Organ weights are expressed relative to final body weight. Results are expressed as mean ± SEM; n = 8–20 per group. BW, body weight; CEN, continuous enteral nutrition; FORM, intermittent formula feeding; IEN, intermittent enteral nutrition; PN, parenteral nutrition; SI, small intestine.

different from PN, CEN, IEN, and FORM, respectively; P < .05.
