Abstract:
A 90 day study was undertaken to establish an optimum inclusion level of some plant and animal protein-rich feed resources in a formal least-cost diet for African catfish (Clarias gariepinus) fingerlings using linear programming technique. Five isonitrogenous (35% CP), isocaloric (3000 kcal kg-1) and isolipidic (6.00% lipids) diets were formulated. The reference diet (DT01) was formulated using Fishmeal (FM), White Maize Meal (WMM), Dried Brewer’s Grain (DBG), Palm Kernel Cake (PKC) and salt while Duck Weed Meal (DWM), Soybean Meal (SBM), Blood Meal (BM) and Shrimp Waste Meal (SWM) where included in diets DT02, DT03, DT04 and DT05, respectively. The formulated rations indicated that DWM, SBM, BM and SWM can be optimally included in a formal least-cost diet at 30.85, 30.75, 13.69 and 17.14% levels replacing 12.5, 72.14, 69.67 and 72.14% FM leading to 17.18, 23.00, 34.11 and 21.19% formula cost reduction. Ration formulated were tested on catfish fingerlings (20.15±3.50 g) twice daily for 6 days a week in triplicate groups of experiments earthen ponds for growth performance and feed utilization. Result show that growth performance and feed utilization parameters were not significantly (p>0.05) different from the RD and among the treatments. Carcass composition of the experimental fish showed that all the fish fed the experimental diets had higher carcass protein and lipid contents and lower ash and nitrogen free extract contents than the initial fish sample. These values are however similar for all treatments. These results show that locally available plant and animal protein-rich feed resources can be included in a formal catfish diet at cheaper costs without any negative effect on growth.
