Cyprinus carpio was fed on different types of plant and animal feed to study its food utilization and energy budget. Amongst the plant diet, the rate of maximum consumption, absorption and metabolization of food was recorded in Vicia faba (5.31 ±1.20; 2.76 ±2.70 and 2.56 ±0.15) respectively. Maximum food conversion rate was noted in Amaranthus spinosus (0.30 ±0.03). Whereas in animal diet, it was egg white (9.66 ±0.90; 7.22 ±1.02 and 7.21 ±0.08) respectively. Maximum food conversion rate was observed in Brassica oleracea (1.00 ±0.21) with respect to overall energy budget. With reference to the overall energy budget in relation to weight and time, maximum consumption in Vicia faba (0.17 ±0.04), absorption in Brassica oleracea (0.65 ±0.07), metabolization and conversion of food in Amaranthus spinosus (0.56 ±0.00 and 0.01 ±0.00) was observed among the plant diet. Whereas in animal diet, maximum consumption, absorption and metabolization of food was noted in egg white (0.32 ±0.03; 0.24 ±0.03 and 0.24 ±0.00 respectively) and conversion rate in bloodworm (0.03 ±0.00). Egg white provided the maximum overall energy budget. Studies of such sort are essential as it portrays the bioenergetics schemes in Cyprinus carpio.
