Food efficiency: the ratio of daily energy intake/daily weight gain. Results are expressed as means ± SDs. Pancreatectomized (Px) rats fed (1) 0.5 g dextrin/kg bw (Px-CON), (2) 0.05 g acid hydrolyzed silk peptides(SPs)/kg bw (SP-L), (3) 0.1 g SPs/kg bw (SP-M), (4) 0.5 g SPs/kg bw (SP-H), and (5) 0.04 g metformin/kg bw (positive-CON) with a high fat diet. Sham-operated rats (normal-CON) fed the same diet of Px-CON. a,b,c,d Values on the same row with different superscripts were significantly different at p < 0.05.
