本研究的目的是测量羊驼各种颜色的毛发黑色素，并找出羊驼黑色素数量与毛发颜色表型之间的关系。根据孟塞尔颜色系统，22种不同毛色表型各选择3只健康羊驼（共66只羊驼）。从侧胸区域取羊驼毛，然后用不同的溶液溶解以获得黑色素。采用分光光度法测定碱溶性黑色素（ASM）、真黑素（EM）和褐黑素（PM）的值，并分别标记为Sp.ASM、Sp.EM和Sp.PM。采用SPSS11.5软件对数据进行分析。结果表明，随着颜色从白色到黑色加深，平均Sp.ASM和Sp.PM增加，Sp.ASM的范围为0.500至4.543，Sp.EM的范围为0.268至1.457。然而，平均 Sp.PM 与颜色没有如此明显的关系。根据Sp.ASM和EM的值，产生7种色调，灰色是单一色调。大多数数据呈正态分布（p>0.10）。 ANOVA分析显示Sp.ASM、Sp.EM和Sp.PM的平均值存在显着差异(p<0.05)。结果还表明，Sp.ASM与Sp.EM呈正相关，但Sp.ASM与Sp.PM之间的相关性与0无显着性差异。由此得出结论：EM是羊驼毛黑色素的主要成分； ASM、EM 和羊驼毛颜色之间存在显着相关性，而 EM 是区分这些群体的最可靠参数。
The aim of this study was to measure the hair melanins of various colors and to find the relationship between the quantity of melanins and hair color phenotypes in alpacas. According to the Munsell color system, 3 healthy alpacas were selected for each of the 22 different hair color phenotypes (66 alpacas altogether). Alpaca hair was taken from the lateral thoracic region and then dissolved with different solutions to obtain melanins. The values of alkali-soluble melanins (ASM), eumelanin (EM) and pheomelanin (PM) were measured by spectrophotometric assay, and labeled as Sp.ASM, Sp.EM and Sp.PM, respectively. Data were analyzed using SPSS11.5 software. Results showed that average Sp.ASM and Sp.PM were increased as the color deepened from white to black, ranging from 0.500 to 4.543 for Sp.ASM and from 0.268 to 1.457 for Sp.EM. However, average Sp.PM had no such apparent relationship with color. Based on the value of Sp.ASM and EM, 7 hues were produced and gray was a single hue. Most of the data were in a normal distribution (p>0.10). ANOVA analysis showed that mean values of Sp.ASM, Sp.EM and Sp.PM were significantly different (p<0.05). The results also showed that Sp.ASM was positively correlated with Sp.EM but the correlation between Sp.ASM and Sp.PM was not significantly different from 0. It is concluded that EM is the major constituent of alpaca hair melanin; there is a significant correlation among ASM, EM and alpaca hair colors, and EM is the most reliable parameter for distinguishing these groups.
