First, it is dark, meaning that it is not in the form of stars and planets that we see. Observations show that there is far too little visible matter in the Universe to make up the 27% required by the observations. Second, it is not in the form of dark clouds of normal matter, matter made up of particles called baryons.
Livestock[edit] The raising of livestock, sheep (the traditional mainstay for generations of Icelandic farmers) and cattle (the latter grew rapidly in the 20th century), is the main occupation, but pigs and poultry are also reared; Iceland is self-sufficient in the production of meat, dairy products and eggs.
Origin. The breed of Red Angus originally began in Europe, and was introduced to England and Scotland during raids. However, in Europe at this time, there was need for a heavier cow to be used for pulling draughts. English Longhorns, a large breed of cattle and red in colour were brought in and bred with the black polled breeds native to Scotland. This resulted in the red colouration of the Aberdeen Angus. After the union of England and Scotland in 1707 a higher demand in beef cattle arose for farmers. In 1795, in the midst of the French Revolution the beef and grain prices went up higher still.
