摘要  本研究对内蒙古白绒山羊早期生长性状和抓绒性状的非遗传因素进行分析,结果表明,出生年份、场、性别、出生类型、母亲年龄对出生重、断乳重以及日增重均有极显著的影响(p<0.01)。断乳时期对断乳重和日增重也有显著的影响(p<0.05),出生月份对断乳重有极显著影响(p<0.01),周岁重受测定年份、场和性别的极显著影响(p<0.01)。出生类型对所有抓绒性状影响都不显著(p>0.05),场和年龄对所有抓绒性状都影响极为显著(p<0.01),测定年份对绒长度和毛长影响不显著(p>0.05),而对其他性状影响均显著,性别对绒细度影响不显著(p>0.05),对其他性状影响均显著。有些性状还受到其他非遗传因素互作效应的影响。 In this study, analysed the non-genetic factors influencing early growth traits and cashmere traits of the Inner Mongolian White Cashmere Goats. The results indicated that the extremely significant influences of birth year, flock, sex, birth type and age of dam on birth weight, wean weight and daily gain were found(p<0.01); and lactation stage had apparent influences on wean weight and daily gain(p<0.05); and the extremely significant influences of birth month on wean weight was occurred(p<0.01); yearly weight only was extremely significantly influenced by the year of mensurated,flock and sex(p<0.01).flock and age had extremely significant influences on all cashmere traits (p<0.01)while birth type had no influence(p>0.05); and the mensurating year had extremely significant influences on other cashmere traits excluding cashmere length and wool length(p>0.05); and sex apparently influenced other traits except fineness of cashmere fibre; in addition, all cashmere traits were extremely significantly or significantly influenced by interact effect between non-genetic factors .
