Feed Nitrogen retention as % of feed Total nitrogen loss (mg) Nitrogen loss / g of shrimp produced (mg/g) Nitrogen loss / g of feed consumed (mg/g)
1 76.62 ± 1.23a 52.74 ± 1.20a 21.69 ± 0.35a 12.69 ± 0.18
2 77.07 ± 1.37a 36.54 ± 0.67b 20.20 ± 0.38b 11.04 ± 0.17
3 53.03 ± 0.85b 73.34 ± 0.78c 48.51 ± 0.49c 23.21 ± 0.41
4 54.04 ± 0.78b 60.77 ± 0.84d 40.79 ± 0.52d 21.24 ± 0.37
Each value is a mean (X ± SD) of triplicate samples
Note: Values in a row with different alphabets are statistically significant (P < 0.05; SNK test)
