Comparison of the functional capacities of the gut microbiomes between Nursing and Weaned piglets associated with nutrition. Normalized abundance of the level 3 SEED subsystem classified reads associated with carbohydrate metabolism (a) and amino acid metabolism (b). The error bars show the calculated standard deviation of four replicates, and the [P < 0.001], [P < 0.01] and [P < 0.05] were indicated as [***], [**] and [*], respectively
