Volcano plot of metabolites with significant differences between the control and itaconic acid groups in broilers at 42 days of age (n = 6). The size of the circles (VIP values) indicates the extent of the contribution of the marker metabolite to the difference between the control and itaconic acid groups. Broilers in the control group were fed a basal diet, and broilers in the itaconic acid group were fed a basal diet supplemented with 6 g/kg itaconic acid
