摘要/Abstract

摘要： 辽宁绒山羊的产绒性能与其皮肤毛囊结构是密切相关的。通过组织切片技术观察辽宁绒山羊皮肤毛囊结构，并对获得的数据进行最小二乘均数分析，研究了辽宁绒山羊羔羊不同月龄，不同季节毛囊密度和S/P值的变化及出生类型，母羊年龄对毛囊性状影响。结果表明，辽宁绒山羊的毛囊群主要是由3个初级毛囊和若干个次级毛囊组成的三毛群，三毛群占毛囊群总数的75%左右。次级毛囊呈楔形群排列在中心初级毛囊和外周初级毛囊中间，随着羔羊月龄的增长，毛囊密度逐渐下降，S/P值逐渐上升，S/P在6月龄达到最大值。成年羊初级毛囊密度季节间变化不大，次级毛囊密度和S/P值表现出明显的季节变化，4月份次级毛囊密度和S/P值最小，9月份次级毛囊密度和S/P值最大。

Abstract: Differences of follicle density and S/P among different months of age in young goats and among seasons of year in adult goat and effects of age，birth type and mother’s age on follicle traits were studied in this paper. Follicle group was consisted of three primaries and a varying number of secondaries with a wedge-shaped group among central and lateral primaries, Rate of tri-group was about 75%.With increase of age，S/P increased with a maximum at 6 months of age and follicle density decreased.There was no obvious changes among seasons in primary density of adult goats.But there were significant differences among seasons in secondary density and S/P of adult goat with a maximum at September and a minimum at April. 
