The Mongolian pastoral nomads relied on their animals for survival and moved their habitat several times a year in search of water and grass for their herds. Their lifestyle was precarious, as their constant migrations prevented them from transporting reserves of food or other necessities. Rarely having the luxury of surpluses to tide them through difficult times, they were extremely vulnerable to the elements. Heavy snows, ice, and droughts (judging from contemporary times, droughts afflicted Mongolia about twice a decade) jeopardized their flocks and herds and heightened their sense of fragility. The spread of disease among the livestock could also spell disaster. Herders hunted and farmed to a limited extent but were dependent on trade with China in times of crisis.
The most numerous and valuable of the Mongols' principal animals, sheep provided food, clothing, and shelter for Mongol families. Boiled mutton was an integral part of the Mongol diet, and wool and animal skins were the materials from which the Mongols fashioned their garments, as well as their homes. Wool was pressed into felt and then either made into clothing, rugs, and blankets or used for the outer covering of the
gers [or tents].
Dried sheep dung was collected and used for fuel. Though the Mongols used wood and currently also use coal as fuel sources, animal dung was often the most readily available source. Women, and secondarily children, were responsible for gathering the dung.
Survival of young sheep (and other animals) was vital to maintaining the pastoral-nomadic way of life, and a significant responsibility for Mongol women was to coax the ewes to nurse their young.
Goats were not as pervasive as sheep in the Mongol flocks, but the Mongols consumed goat meat, milk, and cheese. The poor wore goat skins; and in more modern times, goats have become valuable as the source for cashmere.
Because goats were not as tough and needed more care than sheep, the Mongols kept fewer goats. In addition, because goats consume the grass to the root when they graze, they devastate the grasslands, resulting in desertification.
Mongols in traditional times therefore limited the number of goats in their flocks. Modern demand for cashmere caused many herders in the 1990s to increase their numbers of goats, potentially undermining the traditional ecological balance.
The reproduction of sheep and goats is essential for the survival of Mongol pastoralism. The animals are culled annually for food, hide, and skin, and many do not survive the harsh winters. Replenishment of the herds and flocks, therefore, is vital. But encouraging successful procreation and survival of the young requires tremendous skill and knowledge.
Another threat to the survival of the sheep and goats are wolves. They generally attacked the young but were also known to threaten adult animals. Herders kept and trained fierce dogs to protect the herds from such predators. In addition, the Mongols periodically went on hunts to cull the wolf population.
Yaks and oxen require excellent grazing grounds and cannot endure well in the deserts and other marginal areas. They are found primarily in the steppelands, and thus there are fewer of them than sheep or goats.
Yaks offer meat and milk, and the Mongols often use yak and ox carts to transport their belongings as they migrate from one region to another.
The Bactrian or two-humped camel permits the Mongols to transport heavy loads through the desert and other inhospitable terrain. The camel is invaluable not only for transporting the folded
gers and other household furnishings when the Mongols move to new pastureland, but also to carry goods designed for trade.
A camel could endure the heat of the Gobi desert, could drink enormous quantities of water and then continue for days without liquid, required less pasture than other pack animals, and could extract food from the scruffiest shrubs or blades of grass — all ideal qualities for the daunting desert terrain of southern Mongolia.
In addition to the camel's importance for transport, the Mongols valued the animal's wool, drank its milk (which can also be made into cheese), and ate its meat. No wonder then that "in the Mongol epoch the camel enjoyed the highest esteem he was attain in the Chinese lands" [in "The Camel in China Down to the Mongol Invasion" by Edward Schafer,
Sinologica, 2 (1950), p. 190].
Horses offered mobility to the Mongols, permitting them to roam the steppes in search of pasture for their flocks, as well as to round up other horses that have been allowed to graze freely faraway from an encampment.
Riders gathering the horses together were equipped with a pole at the end of which was a special lasso. Children, who became skilled riders at an early age, assumed this responsibility on occasion.
In traditional times horses gave the Mongols the decided tactical advantage of mobility in conflicts against sedentary civilizations. They could, for example, initiate a hit-and-run raid on a Chinese village, fleeing to the steppelands and thus evading the less mobile Chinese forces.
