences were observed in the following kinematic parameters between G1 and G2: minimum angle (G1G2), maximum angular velocity (G1>G2), minimum angular velocity (G1>G2) of the carpus; angular displacement (G1>G2), minimum angular velocity (G1>G2) of the shoulder; minimum angle (G1>G2), angular displacement (G1G2 of the hip. The lengths of both forelimbs and hind limbs differed between groups (G1
