Effect of Poultry Hatchery Waste Meal supplemented with Clove basil leaf, Ocimum gratissimum as Replacement for Fish Meal on Growth Performance of Clarias gariepinus (Burchell, 1822)

Abstract

Abstract

This study was carried out to investigate the graded level replacement of fish meal with poultry hatchery waste meal supplemented with Ocimum gratissimum leaf on growth performance of Clarias gariepinus juvenile. The fish were divided into 7 groups of 15 juvenile (10 ±0.03g) in three replicates. The fish were fed with diets containing 0, 25, 50, 75 and 100% poultry hatchery waste meal as replacement for fish meal, Ocimum gratissimum was included at 2% in all the treatment except treatments 6 and 7 with Hatchery waste only which served as control groups with 100% fish meal and hatchery waste with no inclusion of O. gratissimum respectively. The highest weight of 0.39gm, protein efficiency ratio 0.01 and feed conversion ratio of 1.75 were found in fish fed with diet containing 75% poultry hatchery waste and 2% Ocimum gratissimum in T4, which was significantly (p<0.05) higher than those fish fed with other treatments and control diets. The present results suggested that replacement of fish meal with poultry hatchery waste meal and O. gratissimum supplementation up to 75% could improve growth and feed utilization of Clarias gariepinusfingerling.
