Based on keyword co-occurrence analysis and literature co-citation analysis, a total of 1 026 international scientific papers about genetic mechanisms of heat stress in dairy cattle from Science Citation Index database from 1990 to 2020 were analyzed, including the authors, institutions and the annual number of publications. The co-occurrence network of co-cited literatures and important keywords in this field also were drawn. By the literatures with high citation frequency and the keywords with high frequency, the overall research situation and hotspots were showed, and the development context and trend were interpreted in this field. Furthermore, based on 52 Chinese scientific papers in this field from CNKI database, the research progress on genetic mechanism of heat stress in dairy cattle in China was summarized. By the co-occurrence of keywords and co-citation analysis of literatures at home and abroad, it was found that heat shock proteins, single nucleotide polymorphisms, oxidative stress and reproductive performance were research hotspots in this field. With the deepening of research in this field, it has gradually developed from the expression analysis of genes to identifying single nucleotide polymorphisms related to heat-resistance and exploring the regulation mechanisms of genes related to heat stress in dairy cattle. In the expression regulation of genes related to heat stress, epigenetics and miRNA played important roles. In the genetic mechanisms research for heat stress in dairy cattle, this paper could be beneficial for understanding research situation and knowledge structure in this field, and help quickly finding the primary focus and key literature.
