Fourteen body measurements of 132 adult female camels belonging to three populations Guerzni (60), Khouari (28), and Marmouri (44) reared in 38 herds of 8 provinces of Southern Morocco were studied to identify homogeneous groups according to their conformation. The measurements were chest girth (CG), hump girth (HG), height at withers (HW), body length (BL), fore limb length (FLL), chest width (CW), chest depth (CD), fore hoof circumference (FHC), head length (HL), distance between eyes (DE), ear length (EL), neck length (NL), neck circumference (NC), and tail length (TL). The three populations were compared according to their mean body measurements and through multivariate analyses. The results revealed that only HG, HW, BL, and FLL were significantly influenced by the population. Moreover, the MANOVA showed that Guerzni and Marmouri populations were significantly different, whereas Khouari was not significantly different either from Guerzni or Marmouri populations. Discriminant analysis showed that out of 14 variables, BL and FLL were the most discriminant and resulted into two significant canonical variables (CAN1 and CNA2). Khouari population could be best discriminated from Guerzni and Marmouri by CAN1, and Guerzni could be best distinguished from Marmouri by CAN2. The discriminant analysis revealed that 46.7%, 60.7%, and 40.9% of Guerzni, Khouari, and Marmouri animals, respectively, were correctly classified in their original population. The clustering of the three populations highlighted two Moroccan camel groups: Guerzni and Marmouri in the first group and Khouari in the second one.
对摩洛哥南部8个省份38个牧群中饲养的132头成年雌性骆驼进行了14项身体测量,这些骆驼分属于盖尔兹尼(60头)、胡阿里(28头)和马尔穆里(44头)三个种群,旨在根据其体型确定同质群体。测量项目包括胸围(CG)、驼峰围(HG)、肩高(HW)、体长(BL)、前肢长度(FLL)、胸宽(CW)、胸深(CD)、前蹄周长(FHC)、头长(HL)、两眼间距(DE)、耳长(EL)、颈长(NL)、颈围(NC)和尾长(TL)。根据平均身体测量数据并通过多变量分析对这三个种群进行了比较。结果显示,只有HG、HW、BL和FLL受种群影响显著。此外,多变量方差分析表明,盖尔兹尼种群和马尔穆里种群有显著差异,而胡阿里种群与盖尔兹尼种群或马尔穆里种群相比均无显著差异。判别分析表明,在14个变量中,BL和FLL的判别能力最强,并产生了两个显著的典型变量(CAN1和CNA2)。通过CAN1可以最好地将胡阿里种群与盖尔兹尼种群和马尔穆里种群区分开来,通过CAN2可以最好地将盖尔兹尼种群与马尔穆里种群区分开来。判别分析显示,盖尔兹尼、胡阿里和马尔穆里种群的动物分别有46.7%、60.7%和40.9%被正确归类到其原始种群中。这三个种群的聚类突出了两个摩洛哥骆驼群体:第一组是盖尔兹尼和马尔穆里,第二组是胡阿里。
