Due to climate change, heat stress is a growing problem for the dairy industry. Based on this, annual economic losses in the dairy sector are verified mainly on a large scale. Despite several publications on thermal stress in lactating dairy cows in confinement systems, there need to be published reviews addressing this issue systematically. Our objective was to scientometrically analyze the effects of heat stress in dairy cows managed in a confinement system. Based on PRISMA guidelines, research articles were identified, screened, and summarized based on inclusion criteria for heat stress in a confinement system. Data was obtained from the Web of Science. A total of 604 scientific articles published between 2000 and April 2022 were considered. Data was then analyzed using Microsoft Excel and CiteSpace. The results pointed to a significant increase in studies on heat stress in lactating cows housed in confinement systems. The main research areas were Agriculture, Dairy Animal Science and Veterinary Sciences. The USA showed the highest concentration of studies (31.12%), followed by China (14.90%). Emerging themes included heat stress and behavior. The most influential journals were the Journal of Dairy Science and the Journal of Animal Science. The top authors were L. H. Baumgard and R. J. Collier. The leading institutions were the Chinese Academy of Agricultural Sciences, followed by the State University System of Florida and the University of Florida. The study maps the significant research domains on heat stress of lactating cows in confinement systems, discusses implications and explanations and highlights emerging trends.
由于气候变化，热应激对乳制品行业来说是一个日益严重的问题。基于此，乳制品行业的年度经济损失主要在大规模范围内得到证实。尽管有几篇关于圈养泌乳奶牛热应激的出版物，但仍需要有系统地论述这一问题的综述发表。我们的目标是对圈养系统中管理的奶牛热应激影响进行科学计量分析。根据PRISMA指南，基于圈养系统热应激的纳入标准对研究文章进行识别、筛选和总结。数据来自科学网。共考虑了2000年至2022年4月期间发表的604篇科学文章。然后使用微软Excel和CiteSpace对数据进行分析。结果表明，圈养泌乳奶牛热应激研究显著增加。主要研究领域为农业、奶牛科学和兽医学。美国的研究集中度最高（31.12%），其次是中国（14.90%）。新兴主题包括热应激与行为。最具影响力的期刊是《乳品科学杂志》和《动物科学杂志》。顶尖作者是L. H. 鲍姆加德和R. J. 科利尔。领先机构是中国农业科学院，其次是佛罗里达州立大学系统和佛罗里达大学。该研究绘制了圈养系统中泌乳奶牛热应激的重要研究领域图，讨论了其影响和解释，并突出了新兴趋势。
