画像解析による牛ロース芯内脂肪面積割合からの粗脂肪含量推定法 Prediction of the Crude Fat Contents in Rib-Eye Muscle of Beef Using the Fat Area Ratio Calculated by Computer Image Analysis
The purpose of this study was to examine the accuracy of estimation of crude fat contents in rib-eye muscle determined by chemical analysis from the fat area ratio calculated by computer image analysis (CIA). The materials used were 64 rib-eye images of 35 Japanese Black, 6 Angus and 23 F1 breed cattle. The fat area ratio was calculated using a software developed by the authors. The regression equation of the crude fat contents (Y) on the fat area ratio (X) calculated by CIA was Y=0.741 X-2.22 (r2=0.91, P<0.01). The difference between the estimated crude fat percentage using the regression equation and the actual one was -2.54-2.80%. No significant effect of the breed on the regression coefficient was found (P>0.10).
