Production performance
It has the characteristics of early maturation, good meat production and hair production performance. Adult rams weigh 100-105 kg and ewes 45-65 kg; 4 months old lambs can reach 35-40 kg. The shearing amount is 10-12 kg for rams and 5-6 kg for ewes, and the net gross yield is 60%-65%. The lambing rate is 110%-130%.

In addition to pure breeding, it is used to improve Mongolian sheep, Tibetan sheep, etc., so that the improvement of the quality of local sheep and the breeding of new breeds of sheep have achieved obvious results.
As a patrilineal line, he participated in the breeding of northeast semi-fine wool sheep, Lingchuan semi-fine wool sheep, Guizhou semi-fine wool sheep, and Yunnan semi-fine wool sheep breeds. As a female hybrid with Lincoln ram, the offspring are significantly improved by the quality of the hair and the size of the meat.
