The aim of this study was to compare the quality characteristics and mineral content of the fiber from male and female cashmere goats raised under different management systems. Male and female Raeini cashmere goats (<1.5 years of age, n = 48) were selected from flocks raised at a government breeding station or raised commercially under either rural or nomadic conditions. The staple length, cashmere fiber diameter, coefficient of variation for fiber diameter, percentage of cashmere in a fleece, percentage of guard hair in a fleece and cashmere tenacity averaged 4.6 ±0.1 cm, 18.0 ±0.1 μm, 20.9 ± 0.4%, 66.1 ± 1.5%, 33.8 ± 1.5% and 1.8 ± 0.2 gf/tex, respectively. The sulfur, copper and zinc content of the cashmere averaged 2.8 ± 0.1%, 0.00065 ± 0.00002% and 0.01276 ± 0.00025%, respectively. Rearing method significantly affected staple length, coefficient of variation of fiber diameter, cashmere tenacity and copper content. Males had a higher coefficient of variation of fiber diameter and cashmere tenacity than females (P < 0.05).
本研究旨在比较不同管理体系下饲养的公、母绒山羊的纤维品质特性和矿物质含量。从政府种羊站饲养的或在农村或游牧条件下商业饲养的 Raeini 绒山羊（<1.5 岁，n=48）中选择公、母羊。纤维的伸直长度、羊绒纤维直径、纤维直径变异系数、羊绒在羊毛中的百分比、羊毛在羊毛中的百分比和羊绒强度的平均值分别为 4.6±0.1cm、18.0±0.1μm、20.9±0.4%、66.1±1.5%、33.8±1.5%和 1.8±0.2gf/tex。羊绒中的硫、铜和锌含量分别为 2.8±0.1%、0.00065±0.00002%和 0.01276±0.00025%。饲养方式显著影响纤维的伸直长度、纤维直径变异系数、羊绒强度和铜含量。与雌性羊相比，雄性羊的纤维直径变异系数和羊绒强度更高（P<0.05）。
