| This study determined the effect of different shrimp head meal (SHM) levels (0, 5, 15, 25 and 30%) in practical diets for Caribbean white shrimp juveniles Litopenaeus schmitti (0.29 ± 0.0025 g). A totally randomized experimental design was carried out under laboratory conditions during 54 days. There were no significant differences (p > 0.05) in survival of shrimps in all treatments evaluated. This result indicated that SHM included at 5, 15 and 25% in diet promoted growth. The relation of SHM inclusion level in diet with final weight (FW), food conversion rate (FCR) and protein efficiency ratio (PER) were described by the following quadratic equation: FW = 0.8023 + 0.0604 S - 0.0018 S2, 2 =0.81; FCR = 8.0019 - 0.6081 S + 0.0164 S2, R2 =0.82 and PER =... |
