Abstract

The present study was carried out to investigate the impact of substituting  soybean meal with slaughterhouse poultry by-products meal on the Nile tilapia composition, mineral content, apparent digestibility co-efficiency, and basil yield composition under aquaponics system conditions. In an 84-day feeding experiment and 30-day digestibility trial, three isonitrogenous and isocaloric diets (control, SPBM50%, and SPBM100%) were formulated to contain 30% CP. As result, neither the carcass content of moisture nor the CP was affected by the experimental diets. On the other hand, the fish fed SPBM100% content showed high significant ash content, while those fed SPBM50% content recorded high significant EE and GE contents. The differences were notably not significant among the different treatments. The fish group fed SPBM50% diet recorded significantly higher concentrations of minerals than those fed control and SPBM100% diets. The concentration of heavy metals in fish muscles was within the permissible limits for human health protection. The SPBM50% treatment recorded the highest levels in DM, CP, EE and CF contents. No significant difference was observed in ADC of DM, CP, CF, NFE, and GE kcal/g (%) in fish fed the experimental diets. The ADC of EE content of diets was higher in the SPBM100% diet that exhibited significant differences with the control treatment. In conclusion,  the SPBM100% has a positive effect on basil composition under aquaponic system conditions as a good source of minerals that are more available, Moreover,  it has  no impact on the accumulation of heavy elements in fish muscles.
