This study was designed to evaluate the trace elements (minerals) in forages fed to sheep and their effect on gastrointestinal parasite burdens. The ultimate objective was to determine the correlation between the burden of gastrointestinal (GI) parasites and the level of trace minerals in sheep serum as a result of the forages they grazed on. A total of 384 faecal samples were collected from sheep in each of the districts (Sialkot and Multan) and examined quantitatively using the McMaster technique. Serum collected from them and plants were pre-treated, and spectrophotometry was used to determine the concentration of trace minerals (Mn, Co, Cu, and Zn). The level of these trace elements differed significantly (P < 0.05) in forages from both districts. In the district of Sialkot, the highest concentrations (mg/Kg) of Zn (38.53 ± 0.16) were found in , Cu (41.57 ± 0.07) in , Mn (39.61 ± 0.05) in , and Co (1.42 ± 0.03) in In the district of Multan, the highest concentrations (mg/Kg) of Zn (39.43 ± 0.46) were found in , Cu (25.76 ± 0.36) in , Mn (34.29 ± 0.53) in , and Co (1.74 ± 0.08) in . The prevalence of GI parasites in sheep populations in district Sialkot was 34%, while in district Multan, it was 32%. In tehsil Sialkot of district Sialkot, Zn and Cu were significantly (P < 0.05) correlated with eggs per gram (EPG) of faeces, while in tehsil Multan City of district Multan, only Cu was significantly (P < 0.05) correlated with EPG. The potential mechanism behind the role of trace minerals in lowering the burdens of GI parasites requires more investigation. It is recommended that plants with high content of trace minerals should be utilized as part of comprehensive preventive and control strategies against GI parasitism in ruminant animals like sheep.
本研究旨在评估喂给绵羊的草料中的微量元素（矿物质）及其对胃肠道寄生虫负荷的影响。最终目标是确定绵羊因所采食的草料而导致的胃肠道（GI）寄生虫负荷与血清中微量元素水平之间的相关性。从每个地区（锡亚尔科特和木尔坦）的绵羊中总共采集了384份粪便样本，并使用麦克马斯特技术进行定量检测。从绵羊和植物中采集的血清经过预处理，然后使用分光光度法测定微量元素（锰、钴、铜和锌）的浓度。这两个地区草料中这些微量元素的含量差异显著（P < 0.05）。在锡亚尔科特地区，在[具体植物名称未给出]中发现锌的最高浓度（mg/Kg）为（38.53 ± 0.16），在[具体植物名称未给出]中铜为（41.57 ± 0.07），在[具体植物名称未给出]中锰为（39.61 ± 0.05），在[具体植物名称未给出]中钴为（1.42 ± 0.03）。在木尔坦地区，在[具体植物名称未给出]中发现锌的最高浓度（mg/Kg）为（39.43 ± 0.46），在[具体植物名称未给出]中铜为（25.76 ± 0.36），在[具体植物名称未给出]中锰为（34.29 ± 0.53），在[具体植物名称未给出]中钴为（1.74 ± 0.08）。锡亚尔科特地区绵羊群体中胃肠道寄生虫的感染率为34%，而在木尔坦地区为32%。在锡亚尔科特地区的锡亚尔科特县（tehsil），锌和铜与每克粪便中的虫卵数（EPG）显著相关（P < 0.05），而在木尔坦地区的木尔坦市（tehsil），只有铜与EPG显著相关（P < 0.05）。微量元素在降低胃肠道寄生虫负荷方面所起作用的潜在机制需要更多的研究。建议将微量元素含量高的植物作为反刍动物（如绵羊）胃肠道寄生虫病综合防控策略的一部分加以利用。
