摘 要:
试验测定周岁陇东绒山羊的主要经济性状，采用父系半同胞相关法估测了遗传力。结果表明，陇东绒山羊周岁母羊产绒量、体重、体高、体长、胸围、管围、羊绒直径、绒层高度、羊绒伸直长度的遗传力分别为0．4129、0．3871、0．3732、0．3128、0．3468、0．2873、0．4013、0．3916、0．3908，为陇东绒山羊的科研育种提供了一定的科学依据。[著者文摘]

Abstract:
The experiment measured the main economic traits of Longdong one-year-old female Cashmere goats and estimated their heritability by 4 different regression method. The result showed that the heritabilities of Cashmere yield, body weight, body height, chest girth, cannon circumference, Cashmere diameter, Cashmere layer height and straightening length of Cashmere are 0. 4129,0. 3871,0. 3732, 0. 3128,0. 3468,0. 2873,0. 4013,0. 3916,0. 3908, Providing a scientific reference for breeding and improvement of Longdong cashmere goat.[著者文摘]
