摘要: 为了研究遗传及环境对羊毛生产性状的影响,利用高效液相色谱法测定了新疆地区和田羊、卡拉库尔羊、多浪羊、中国美利奴羊4个绵羊品种羊毛中的17种氨基酸含量,探索不同品种绵羊间和同一品种不同品系绵羊间羊毛氨基酸含量的差异。结果表明,和田羊羊毛的氨基酸总含量显著高于多浪羊羊毛,差异显著(P<0.05);其他品种间氨基酸总量差异不显著。多浪羊羊毛中的Asp、Ser、Glu、Arg、Thr、Ala、Pro、Val、Lys、Ile、Leu、Phe等氨基酸含量均低于其他品种;卡拉库尔羊羊毛只有Cys含量高于其他品种,Ser、Gly、Thr、Pro、Tyr等氨基酸含量均低于其他品种。各品种羊毛的螺旋比值(促螺旋氨基酸含量/阻螺旋氨基酸含量),中国美利奴为0.90,卡拉库尔羊为0.79,和田羊为0.77,多浪羊为0.75。结果表明,和田羊氨基酸总含量高于其他品种,中国美利奴螺旋比值高于其他品种,卡拉库尔羊Cys含量高于其他品种。

Abstract: For searching the differences of amino acids content between the different breeds of sheep or the different strains of the same breed,the content of 17 amino acids of wool in 4 breeds,including Hetian sheep (Pure plain Hetian,Pure mountain Hetian and New Hetian strains),Karakul sheep (Silkworm,girdle-type and rib-type three flower-types),Duolang sheep and Chinese Merino was determined by high performance liquid chromatography (HPLC). The results showed that the total amino acid content of wool from Hetian sheep was higher than that of Duolang sheep,and the difference was statistically significant(P<0.05). The differences in amino acids content were not statistically significant between the other breeds(P>0.05). Those amino acids in Duolang sheep such as Asp,Ser,Glu,Arg,Thr,Ala,Pro,Val,Lys,Ile,Leu,Phe were lower than that of the other breeds. The content of Cys in Karakul sheep was higher than that of the other breeds,but Ser,Gly,Thr,Pro,Tyr were lower than that of the other breeds. The ratio of α-helix promoting/α-helix inhibiting amino acids in the wool,Chinese Merino was 0.90,while Karakul sheep was 0.79,Hetian sheep was 0.77 and Duolang sheep was 0.75.The results showed that, total amino acids of Hetian sheep wool was higher than that of other species, the helix ratio of Chinese Merino wool was higher than that of other species,the cystines of Karakul and Hetian sheep wool were higher than that of other species.

Key words: Hetian sheep; Karakul sheep; Duolang sheep; Chinese Merino; wool; amino acids content
