The aim of this research was to consider factors affect amounts of inosinic acid and glutamic acid in Japanese Black cattle. Sirloins of 262 cattle fed in Fukui were sampled to analyze amounts of inosinic acid and glutamic acid. In consequence, with respect to inosinic acid, heifers showed higher than steers (P < 0.05), and cattle which sire line was "Fujiyoshi" showed higher than that of "Tajima" and "Kedaka" (P < 0.05). No significant difference could be seen within sex and sire line of carcasses about glutamic acid. Both of inosinic acid and glutamic acid had no correlations with slaughter age, weights of carcasses, oleic acid ratio and crude fat contents. However, regarding slaughter age, the amounts of inosinic acid of cattle slaughtered at age 24 and 25 months were the highest, decreasing until age over 29 month, and there was an increase in glutamic acid from 24 to 26 month and a decrease after that till 28 month. Overall, it could be said that heifer which sire line is "Fujiyoshi" and slaughtered at age between 24 and 26 month might contain higher inosinic acid and glutamic acid in its carcass.
