Ujumqin sheep are a larger version of the Mongolian breed, are
found in Inner Mongolia, China. They have a fat tail 28 cm (11.2 in) long by 36
cm (14.4 in) wide in the male, and 22 cm long by 28 cm (8.8 in) wide in the
female. When dressed, the tail fat weighs 2 kg (4.4 lbs) or more. Ujumqin sheep
were developed due to the sharp seasonal contrast in plant growth in the
pastoral areas.
The sheep tend to deposit a large amount of fat in the body
in order to meet nutritional demands during winter and spring. They are adapted
to the unfavorable local environmental conditions of the North and Northwest
Pastoral Grasslands. Their Wool is coarse and production is low, with an annual
grease fleece weight of only about 1 kg (2.2 lbs).
