The glucose disposition of intravenous glucose tolerance test (IVGTT) in low-fat and HFHF diet fed pigs. All pigs were subjected to IVGTT at the 9- (a) and 12- (b) month time points. Briefly, the fasting pigs were injected with glucose solution, 0.5 g/kg body weight, via a jugular vein. For analyzing IVGTT results, the area under the curve (AUC) of glucose level (c) and 2-h postload glucose level (d) are shown. Data are expressed as means ± SEM (low-fat diet, n = 3; HFHF diet, n = 4). *p < 0.05, **p < 0.01. NS not significant
