^†IBW: initial body weight.

^§ABW: average body weight (initial body weight + final body weight)/2.

^aMean values and standard deviation (±SD) are presented for each parameter (n = 3).

Significant differences within the diets are indicated by different letters (Tukey test, P < 0.05).

^bDGI: ((final body weight^1/3 - initial body weight^1/3)/time in days) × 100.

^cFE: (wet weight gain/dry feed intake).

^dPER: (wet weight gain/crude protein intake).
