Nutritive potential of plantain peel meal and replacement value for maize in diets of African Catfish (Clarias gariepinus) fingerlings. (488)
This study was carried out to evaluate the potential of plantain peel meal as a replacement for maize in the diet of Clarias gariepinus. Triplicate groups of fish were fed five diets which were formulated to contain graded levels of plantain peel meal replacing 0, 25, 50, 75, and 100% of maize. The feeding trial lasted 12 weeks. The results showed that the diets significantly (P < 0.05) affected fish performance. Percentage weight gain (PWG) was 602% in fish fed the control diet (without plantain peel meal). A consistent decrease in PWG with increase in plantain peel meal was observed, with PWG at 222% in fish fed the diet with 100% supplementation of maize with plantain peel meal. Protein efficiency ratio (PER) and protein productive value (PPV) were reduced with increasing content of plantain peel meal. Least carcass protein (13.4% wet weight) was observed for fish fed the highest plantain peel meal level and there was a steady significant increase in carcass protein with decrease in plantain peel meal. The data indicated that C. gariepinus did not favourably tolerate diets containing high levels of plantain peel meal.
