History
editIn 1942, then-Council of Ministers (Cabinet) of Mongolia issued a resolution to develop domestic fine and semi-fine wool breeds to meet the increased national manufacturing demand. Selection and breeding works started in 1942 with successive cross-breeding of Soviet Tsigai and Altay rams.
The first certificate confirming the breed was issued on January 1, 1961, by then-Standards and Measurements Authority of People's Republic of Mongolia to the breed's developer, researcher and veterinarian T. Ayurzana (1910-1972).[1][2]

On average and at maturity, rams produce 5,6 kg and ewes produce 3,7 kg of semi-fine wool. Average wool length is 8 cm, the average diameter of the Orkhon fiber is 25-31 microns.
Approximately 1.15 lambs per litter. Age at first breeding is 18 months, average liveweight at birth is 4 kg for males and 3.6 kg for females.
This is hardy sheep adapted for Mongolian harsh climate, grazed on pastures all year round.
