摘　　要：测定了怀头他拉乡本地山羊和辽宁绒山羊♂×本地羊♂的Ｆ＿１、Ｆ＿２及互交一代羊的绒纤维物理性状。测定结果：实际绒毛比例，本地羊平均为４５：５５，Ｆ＿１、Ｆ＿２及互交一代羊平均为６３：３７；山羊绒自然长度在３．９２─６．４８ｃｍ间，伸直长度平均７．０２ｃｍ（６．０１─８．５９ｃｍ），绒纤维细度平均１３．９９μｍ（１２．９５─１５．２７μｍ），强力平均４．７２ＣＮ（３．８５─６．０５ＣＮ），伸度平均３８．０５％（２５．４２％─４４．８９％）；净绒率平均６２．１２％（４８．３％─７６．１４％），其中，本地羊平均６０．５８％（４８．３％─６９．５４％），Ｆ＿１、Ｆ＿２及互交一代羊平均６２．５１％（５３．６３％─７６．１４％）。结果表明，怀头他拉山羊绒品质优良。Cashmere physical characteristics of the Huaitoutala Goat C the Local goat、F_1,F_2 and reciprocal cross F_1 of the Liaoning Cashmere Goat ♂× the Local Goat ♂)weretested. The results showed:Actual ratio of cashmere/hair was 45:55 for the Local Goat.63:37 for F_1、 F_2 and reciprocal cross F_1; In all examined goats; natural length of cashmere was3. 92-6; 48 cm,average stretched:ength was 7. 02cm(6. 01-8. 59cm),average fineness ofcashmere was 13. 99um(12. 95-15.27um),average strength was 4. 72CN(3. 85-6.05CN),average etasticity,vas 38.05%(25.42%-44. 89%),average net cashere ratio In all examinedgoats was 62.12%(48.3%-76. 14%),inctuding 60. 58%(48.3%-69.54%)for the LocalGoat.62.15%(53. 63%-76. 14%)for F_1,F_2 and reciprocal cross F_1 It was demonstratedthat the quality of Huaitoutala Cashmere was excellent
