Formulation of Feed with Varying Dietary Contents to Determine their Effect on the Carcass Composition of Cyprinuscarpiocommunis Fingerlings

Abstract
Cyprinuscarpiocommunis fingerlings having average weight 1.64 g ± 0.13 and length 5.26 cm ± 0.10 were fed on four different formulated feeds (Feed A, Feed B, Feed C, Feed D) and a control feed @ 6% of their body weight, three times a day. Feed A, B, C and D were formulated using the ingredients like ground nut oil cake, mustard oil cake, rice bran, wheat bran, fish meal and soybean meal. The ingredients were selected so as to suffice the balanced need of protein and energy of the Common carp. The experiment was conducted in fiber glass tanks for a period of 90 days. The experiments comprised of four dietary treatments i.e. Feed A, B, C and D and a control, each in triplicate set. The initial carcass dry matter content of the fingerlings was recorded 24.18% ± 0.19.After 30 days, the carcass dry matter content of the fingerlings did not vary significantly (P > 0.05). After 90 days, the carcass dry matter content was recorded the highest (29.35% ± 0.14) in the fingerlings fed on Feed B and the least (28.18% ± 0.19) in the fingerlings fed on Feed C. The initial carcass moisture content of the fingerlings was recorded 75.82% ± 0.31. After 30 days, the carcass moisture content of the fingerlings did not vary significantly (P > 0.05). After 90 days, the carcass moisture content was recorded the highest (71.82% ± 0.13) in the fingerlings fed on Feed C and the least (70.65% ± 0.11) in the fingerlings fed on Feed B. The initial carcass crude protein of the fingerlings was recorded 18.43% ± 0.24. After 30 days, the carcass crude protein of the fingerlings did not vary significantly (P > 0.05). After 90 days, the carcass crude protein was recorded the highest (25.03% ± 0.12) in the fingerlings fed on Feed B and the least (21.54% ± 0.29) in the fingerlings fed on Feed C. The initial carcass crude lipid of the fingerlings was recorded 2.19% ± 0.12. After 30 days, the carcass crude lipid of the fingerlings did not vary significantly (P > 0.05). After 90 days, the carcass crude lipid was recorded the highest (4.30% ± 0.22) in the fingerlings fed on Feed B and the least (3.53% ± 0.19) in the fingerlings fed on Feed C. The initial carcass carbohydrate content of the fingerlings was recorded 1.43% ± 0.10. After 90 days, the carcass carbohydrate was recorded the highest (2.88% ± 0.13) in the fingerlings fed on Feed C and the least (2.42% ± 0.10) in the fingerlings fed on Feed B. The carcass carbohydrate content of the fingerlings did not vary significantly (P > 0.05) after 30 and 90 days of experiment. The initial carcass ash content of the fingerlings was recorded 2.58% ± 0.16. After 90 days, the carcass ash content was recorded the highest (5.59% ± 0.18) in the fingerlings fed on Feed B and the least (5.12% ± 0.22) in the fingerlings fed on Feed C. The carcass ash content of the fingerlings did not vary significantly (P > 0.05) after 30 and 90 days of the experiment. The initial carcass energy content of the fingerlings was recorded 7.67 Kcal/g ± 0.26. After 30 days, the carcass energy content of the fingerlings did not vary significantly (P > 0.05). After 90 days, the carcass energy content was recorded the highest (12.47 Kcal/g ± 0.19) in the fingerlings fed on Feed B and the least (10.24 Kcal/g ± 0.20) in the fingerlings fed on Feed C.
