Table 4 Correlation coefficients for parameters associated with area under the curve (AUC) for glucose and insulin during the glucose tolerance test conducted in 21 wk old castrated pigs from control and feed withdrawal (FW) treatments.

From: Periodic 48 h feed withdrawal improves glucose tolerance in growing pigs by enhancing adipogenesis and lipogenesis
