We studied on phases of the curve of pulse rate after the beginning of a certain work, with special emphasis on the difference observed when the animal was imposed with a overloaded work with which it seemed to have tired before the work, and when it took a rest before the work. Four adult goats were used as experimental animals. We used the same methods as were described in the previous report (IV) of our series of studies, by which the work was imposed on the goat and by which its pulse rate was measured. From the results of this study we knew that there was a following difference in the relation between three values, namely, 2-min. value (a), 4-min. value (b) and 6-min. value (c) of the pulse rate after the beginning of a certain work, regardless of whether it had been imposed with a overloaded work before the work or not. When the goat was imposed with a overloadedwork before a certain work: a_??_b+c/2When the goat took a rest before a certain work: a>b+c/2Furthermore, we used 4 goats and imposed a certain heavy work on them every day for the sake of training. In this case, the relation among the three values mentioned above was changed from a_??_ b+c/2 to a>b+c/2 at 3 days after the beginning of training. We believe that this change was dependent upon the effect of training in the goat. From the results described above, we suggest that the value of pulse rate after the beginning of a certain work, especially the 2-min., 4-min. and 6-min. value, may be used as an index of the degree of fatigue and as a tester for pulling performance in the farm animal.
