Alpha and Beta diversity of the microbial community according to the experimental group. a Alpha diversity, means are presented by black horizontal lines and SD as grey error bars; b-c nMDS representation of the beta diversity (Bray Curtis, stress = 0.17) according to (b) axes 1 and 2 and (c) axes 1 and 3. Conv: Conventional breeding system, Alt: Alternative breeding system. Cconv: Control group before overfeeding, OF: Overfed group, Calt: Control group before Ad libitum corn mixture feeding, NegSF: Negative response groupe to spontaneous fattening induction, PosSF: Positive response groupe to spontaneous fattening induction. Within a plot, groups with different superscripts differ (P < 0.05) according to a Wilcoxon non parametric test
