摘　　要：本文对中国美利奴羊(新疆军垦型)超细品系羔羊初生至15月龄的体重、体尺、羊毛生长逐月测定,并与成年羊进行比较。羔羊断奶前生长发育较快达到成年羊的70%,12月龄达到成年的90%,15月龄与成年羊差别很小。羊毛品质好,突出特点是羊毛纤维直径小。Weight ,body＇s size and longth of wools growing about Lambs of super- fine- wool breed of Chinese Merino Fine Sheep Xinjiang Army Reclamation Type were determined. And they were done once each month during the newborn first day to the 15th month and compared with grown-up sheep＇s. Growth and development of the lambs were fast before they were weaned. They were as same as 70 per cent of the grown - up sheep＇ s when the lambs were weaned, and they were as same as 90 per cent of the grown - up sheep＇ s at 12th month age of the lambs,and they were little disparities with the grown- up sheep＇s at 15th month age of the lambs. Quality of the lambs＇ wools was better, and the special characteristics of the wools was that the wool fibres＇ diameters were thin.
