Abstract:

Two parallel experiments were conducted to evaluate the utilization of defatted and toasted soybean flour (SF) blended with poultry meat meal (PMM) as a dietary protein source in the practical diets of Oreochromis niloticus (M±SE = 19.4±1.8 g) fingerlings. They were fed four isonitrogenous and isoenergetic diets containing blends of SF and PMM in ratios of 25:75, 50:50, 75:25 and the reference diet (100:00) for eight weeks, at 4% body weight per day.
A trend of difference in nutrient utilization was observed in both investigations as diet II (50:50) recorded better food conversion ratio, specific growth rate, and protein efficiency ratio than any other diet. These differed significantly with the diets (P Carcass composition differed significantly with respect to the diets only in O. niloticus (P
