Table 3 Glucose tolerance test factors and area under the curve (AUCground) for glucose and insulin during the glucose tolerance test conducted in 21 wk old castrated pigs in control and feed withdrawal (FW) treatments.

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