A motion measurement system for measuring changes in the motion of the body of an animal. An animal instrumentation assembly of the motion measurement system has a plurality of motion measurement sensors that are operatively coupled to a selected portion of the body of an animal. The motion measurement sensors produce measurement signals indicative of the change in the motion of the animal, and these measurement signals are transmitted to a processor of the animal instrumentation assembly. A wireless transmitter transmits wireless signals corresponding to the measurement signals, and these wireless signals are received by a computing assembly. A processor of the computing assembly converts the wireless signals into corresponding animal data elements, which are stored in a memory. The computing assembly can be positioned in wireless communication with remote computing devices to permit distribution of the animal data elements.
