Succeeding to the Bull. Fac.Agr.Yamaguti Univ. N0.7､1956 which the writer had already published on tbe Traction Theory of Domestic Animals, he calculated the variation of the weight to the anterior and posterior extremities by the work of traction and the limit point of the maximum pulling force according to the formula he discovered, and the results obtained are as follows: 1.By means of inclining its posture forward, the burden of the body weight to the anterior extremities is increased by the rate of＋x and that to the posterior extremities decreased by the rate of -y. 0n the other hand, as the tractive force works on the animal body, the burden of the weight to the anterior extremities decreased by the rate of -x and that to the posterior extremities is increased by the rate of ＋y･ ・・・
