*Values are means of triplicate groups ± S.E.M. Within a row, means with different letters are significantly different (P < 0.05); means with the same letters are not significantly different (P > 0.05). Absence of letters indicates no significant difference between treatments. Crude protein, crude lipid, and ash are expressed on a wet weight basis.
1Initial values are not included in the statistical analysis.
