Effect of tributyrin (TB) on the concentrations of insulin and leptin in the serum of piglets with intrauterine growth retardation (day 21).

Data are expressed as mean ± SEM, n = 6; SEM, standard error of mean. a,b,c Mean values within a line with different superscript letters were significantly different (P < 0.05). NBW, piglets with a normal birth weight that were fed with basic milk diets; IUGR: piglets with intrauterine growth retardation that were fed with basic milk diets; IT, piglets with intrauterine growth retardation that were fed with diets supplemented with 0.1% TB. HOMA-IR = [fasting glucose (mmol/L)×fasting insulin (μU/ml)] / 22.5; HOMA-IR, homeostasis model of assessment for insulin resistence index.
