donkeys are about the size between a cow and a goat, mammoth donkeys on the other hand are as big as a horse
in the ice age where the glaciers are
the donkeys couldn't find the apples.
Donkeys come in 3 sizes, mini, standard and mammoth. Even a mammoth is usually only the size of a light horse. Donkeys also are more adapted to harsh environments than the horse and can get more "bang for his buck" out of his feed ration. So the short answer is a donkey eats less to maintain his weight that does a horse.
Mammoth donkeys must measure at least 54 inches at the wither (top of the shoulder) for jennets (females) and 56 inches at the wither for males (jack or gelding).
The smallest type of donkeys are called Miniatures, originally from Siciliy and Sardinia. The feral donkeys of the Old West can be called burros. The middle-sized animals common in Mexico and the USA are called Standard donkeys, for their height. The largest in the USA are Mammoth Jackstock. There are few true breeds of donkeys left, but those include the Andalucian, Majorcan, Maltese, and the Poitou donkey of France.
If you're going to ride a donkey, its best not to exceed a weight of 8 stone on their back at one time. But some donkeys can be big; Mammoth Donkeys can grow to 17hh and can carry the weight of a man.

The Mammoth was an Herbivore, eating tree roots, plants and any vegetation it could find.
You can get a mammoth's tusk by killing a mammoth or you can buy one from Lucan, the Riverwood Trader. If you want to get a mammoth's tusk without killing a mammoth or spending gold, you can find a few mammoth's tusks and snouts as well in Halted Stream Camp, but it in that location there will be a couple of bandits that you will have to kill.
About as long as my 12 inch or take a few.
