Fig. 5From: Early inoculation with caecal fermentation broth alters small intestine morphology, gene expression of tight junction proteins in the ileum, and the caecal metabolomic profiling of broilersVolcano plots of caecal metabolites of 7-day-old (a) and 14-day-old (b) broilers. The red dot represents a significantly different metabolite that is more concentrated in the F group, while the blue dot represents a metabolite that was mainly enriched in the C group. The dot size indicates the variable importance in the projection (VIP) value. Fold Change: mean value of peak area obtained from the F group/mean value of peak area obtained from the C groupBack to article page
