Prediction of ham weight with the autofom in Korea

The Autofom is a equipment for predicting the amount of pig carcasses meat using the 16 ultrasonic sensors to measure in real time and it was established in Dodram LPC in Gyeonggi Province of Korea for the first time. This study was carried out to validate the reliability of Autofom statistically and to establish guideline for developing a analytic formula through comparing the measurement between Autofom and dissection. The ham parts of sixty-six pig carcasses were measured with Autofom and by two experimental performers. The weight means and standard deviations of ham parts including bone by measurements with Autofom and dissection were 10.69±0.81kg and 10.77±0.94kg , respectively a strong positive correlation (P<0.01) was identified, with a coefficient of determination ( R² ) of 0.82. The weight means and standard deviations of lean ham parts by measurements with Autofom and dissection were 7.41±0 .58kg and 7.42±0.89kg , respectively a strong positive correlation (P<0.01) was identified, with a coefficient of determination ( R² ) of 0.72. The root mean square errors of two groups were 0.40 and 0.50, respectively.
