1Experimental diet: S = starch, P = protein, L = lipid, E = energy. Capital, lowercase letters and letters with underline meant high, low and medium dietary concentration, respectively. For example, diet Spl contained high starch concentration and low protein and lipid concentrations. Diet PE contained high protein and high energy, respectively.
