Mongolians call meat food "Ulan Yide", which means red food. Meat food is the main food for raising Mongolians. According to Black Tatar, Mongolian meat products mainly come from hunting products and livestock. Hunting animals include rabbits, deer, antelopes and so on. The usual food is mainly livestock, mainly sheep, followed by cattle, not large banquets, and horses are generally not killed, because now they think horses are more noble animals. "Suiyuan Tongzhi Draft" said: "Its custom is to avoid eating horse meat. In the early years, everyone changed jobs and made meritorious deeds, so they used their strength not to eat meat. " . Of course, this is also related to the traditional Mongolian concept of loving horses. This eating habit lasted for nearly a thousand years, which not only formed the unique custom of this nation, but also had a certain influence on other hunting nations. In the meat structure of Mongols, eating small animals is the main thing, and sheep is the main thing, because sheep are the main livestock, and the rest are obtained by hunting. Mongolians believe that heat-eating animals are beneficial to human health, because cows and horses are relatively large animals, which are not as convenient to slaughter as sheep and are responsible for transportation, so horses are usually slaughtered at the time of sacrifice. Mutton is the favorite meat of herders. In the long-term life, herders have accumulated rich life experience and made a series of mutton delicacies such as roast whole sheep and braised pork.
