摘　　要：为发掘新疆地区新的绵羊地方品种资源,对诺维什羊主产区的自然生态条件、体型特征和生产性能进行了观察和测定分析。结果显示,诺维什羊对南疆地区自然生态条件适应性良好,具有较高的生长性能、屠宰性能、繁殖性能和产毛性能。诺维什羊成年公、母羊的体重分别达124.78 kg和103.25 kg,原毛产量分别为6.67 kg和4.57 kg,净毛率分别为49.25%和48.73%,羊毛长度均大于9 cm,体侧部、股部羊毛细度在20.31~21.64μm之间;育成公羊的屠宰率和胴体净肉率分别为52.65%和76.45%,育成母羊的屠宰率和胴体净肉率分别为52.28%和75.25%;初产母羊的平均产羔率和繁育率分别为128.53%和115.81%,经产母羊的平均产羔率和繁育率分别为158.04%和152.11%。In order to explore the new local sheep breed resources in Xinjiang,the natural ecological conditions,body shape characteristics and production performance of the main producing areas of Novish sheep were observed and analyzed in this study.The results showed that Novish sheep had good adaptability to the natural ecological conditions in southern Xinjiang,and had good growth performance,slaughter performance,reproductive performance and wool production performance.The body weight of adult male and female Novish sheep could reach 124.78 kg and 103.25 kg,respectively.The wool yields of adult male and female Novish sheep were 6.67 kg and 4.57 kg,respectively.The net wool rates of adult male and female Novish sheep were 49.25%and 48.73%,respectively.The wool length was greater than 9 cm,and the wool fineness of the side and thigh was 20.31-21.64μm.The dressing percentage and carcass net meat percentage of rams were 52.65%and 76.45%,respectively.The dressing percentage and carcass net meat percentage of ewes were 52.28%and 75.25%,respectively.The average lambing rate and breeding rate of primiparous ewes were 128.53%and 115.81%,respectively.The average lambing rate and breeding rate of multiparous ewes were 158.04%and 152.11%,respectively.
