The factors affecting the oleic acid ratio in fatty acid of beef were researched in order to raise the certificate rate of Mitsuboshi, which is new brand name of Japanese Black cattle in Fukui and have oleic acid ratio in fatty acid higher than 55%. Oleic acid rates of cross section of the sixth and seventh libs of 1,811 Japanese Black cattle slaughtered during January 2014 and December 2016 were measured by simple measuring instrument. The influences of BMS, slaughter seasons, slaughter age and farmers on oleic acid were statistically analyzed. There was no significant difference in the oleic acid within BMSs; however the oleic acid ratio of higher BMS showed smaller Mitsuboshi rate (calculated by number of Mitsuboshi/total number of cattle* 100%). The slaughter seasons and age had no effect on the oleic ratio and Mitsuboshi rate, whereas the oleic acid ratio of heifers was significantly higher than that of steers (p < 0.05). The significant difference within farmers could be seen, and sex, bull and BMS could be considered as the factors affecting this difference.
