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. This benefit may be particularly true for children. In most U.S. groceries, you should assume that you are always purchasing a sweet potato, even if the sign says yams.. 2  Over 1 million sweet potatoes are commercially grown in the U.S. each year, while commercial production of yams in the U.S. is rare.
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.
A good example is the Auroch, which was pretty much identical to modern oxen with the exception of its size: this dino-cow weighed about a ton, and one imagines that the males of the species were significantly more aggressive than modern bulls.ne little-known fact about the Auroch is that it actually comprised three separate subspecies. The most famous, Bos primigenius primigenius, was native to Eurasia, and is the animal depicted in the Lascaux cave paintings.
