  1. RGR = Relative growth rate, RCR = Relative consumption rate, ECI = Efficiency of conversion of ingested food, ECD = Efficiency of conversion of digested food, AD = Approximate digestibility. Values are Mean ± SE. Means followed by different superscript letters within a column are significantly different (p ≤ 0.05) based on Tukey’s test. **Significant at 1%, NS non-significant.
