The objectives were to describe the morphometric measurements and determine the best model for estimating the relationship between body weight and morphometric measurements of the two Sudanese antelopes, Dorcas Gazelle (Gazella dorcas) and Bohor Reedbuck (Redunca redunca). Twenty-four animals belonging to two Sudanese antelope species, six males and six females from each species were used. Data on body weight and body measurements were recorded from each species. Averages of body weight and morphometric traits of Bohor Reedbuck were larger than the corresponding values of Dorcas Gazelle, while the opposite was true in the case of horn thickness, which was larger in the later. Stepwise regression analysis indicated that, the best model for Dorcas Gazelle had the variables neck length, belly girth and chest height, while Bohor Reedbuck had body length, head length, neck length, tail length, chest girth and pelvic height. These variables explained 82% of the total variation in body weight of Dorcas Gazelle, and 92% of the variation of Bohor Reedbuck. These results are discussed in relation to morphometric measurements reported for antelopes elsewhere.
目的是描述形态测量学测量值，并确定最佳模型来估计两种苏丹羚羊（Gazella dorcas 和 Redunca redunca）的体重与形态测量学测量值之间的关系。使用了属于两种苏丹羚羊物种的 24 只动物，每种动物有 6 只雄性和 6 只雌性。从每个物种记录体重和身体测量数据。Bohor Reedbuck 的体重和形态特征平均值大于 Dorcas Gazelle 的相应值，而角厚度则相反，后者更大。逐步回归分析表明，对于 Dorcas Gazelle，最好的模型有颈长、腹围和胸高这三个变量，而 Bohor Reedbuck 则有体长、头长、颈长、尾长、胸围和骨盆高这五个变量。这些变量解释了 Dorcas Gazelle 体重总变异的 82%，Bohor Reedbuck 体重变异的 92%。这些结果与其他地方报道的羚羊形态测量学测量值进行了讨论。
