What's New and Beneficial about Sweet Potatoes. 1  Orange-fleshed sweet potatoes may be one of nature's unsurpassed sources of beta-carotene. 2  Several recent studies have shown the superior ability of sweet potatoes to raise our blood levels of vitamin A.

Oxen used in farms for plowing. An ox (plural oxen), also known as a bullock in Australia and India, is a bovine trained as a draft animal. Oxen are commonly castrated adult male cattle; castration makes the animals easier to control. Cows (adult females) or bulls (intact males) may also be used in some areas.
Ox vs Cow. A cow and an ox are members of the Bovinae subfamily. In terms of physiology, cows and oxen do not have significant differences. But humans differentiate cows and oxen according to their specific use in the farm. So here are some unique differences between a cow and an ox. A cow is a female. To be called as such, it should be approximately 4 years old and has given birth to at least one calf. Its male counterpart is called a bull. An ox, on the other hand, is a castrated mature bull. So gender can be said as the primary difference between an ox and a cow. A cow is raised as a livestock for its meat. It is also a dairy animal which is a source of milk and other dairy products like butter and cheese. Meanwhile, the ox is a draft animal.
