ABSTRACT
This study aimed to examine the influence of additional soybean oil with different levels in feed commercials on Pangasius djambal for survival rate, feed efficiency, and growth performance. The research experiment was conducted as a complete random design with five groups: (A) feed commercial without additional soybean oil, (B) feed commercial with additional soybean oil 2%, (C) feed commercial with additional soybean oil 4%, (D) feed commercial with additional soybean oil 6%, and the last group (E) feed commercial with additional soybean oil 8%. Triplicate groups of 100 fish per tank, with an initial mean weight of 23.05 ± 5.8gr and an initial mean length of 11.49 ± 4.3 cm, were fed twice a day for eight weeks. Feeding is based on 4% fish biomass in the first four weeks and 3% in the last four weeks. The survival rate, specific growth rate, feed conversion rate, and feed efficiency showed no significant effect (P>0.05). In conclusion, this study showed that adding soybean oil to various levels in the diet of commercial fish resulted in a survival rate of 94.67 ± 6.85 to 99.67 ± 0.47%, growth did not make a difference between all experiments, and feed utilization was 78. 96±8.12 to 85. 65±6.86%.
