在热带地区，骆驼的产肉率仍在调查中，以确定更好的肉品种或类型。因此，四个单峰的沙特阿拉伯（SA）骆驼品种，Majaheem，Maghateer，Hamrah和Safrah进行了实验，以区分它们彼此的基础上肉测量。这些测量是在每个品种的六个完整的雄性上测量的生物统计学肉类性状。结果表明，除了屠宰率和肋眼面积等少数情况外，马扎希姆品种的各项指标均高于其他品种。在分化分析中，最具鉴别力的肉类变量是肌原纤维蛋白指数，肉色成分（L* 和a*，B*），和烹饪损失。因此，Safrah和Majaheem品种提出了最大的差异，证明了他们的多元手段。典型判别分析允许品种之间的分化的额外的理解。此外，还有两个大的集群，一个是由Hamrah和Maghateer组成的，沿着有Safrah。这些分类可能会将每个品种分配到一个集群中，因为它们是更好的肉类生产者。Majaheem单独聚集在另一个集群中，这可能是由于更好的牛奶生产商。然而，SA骆驼品种的生产力类型需要进一步的形态学和遗传学描述。
The meat productivity of camel in the tropics is still under investigation for identification of better meat breed or type. Therefore, four one-humped Saudi Arabian (SA) camel breeds, Majaheem, Maghateer, Hamrah, and Safrah were experimented in order to differentiate them from each other based on meat measurements. The measurements were biometrical meat traits measured on six intact males from each breed. The results showed higher values of the Majaheem breed than that obtained for the other breeds except few cases such dressing percentage and rib-eye area. In differentiation analysis, the most discriminating meat variables were myofibrillar protein index, meat color components (L* and a*, b*), and cooking loss. Consequently, the Safrah and the Majaheem breeds presented the largest dissimilarity as evidenced by their multivariate means. The canonical discriminant analysis allowed an additional understanding of the differentiation between breeds. Furthermore, two large clusters, one formed by Hamrah and Maghateer in one group along with Safrah. These classifications may assign each breed into one cluster considering they are better as meat producers. The Majaheem was clustered alone in another cluster that might be a result of being better as milk producers. Nevertheless, the productivity type of the camel breeds of SA needs further morphology and genetic descriptions.
