Abstract
In this research five feed ingredients were selected for the experiment entitled effect of dietary inclusion of Leucaena leucocephala on the growth performances of Nile Tilapia, which were Soybean meal, Rice bran, Mustard oil cake, Wheat flour and Leucaena leaf meal. Five treatments were T1 which was control in which no Leucaena leaf meal was used, T2 in which 10% replacement of Soybean meal was done by LLM, T3 in which 20% replacement was done and 30% and 40% replacement was done in T4 and T5 respectively and in each aqauarium 10 fingerlings were stocked. During the research, water quality parameters like temperature, pH and DO was measured in daily basis and Ammonia was measured in weekly basis. After three month of research, significantly the maximum weight gain was obtained in treatment 2 (52.48 g), followed by treatment 3 (143.60 g) and minimum weight gain was obtained in treatment 5 (129.14 g) followed by treatment 4 (130.17 g). Treatment 2 shows the highest average daily weight gain (0.116 g), followed by treatment 3 (0.110 g). Lowest average daily weight gain was observed in treatment 4 and 5 (0.09 g). Treatment 2 shows the highest Specific growth rate (SGR) value (1.30), followed by treatment 3 (1.22). Similarly, in treatment 4 and 5 the lowest SGR value (1.11) and (1.10) was obtained respectively. Lowest Feed Conversion Ratio (FCR) was obtained in treatment 2 (2.64) followed by treatment 3 (2.71). Highest FCR value obtained in treatment 4 (2.96) followed by treatment 5 (2.94). Comparatively treatment 2 shows the better growth performances than other treatments.
