Abstract:
An experiment was conducted in order to verify the “Effect of Selected Millets Combination in supplementary diet on Growth & Digestibility of Nile tilapia, Oreochromis niloticus (Linnaeus, 1758) Fingerlings”. Dietary supplementation of Pearl millet & sorghum millet (1:1) using a 0% (T₀), 5% (T₁), 10% (T₂), 15% (T₃), and 20% (T₄) inclusion rate 20% (T₄) were fed to fish @ 4% body weight twice a day morning and evening. In experiment total number of 200 Oreochromis niloticus fingerlings were used in 225 litres of volume in 20 FRP tanks of. 10 fishes distributed to one of 5 treatments (including the control) and with 4 replicates. During experimental period, Apparent protein digestibility (76.433±0.4695) of various treatments along with higher weight gain (42.48±0.0779 g), percent weight gain (85.811±0.4695) SGR (1.032±0.0042), GCE (0.366±0.0015) and lowest (best) FCR (2.729±0113) of Oreochromis niloticus fingerlings showed the highest value at 20% in treatment T₄ with a significant difference of (p<0.05) by using different levels of millets combination in fish diet. The results of the investigation demonstrated that adding millets to fish diets at a rate of 20% had a positive impact on Nile tilapia (Oreochromis niloticus) fingerlings on growth and digestibility.
