Heat stress remains a major environmental factor affecting poultry production. With growing concerns surrounding climate change and its antecedent of global warming, research on heat stress in poultry has gradually gained increased attention. Therefore, this study aimed to examine the current status, identify the research frontiers, and highlight the research trends on heat stress in poultry research using bibliometric analysis. The literature search was performed on the Web of Science Core Collection database for documents published from 2000 to 2021. The documents retrieved were analyzed for their publication counts, countries, institutions, keywords, sources, funding, and citation records using the bibliometric app on R software. Network analysis for co-authorship, co-occurrence, citation, co-citation, and bibliographic coupling was visualized using the VOSviewer software. A total of 468 publications were retrieved, and over the past two decades, there was a gradual increase in the annual number of publications (average growth rate: 4.56%). China had the highest contribution with respect to the number of publications, top contributing authors, collaborations, funding agencies, and institutions. Nanjing Agricultural University, China was the most prolific institution. Kazim Sahin from Firat University, Turkey contributed the highest number of publications and citations to heat stress in poultry research, and Poultry Science was the most productive and the most cited journal. The top 10 globally cited documents mainly focused on the effects of heat stress, alleviation of heat stress, and the association between heat stress and oxidative stress in poultry. All keywords were grouped into six clusters which included studies on "growth performance", "intestinal morphology", "heat stress", "immune response", "meat quality", and "oxidative stress" as current research hotspots. In addition, topics such as; "antioxidants", "microflora", "intestinal barrier", "rna-seq", "animal welfare", "gene expression", "probiotics", "feed restriction", and "inflammatory pathways" were identified for future research attention. This bibliometric study provides a detailed and comprehensive analysis of the global research trends on heat stress in poultry over the last two decades, and it is expected to serve as a useful reference for potential research that will help address the impacts of heat stress on poultry production globally.
热应激仍然是影响家禽生产的主要环境因素。随着人们对气候变化及其全球变暖先兆的日益关注，家禽热应激方面的研究逐渐受到更多关注。因此，本研究旨在通过文献计量分析来审视家禽热应激研究的现状，确定研究前沿，并突出研究趋势。在科学网核心合集数据库中对2000年至2021年发表的文献进行检索。使用R软件中的文献计量应用程序对检索到的文献进行发表数量、国家、机构、关键词、来源、资金和引用记录等方面的分析。使用VOSviewer软件将合著、共现、引用、共引和文献耦合的网络分析可视化。总共检索到468篇出版物，在过去二十年中，年出版物数量呈逐渐增加趋势（平均增长率：4.56%）。在出版物数量、顶级贡献作者、合作、资助机构和机构方面，中国的贡献最大。中国南京农业大学是发文量最多的机构。土耳其菲拉特大学的卡齐姆·萨欣在禽热应激研究方面的出版物和引用数量最多，《家禽科学》是发表量最大且被引用最多的期刊。全球被引用次数最多的前10篇文献主要集中在家禽热应激的影响、热应激的缓解以及热应激与氧化应激之间的关联。所有关键词被分为六个聚类，包括“生长性能”“肠道形态”“热应激”“免疫反应”“肉质”和“氧化应激”等方面的研究，这些是当前的研究热点。此外，还确定了如“抗氧化剂”“微生物群”“肠道屏障”“RNA测序”“动物福利”“基因表达”“益生菌”“限饲”和“炎症途径”等主题以供未来研究关注。这项文献计量研究对过去二十年全球家禽热应激研究趋势进行了详细而全面的分析，预计将为有助于应对热应激对全球家禽生产影响的潜在研究提供有用参考。
