摘　　要：为比较中国美利奴超细型羊单羔与双羔的生长规律和生产性能的差异,本研究从中国美利奴超细型羊核心群随机选出50只单羔和50只双羔,在初生、断奶、周岁期间对体重、体高、体长、胸围、管围等五个生长指标和周岁的产毛指标进行测量及分析。结果表明:单羔初生体重较双羔重0.34 kg(P<0.05),体高较双羔高5.12 cm(P<0.01),单、双羔间体长、胸围、管围差异不显著;断奶和周岁时单羔和双羔的体尺、体重及周岁时产毛性能产业也不显著(P>0.05)。In order to compare the growth and production performance differences between monotocous and biparous lambs of Chinese Merino superfine sheep,50 monotocous lambs and 50 biparous lambs were randomly selected from the core sheep group.Five growth indexes including body weight,body height,body length,chest circumference,tube circumference and wool production index of one year old were measured and analyzed during the period of birth,weaning and one year old.The results showed that the birth weight of monotocous lambs was 0.34 kg heavier than that of biparous lambs(P<0.05),and the body height of monotocous lambs was 5.12 cm higher than that of double lambs(P<0.01).There was no significant difference in body length,chest circumference and tube circumference between monotocous and biparous lambs.The differences of body size,weight and wool production performance of monotocous and biparous lambs at weaning and one year old were not significant(P>0.05).
