Effects of cold stress on the cecal SCFAs and cytokines of Hu sheep and Hulunbuir sheep. A Composition of SCFAs. B Differential analysis of major cecal SCFA indices; A/P: acetate/propionate ratio. C Differential analysis of cecal inflammatory cytokines. Differences between two groups were identified using independent two-way ANOVA. Significance is indicated by symbols (**, P < 0.01; *, P < 0.05; #, 0.05 ≤ P < 0.1)
