Abstract:
A 60 days feeding trial was carried out to find out the impact of pearl millet (Pennisetum glaucum) mixed feed on the growth performance of fingerlings of Cyprinus carpio var. communis (Linnaeus, 1758). Experimental diets were formulated by adding pearl millet flour substituting an equivalent proportion of rice bran in the control diet at five different levels i.e., T₁ (06%), T₂ (12%), T₃ (18%), T₄ (24%), T₅ (30%), and T_0, (control) viz., without adding pearl millet. The fish were fed at a rate of 3% of their body weight once a day. The pearl millet mixed feed has not shown any detrimental effects on the fish survival, growth, and water quality parameters. The maximum net weight gain was 23.60±0.15 g noticed in T₄ at 24% inclusion of pearl millet, and the lowest was (21.43±0.03 g) in T₀ (control). The in this treatment level (T^­₄) the highest percent weight gain (54.89±0.34%). The lowest FCR (2.70±0.01). The maximum SGR (0.98±0.003%). However, the maximum GCE was noted in T₂ (0.36±0.003) compared to minimum (0.35±0.001) value in T₀ (control). Including of pearl millet at 24% inclusive level & equally replacing the rice bran gave with apparent protein digestibility in common carp.
