Our objective was to determine how intravenous or intragastric feeding affects serum concentrations of insulin-like growth factor (IGF)-I and- II and IGF binding proteins (IGFBP), and hepatic abundance of IGF-I mRNA. Male Fischer 344 rats (235-246 g) were fed for 14 d by intravenous or intragastric infusion with total parenteral nutrihon (TPN) solutions providing 65% of energy from long-chain triglyceride (LCT) or a 3: 1 admixture of medium-chain triglyceride (MCT) and LCT emulsions (MCT/LCT). Twice as much TPN solution was required per gram of weight gain with MCT/LCT compared with LCT infusion (P<0.0003). Serum IGF-I and -II concentrations and hepatic IGF-I mRNA abundance were not significantly different.
