Effects of ad libitum feed intake in constant heat stress conditions (HS; 32°C) and pair-feeding in thermoneutral conditions (PFTN; 20°C) on plasma (A) glucose, (B) insulin, (C) C-peptide, (D) nonesterified fatty acids (NEFA); (E) rate of glucose infusion (ROGI); and (F) ROGI to euglycemic glucose concentration ratio in response to a hyperinsulinemic euglycemic clamp (HEC). Metabolites’ responses were calculated as the difference between the clamped and the baseline periods of the HEC. On period 1 (P1) all pigs were fed ad libitum in thermoneutral conditions. On period 2 (P2) pigs were exposed to either HS or PFTN. ^{a, b}Means with different letters differ (P ≤ 0.05)
