The objective was to investigate the context, approach and research topics present in the papers that analysed trace elements in beef cattle to identify gaps and scientific perspectives for the sustainable management of trace elements in livestock. The main research groups came from the United States, Spain, Japan, Brazil, India and Slovakia, which represented 31% of the papers produced. Only 37% of studies addressed aspects that integrated animal, environmental and human health. The reviewed papers concerned 56 elements and 15 bovine tissues (Cu, Zn, Pb, liver, muscle and kidney highlighted). The main gaps were (1) lack of research in developing countries, (2) the need to understand the impact of different environmental issues and their relationship to the conditions in which animals are raised, and (3) the need to understand the role of many trace elements in animal nutrition and their relationship to environmental and human health. Finally, we highlight possible ways to expand knowledge and provide innovations for broad emerging issues, primarily through expanding collaborative research networks. In this context, we suggest the adoption of the One Health approach for planning further research on trace elements in livestock. Moreover, the One Health approach should also be considered for managers and politicians for a sustainable environmental care and food safety.
目的是调查分析肉牛微量元素的论文中所呈现的背景、方法和研究主题，以确定家畜微量元素可持续管理方面的差距和科学观点。主要研究团队来自美国、西班牙、日本、巴西、印度和斯洛伐克，这些国家的研究团队发表的论文占总数的31%。只有37%的研究涉及整合动物、环境和人类健康的方面。综述的论文涉及56种元素和15种牛组织（重点提及铜、锌、铅、肝脏、肌肉和肾脏）。主要差距在于：（1）发展中国家缺乏研究；（2）需要了解不同环境问题的影响及其与动物饲养条件的关系；（3）需要了解许多微量元素在动物营养中的作用及其与环境和人类健康的关系。最后，我们强调了扩大知识和为广泛出现的新问题提供创新的可能途径，主要是通过扩大合作研究网络。在此背景下，我们建议采用“同一健康”方法来规划关于家畜微量元素的进一步研究。此外，管理者和政治家在进行可持续环境护理和食品安全工作时也应考虑“同一健康”方法。
