The growth response and hepatosomatic index of milkfish (<i>Chanos chanos</i> Forsskal) fed with diet various levels carbohydrates in fermented of cow rumen liquid

One effort to reduce the role of protein as an energy source in feed is maximize use carbohydrates and engineering optimization utilization can be done by adding exogenous digestive enzymes feed. This study aims determine level after being given cow rumen liquid which gives best growth response hepatosomatic index milkfish. was designed using a completely randomized design (CRD) consisting 4 treatments 3 replications, Thus, there are 12 experimental units. The were feeding with different levels carbohydrate feed, namely 27,81; 39,50; 46,97 56,75% mixed 80 mL per 100 g Feed juvenile milkfish measuring 7.19±0,036 kept recirculating aquarium density 15 fish/45 L brackish water. provision various had effect (α<0.05) on relative survival but no (α>0.05) Statistically, found fish fed carbohydrate-level treatment 46,97%.
