Initial and final weights and lengths (n = 15), HSI (n = 75) and VSI (n = 75). Effects of diet factor and genetic factor on the biometric parameters are determined by two-way ANOVA. Results are expressed as mean +/- S.D. and significant differences are indicated by the p value (two-way ANOVA, P < 0.05).
