| Abstract | Tamarind seed, a by-product of tamarind paste production, contains usable nutrients in the kernel that could induceimmunity in rats. This study aimed to determine the possibility of using tamarind kernel powder in red tilapia feed observing itseffects on fish growth and immunity. A feeding trial was conducted using tilapia fingerlings fed with 1, 2.5 and 5% tamarindkernel powder (TKP) inclusion in feed for eight weeks. A control group were fed with diet without TKP. The average initialweights of the red tilapia ranged from 4.73 ยฑ 0.10 to 4.87 ยฑ 0.23 g/fish (P>0.05). Growth parameters were monitored during thefeed trial. At the end of the trial, lysozyme activity was determined, and fish were subjected to a pathogen challenge byintraperitoneally injecting them with 1.6 x 108 CFU Aeromonas hydrophila. Results showed that the fish reached 29.07 ยฑ 2.96 to30.77 ยฑ 2.05 g/fish sizes. The growth parameters (weight gain, ADG, FCR), blood counts, and hematocrit were not significantlydifferent among the treatments (P>0.05). The lysozyme activity also showed no significant difference among the treatments (21-28 units/milliliter). Fish mortality rate post-challenge with pathogen was not significantly different between control andtreatments (P>0.05). The results showed that 5% tamarind kernel powder could be included as a binding agent in feed withoutaffecting growth of tilapia during the nursery stage. |
