Study on the Traction Theory of Domestic Animals

The writer has studied the dynamic effect given to the pulling force of animals by the work of traction, and what kind of traction method will be the best in order to let the animal exert full pulling capacity. The results obtained are as follows: 1.The burden of body-weight to the anterior extremities is diminished and that to the posterior extremities is increased by the work of traction. The diminishing rate of the burden of body-weight to the anterior extremities is maximum when the traction line is horizontal, and it becomes smaller and smaller as the angle between the dragrope and the horizontal plane changes or increases. When the dragrope coincides with the position of the hoofs of the posterior extremities､the work of traction does not add any load to the anterior extremities at all.・・・
