What's the difference between a horse and a donkey? What are the similarities between a horse and a cow?

Cattle are long-horned artiodactyls, while horses and donkeys are ungulates without horns on their heads. Horses are large herbivorous mammals. It was domesticated by humans in prehistoric times and used as a pack animal, a tractor and a vehicle. It is different from other existing horses and equines in that its tail hair and mane are long, there is a callus under the hock joint of its hind legs, and there are some unfixed features (such as larger body, larger hoof, slightly arched neck, smaller head and shorter ears).

The image of a donkey is like a horse, mostly taupe and not dignified. It has a big head and long ears, a slightly narrow chest, thin limbs and a short trunk, so its height and length are roughly the same, and it is square. Thin neck skin, small and firm hooves, strong physique and strong resistance. Donkeys are strong, resistant to extensive farming, not easy to get sick, and have the advantages of docile temperament, diligence and obedience.

In ancient China, cattle were the general names of different species and genera of cattle.

All three animals eat grass and are domestic animals.
