The purpose of this study was to supplement linseed oil and fish oil in the sows' diets to explore the effects of different types of oil sources for production, which expected to further investigate microbial mechanistic insight into the different type of oil sources. In this research, Landrace sows were selected and randomly divided into 3 groups: Control group (Ctrl), Linseed Group (LO), Fish Oil (FO). Results showed that there were no obvious changes in the sow's reproductive traits and the ingredients of colostrum. However, the content of Short-Chain Fatty Acids (SCFAs) were improved by LO and FO. Besides, in the absence of changes in the dominant bacteria, the relative abundances of microbial flora presented no significant differences at phylum level and genus level, and our study indicated that the discrepancy in the metabolic pathways of microorganisms in each treatment group further revealed the different adaptive mechanism of microorganisms between different oils sources. In summary, LO and FO had no effect on the sow's reproductive traits and the ingredients of colostrum, but increased the content of SCFAs, and differences in metabolic pathways suggest the adaptive mechanism of microorganisms due to the changes of diets.
