  • Thermally sensed, automatic cow body condition scoring
    Halachmi, I. ...
    The feasibility of including a body shape measure methods for automatic monitoring of body reserves of cattle was evaluated. The hypothesis tested was that the body shape of a fatter cow is rounder ... than that of a thin cow and, therefore, may better fit a parabolic shape. The hooks and the tailhead nadirs of a thin cow diverged from the parabolic shape. An image-processing model calculates a parameter to assess body shape. The model was implemented and its outputs were validated against ultrasonic and thermal camera measurements of the thickness of fat and muscle layers, and manual body condition scoring (BCS) of 186 Holstein-Friesian cows. The thermal camera overcomes some of the drawbacks of a regular camera. The correlation between thermal camera's measurements and fat and muscle thickness was 0.47. Mean body condition scoring were 2.18, 2.15, 2.23, with no significant difference found across the assessment method. Further research is needed in order to achieve fully automatic, accurate, body condition scoring.
