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).
