The influences of starting fattening Japanese Black earlier or allowing them to exercise in paddock next to the barn on meat quality were examined to improve the contents of inosinic acid and glutamic acid in meat. 3 groups of heifer were set in this study; heifers in Group1 were started fattening two months earlier, that in Group2 were allowed more exercise in paddock and the Group3 was control group. The averages of the weights and the daily gain of heifer of each group at 25 months of age were 659kg and 0.84kg/day, 650kg and 0.80kg/day, and 659kg and 0.83kg/day respectively, and there was no significant difference within the groups. In terms of intake of feed, the highest was of the Group1 during 11 and 14 months of age since they were fattened earlier than others, however the other two groups reached to about 8kg/day which was same level of intake as the Group1 after 15 months of age i.e. there was no difference in intake of feed after all groups started fattening. The moved distance of heifer in the Group2 was twice as long as that in the Group3. No abnormality could be seen in the result of blood test.
