Ujimqin sheep are native to the grasslands of Uzumi, located in the eastern part of the Xilin Gol League within the Inner Mongolia Autonomous Region. These sheep are primarily found in both East Ujimqin Banner and West Ujimqin Banner, as well as parts of Xilinhot City and Abaga Banner. Known as a fat-tailed sheep breed, Ujimqin sheep are characterized by their large body size, prominent fat tail, and high lambing rates. This breed has been gradually developed over many years through natural and artificial selection, adapting to the specific climate and traditional grazing practices of the region.
**Physical Characteristics**
Ujimqin sheep are known for their strong and robust build. They have a medium-sized head with a slightly wide forehead and a slightly raised nose. Most rams are hornless, while a few may have small horns; ewes are typically hornless. Their chest is deep, and their ribs are well-spread, with the chest reaching nearly half the height of the body. The back is broad and flat, and the hindquarters are well-developed, giving them a balanced and muscular structure. Their legs are strong, and they have a short fat tail. Coat colors vary, with approximately 6.2% black, 10% white, and 11% of other colors.
**Production Performance**
Ujimqin sheep are highly adaptable and thrive on grazing throughout the year. They rarely require supplemental feeding, except during heavy snowfall when forage becomes limited. These sheep grow rapidly, with male lambs weighing around 29.5 kg and females about 24.9 kg at 2.5 to 3 months old. By six months, males reach an average of 40 kg, and females reach 36 kg. Adult rams weigh between 60 to 70 kg, while adult ewes range from 56 to 62 kg. The average carcass weight is 17.9 kg, with a slaughter rate of 50%, and the net meat yield is about 11.8 kg, giving a net meat rate of 33%. The meat is lean, rich in minerals such as calcium, iron, and phosphorus, and has good marbling due to sufficient fat accumulation between muscle fibers. The lambing rate is approximately 100%.
Ujimqin sheep are well-suited for continuous grazing and are known for their fast growth, efficient fat deposition, high meat yield, and early sexual maturity. They are ideal for grazing, fattening, or planned lamb production. Additionally, they serve as excellent recipients for embryo transfer programs, producing offspring that are disease-resistant and highly adaptable to various environments.
