Fig. 4.

The metabolome view map of the significant metabolic pathways characterized in the liver of the growing heifers of the LD and LA group. This figure shows the pathways that are significantly changed based on enrichment and related indicators. The X-axis represents the pathway impact, and the Y-axis represents pathway enrichment. Larger sizes and darker colors indicate greater pathway enrichment and higher pathway impact values, respectively. LD group, growing heifers fed a Lys-deficient diet; LA group, growing heifers fed a Lys-adequate diet.
