| Abstract: | Qianhua Mutton Merino(tentative name) is a new sheep breed in breeding, the research on the characteristics of its germplasm will provide theoretical basis and technical reference for further breeding. Therefore, the natural ecological condition, variety appearance and production performance index of the area were observed and analyzed. The results showed that: Qianhua Mutton Merino had a well adaptability to the transition zone between cropping area and nomadic area in northeast in China; and the new sheep breed also had good growth performance, meat production performance, reproductive performance and wool production performance; The weight of the male and female of the breed were 124.78 kg and 103.25 kg, the wool yield and net wool rate were 6.68 kg and 49.15%, 4.67 kg and 48.83%, respectively. The length of the wool of the adult sheep was more than 9 cm; the diameter of wool fiber in the side of the body was between 20.32-21.45 μm. The slaughter rate and carcass meat percentage of male and female were 51.65%, 75.45%, 51.28%, 74.25%, respectively. The lambing rates of primiparous and multiparous ewes were 125.23% and 150.21%. The survival rates of lamb were 93.12% and 95.26%, respectively. |
