Apparent nutrient digestibility coefficient (%; ADC) in rainbow trout fed with four experimental diets1.

1Values represent least squares (LS) means (n = 3), row means with different superscript letters were significantly different and assigned only if interaction effect was significant (P2HP/EF - High P/E ratio diet with fat as main non-protein energy source; HP/EC - High P/E ratio diet with carbohydrate as main non-protein energy source; LP/EF - Low P/E ratio diet with fat as main non-protein energy source; LP/EC - Low P/E ratio diet with carbohydrate as main non-protein energy source.3ADC of total carbohydrates and energy includes the effect of the added cellulose (indigestible) in diets HP/EF and LP/EF.
