One hundred camels (Camelus dromedaries) and fifty sheep and goats being adult, male, and apparently healthy field animals were studied to provide data regarding the normal values of some hepatic trace elements. Liver samples were collected during postmortem examination, digested, and analyzed for Cu, Zn, Fe, Co, and Mn using atomic absorption spectrophotometry. The results showed that the differences in mean liver concentrations of Cu, Zn, Fe, and Co between camels, sheep, and goats were statistically significant (P < 0.05). Hepatic Cu, Fe, and Co concentrations were higher in camels than in sheep and goats. All liver samples were adequate for Fe and Co, whereas only camel liver was adequate for Cu. In camels, hepatic Zn concentration was inadequately lower than that in sheep and goats. No difference in Mn concentration was detected between camels, sheep, and goats. All liver samples were inadequate compared to free-ranging herbivores. In camels, significant correlation (r (2) = -0.207, P value = 0.04) was detected between Zn and Co, whereas in sheep significant correlation (r (2) = -0.444, P value = 0.026) was detected between Zn and Mn. No significant correlation between trace elements was detected in goats.
对100头成年单峰骆驼（骆驼属单峰驼）以及50只成年、雄性且外表健康的野外绵羊和山羊进行了研究，以获取有关某些肝脏微量元素正常数值的数据。在尸检过程中采集肝脏样本，进行消化处理，并使用原子吸收分光光度法分析铜（Cu）、锌（Zn）、铁（Fe）、钴（Co）和锰（Mn）的含量。结果表明，骆驼、绵羊和山羊肝脏中铜、锌、铁和钴的平均含量差异具有统计学意义（P < 0.05）。骆驼肝脏中的铜、铁和钴含量高于绵羊和山羊。所有肝脏样本中的铁和钴含量充足，而只有骆驼肝脏中的铜含量充足。在骆驼中，肝脏锌含量低于绵羊和山羊，含量不足。骆驼、绵羊和山羊之间的锰含量未检测到差异。与野生食草动物相比，所有肝脏样本中的含量均不足。在骆驼中，锌和钴之间存在显著相关性（r (2) = -0.207，P值 = 0.04），而在绵羊中，锌和锰之间存在显著相关性（r (2) = -0.444，P值 = 0.026）。在山羊中未检测到微量元素之间的显著相关性。
