Effects of dietary NaB on growth performance of juvenile turbot.
| Diet | Control | High SBM | High SBM + 0.2%NaB | High SBM + 0.5%NaB |
|---|---|---|---|---|
| Survival (%) | 97.50 ± 1.44 | 93.33 ± 0.83 | 95.83 ± 0.83 | 92.50 ± 3.82 |
| Final weight (g) | 76.34 ± 1.54b | 65.83 ± 1.44a | 76.00 ± 2.08b | 73.83 ± 2.20b |
| Weight gain rate (%) | 247.00 ± 7.00b | 199.20 ± 6.57a | 245.45 ± 9.46b | 235.61 ± 10.02b |
| Specific growth rate (%/d) | 2.22 ± 0.04b | 1.96 ± 0.04a | 2.21 ± 0.05b | 2.16 ± 0.05b |
| Feed efficiency ratio | 1.14 ± 0.03 | 1.05 ± 0.02 | 1.07 ± 0.02 | 1.08 ± 0.03 |
| Feed intake (%) | 1.73 ± 0.03 | 1.69 ± 0.03 | 1.84 ± 0.05 | 1.79 ± 0.06 |
| Hepatosomatic index (%) | 1.34 ± 0.07 | 1.33 ± 0.06 | 1.46 ± 0.05 | 1.41 ± 0.04 |
Survival (%) = 100 × (the final number of fish/the initial number of fish); Weight gain rate (WGR, %) = 100 × (final body weight-initial body weight) /initial body weight; Specific growth rate (SGR, %/d) = 100 × (Ln final body weight—Ln initial body weight)/days; Feed efficiency ratio, FER = weight gain (g)/total amount of feed consumption (g); Feed intake, FI (%BW/day) = 100 × feed consumption/(final body weight + initial body weight)/2)/day; Hepatosomatic index (HSI, %) = 100 × liver weight (g) of final individual fish/final individual weight (g).
*Values were presented as means ± SEM (n = 3 replicates). Multiple comparisons were conducted with Tukey’s test. And values in the same row with different letters were significantly different (P < 0.05).
