Based on the continuous progress of modern technology, large data processing was also setoff a boom in various industries. The authors engaged in animal nutrition and feed science research,large data analysis software combined with their own disciplines to "Bacillus subtilis" and contains "immune" as the search object, by searching on China Knowledge Network(CNKI), a total of 557 CNKI literature were confained. In this paper, the research of co-word analysis was taken as the gener-al idea, and the methods of social network analysis, keyword clustering analysis and multidimensionalscaling analysis were used to analyze the hotspots of Bacillus subtilis in recent years. The resultsshowed that the research directions and hotspots of Bacillus subtilis in China would focus on the fol-lowing three aspects: the growth performance, immunity and antioxidant function of Bacillus subtilis;the effect of Bacillus subtilis on the intestinal, the influence of Bacillus subtilis on the growth perfor-mance and serum biochemical index of livestock and poultry. The author speculated that the future re-search direction of Bacillus subtilis in this field might be as follows: the growth of Bacillus subtilis onlivestock and poultry, immune-related gene, the mechanism of Bacillus subtilis on the secretion of en-zymes in livestock and poultry, and the study on the length, weight and content of intestinal contentsof the intestine of livestock and poultry by Bacillus subtilis.
