Determination of proximate composition of fish feed ingredients locally available in Narsingdi region, Bangladesh

Abstract

The present study was carried out to determine the proximate composition of feed ingredients collected from local feed mill in Narsingdi Region during 21 March, 2015 to 25 August, 2015. The research was performed to qualify the nutrients (protein, lipid, carbohydrate) and to assess the content of ash and moisture. Proximate composition was determined on the homogenous basis. The percentage of protein in different feed ingredients ranged from 8.89±1.30-38.23±2.76. The highest protein content (38.23±2.76) was recorded from the dried fish and shell fish meal and the lowest value (8.89±1.30) was recorded from the maize. The percentage of lipid in different feed ingredients varied from 2.04±0.43-17.23±0.17. The maximum lipid content (17.23%) was found in mastered oil cake and the minimum (2.04±0.43) in wheat meal. From which ingredients it was found, the percentage of carbohydrate, moisture and ash were recorded (24.65±2.15-58.92±1.73), (7.00±1.88-13.20±2.67) and (13.25±1.32-20.27±1.56) respectively. The highest value of carbohydrate (58.92±1.73) was recorded from rice bran and the lowest value (24.65±2.15) was recorded from mastered oil cake. The highest amount of moisture (13.20±2.67) was found in crab shell and the lowest amount (7.00±1.88) was found in meat and bone meal. To maintain the optimum nutrient content and ultimately rapid growth in the aquaculture farms, the farmer should take proper initiatives for measuring the nutrients in feed usually offered in farms.
