| Abstract | ||
| This research was carried out to evaluate the effect of copra meal (Coconut oilcake) as a partial replacement of soybean meal on the growth and survival rate of the Nile tilapia (Oreochromis niloticus) fingerlings. Four treatments (T1, T2, T3, and T4) were designed, each with three replicates. Copra meal was used to replace soybean meal at different inclusion levels: 0% in T1 (control), 25% replacement in T2 (7.5% copra meal in the diet), 30% replacement in T3 (9.0% copra meal in the diet), and 35% replacement in T4 (10.5% copra meal in the diet). Water quality parameters were within the acceptable range during the study period. Final weight (g), weight gain (g), percent weight gain (%), feed conversion ratio (FCR), specific growth rate (%/day), protein efficiency ratio (PER) and daily growth co-efficient (DGC) varied from 14.11 to 18.92g, 12.47 to 17.28g, 760.36 to 1053.35%, 1.34 to 1.89, 4.3 to 4.89, 2.69 to 1.88 and 0.25 to 0.35, respectively. According to the results of the current study, 35% replacing of copra meal/kg (10.5% used in diet) in place of soybean meal resulted in the best growth performance and survival rate of tilapia. | ||
