Values are mean of triplicates (n=3) and presented as mean ± SD.
The determined dietary PA levels were 16, 107, 226, 317 and 424 mg kg–1 for P0, P100, P200, P300 and P400, respectively.
SGR = {[loge final body weight (mg) - loge initial body weight (mg)] / days} × 100.
FCR = feed intake (mg) / wet weight gain (mg).
PER = wet weight gain (mg) / total protein given (mg).
Significance probability associated with the F-statistic.
Different superscripts in each column indicate significant differences (p < 0.05).
FBW, final body weight; SGR, specific growth rate; FCR, feed conversion ratio; PER, protein efficiency ratio; ANOVA, analysis of variance.
