Oxen trample teff, a small-grained cereal, to remove the grain in a typical rural setting outside Shashemene. Depending on the availability of animals, a farmer may use ponies, donkeys or oxen for this purpose.Teff is grown extensively in Ethiopia and is used to make injera, a fermented, bread-type pancake, which is the country's national dish. Teff stands as an example of Ethiopia's early success as a centre for plant domestication.
