Timeline of the experimental protocol. Rats were maintained with parenteral nutrition (PN) for 7 days with continuous intravenous infusion of a low-dose of glucagon-like peptide-2 (GLP-2). Treatment groups were given partial enteral nutrients (EN) from a semielemental, low-residue liquid diet with different sources of protein for days 4–7 with a reduction in the volume of PN.
