What happens if a male horse and a female donkey mate?

When a male horse and a female donkey mate, they produce an offspring called a hinny. Hinnies are somewhat smaller than mules, which are the product of breeding between a female horse and a male donkey.

Hinnies are less common than mules, but like mules, they are hardier animals than horses, with a strong resistance to disease and parasites. Hinnies tend to eat a broader range of plants than mules do, and their gait is more steady and plodding.

Hybrids such as hinnies are generally sterile. However, two female hinnies in the United States have bred with other equines and produced foals. Depending on the species of the male parent, these offspring may be called hules, jules or donkules.
