Fig. 2

Metabolites concentrations in extracellular fluids of subcutaneous adipose tissues after ingestion at lactation d 28. Zero min represents the extracellular fluid collected within 15 min before ingestion, representing a fasting state. This figure shows effects of diet, time, and diet × time interactions on dynamic changes of glutamate (a, P_diet = 0.001, P_time = 0.51, P_{diet × time} = 0.43), glucose (b, P_diet = 0.18, P_time = 0.001, P_{diet × time} = 0.76), lactate (c, P_diet = 0.59, P_time < 0.0001, P_{diet × time} = 0.97), Pyruvate/Glucose (d, P_diet = 0.029, P_time < 0.0001, P_{diet × time} = 0.001), Lactate/Glucose (e, P_diet = 0.20, P_time < 0.0001, P_{diet × time} = 0.002), pyruvate (f, P_diet = 0.75, P_time = 0.22, P_{diet × time} = 0.72), Lactate/Pyruvate (g, P_diet = 0.23, P_time = 0.45, P_{diet × time} = 0.49). Values are least-squares means with SE. The differences between time points within a group were indicated by superscripts with no common letters, while differences between groups at a specific time point were indicated by asterisk. It was considered significant at P < 0.05. CON, control; RFA, restricted feed allowance; Pyruvate/Glucose, the ratio of pyruvate to glucose; Lactate/Glucose, the ratio of lactate to glucose; Lactate/Pyruvate, the ratio of lactate to pyruvate
