06. Development of a system for early diagnosis of foot diseases in cows using acceleration sensors


 A method for collection and analysis of walking motions of cattle using acceleration sensors and Detrended Fluctuation Analysis (DFA) was developed. A walking score was determined by calculation of the similarity between a model limp pattern and the patterns from individual cattle. Scores for normal cows were less than 0.1; those for most cows with foot diseases were greater than 0.2. These data suggest that this system can be used for the diagnosis of foot disease.
