USA HISTORY

Detailed explanation-1: -Oxen were chosen over horses to pull the wagons because of their strength, and because they were noted for being easier to work. They were generally docile, gentle, easily guided by a child, and strong enough to lug heavy wagons over rough terrain.

Detailed explanation-2: -Oxen were both more pliable and durable than horses or mules. It was easier to sustain oxen on the trail as they were more content to forage on the grasses of the Great Plains, whereas horses and mules required grains (such as oats) for optimum performance, an expensive and heavy substance to haul along the way.

Detailed explanation-3: -Teams of 10 to 12 horses or mules or six yoked oxen typically were used to pull one of these wagons, with mules and oxen generally preferred. Ideally, several more animals would be kept in reserve to replace those that became lame or worn-out along the route.

Detailed explanation-4: -Oxen were most often used for pulling this type of wagon. It required two yoke (pairs) of oxen. A spare yoke often trailed behind so that the livestock could be rotated and rested. For those who preferred mules, an equivalent number of harnessed mules could have been used in place of oxen.

Detailed explanation-5: -“Oxen pulled the timber and hauled the covered wagons west. They plowed the ground. They moved the freight.” Also, as the covered wagons moved west on the Oregon Trail, those pulled by oxen were more likely to reach their destinations than those pulled by horses.
