abstract
The present study was conducted to determine the proximate composition of fish feed ingredients locally available in Narsingdi Region. In this study protein, lipid, moisture, ash, carbohydrate concentrations was assessed in rice bran, maize bran, wheat bran, mustard oil cake, soybean meal, DORB, meat and bone meal, mixed of oyster, shrimp shell and crab shell. Proximate composition was determined on the homogenous basis. The quantity of protein in different fish feed ingredients ranged from (12.04±1.30-47.23±0.61)%. Maximum amount of protein content (47.23±0.61)% was recorded from the meat and bone meal and minimum amount (12.04±1.30)% was recorded from the maize bran. The concentration of lipid in different feed stuffs ranged from (2.5±0.37-18.5±1.1)%. The highest value (18.5±1.1)% of lipid content was found in soybean meal and the minimum (2.5±0.37)% was recorded in Crab shell. Moreover, the value of moisture and ash were recorded (5.00±0.88-13.28±1.46)% and (7.43±0.12-22.55±1.32)% in the locally found feed respectively. The highest value of moisture (13.28±1.46)% was recorded from crab shell and the lowest value of moisture (5.00±0.88)% was recorded from meat and bone meal. The highest amount of ash (22.55±1.32)% was also found in meat and bone meal and the lowest amount of ash (7.43±0.12)% was found in maize bran. And finally last the concentration of carbohydrate in different feed stuffs ranged from (15.67±0.5-66.77±1.13)%. Maximum amount of carbohydrate content (66.77±1.13)% was recorded from the maize bran and minimum amount of carbohydrate content (15.67±0.5)% was recorded from the soybean meal.
