Item Open Access Molecular Analysis and Bioinformantics(ebonyi state university repository office, 0028-11-28) biotechnology research and development centreItem Open Access NUTRITIVE VALUE OF THE MAJOR COMMERCIAL FISH FEEDS IN USE BY FISH FARMERS IN EBONYI STATE(EBSU REPOSITORY OFFICE, 2023-02-15) Agwu, S. C1*., Ogbanshi, M. E2 ,Oko, A. O3 .,Afiukwa, C. A3 ., Ominyi, M. C3 and Nwali, B. U2Gainful fish farming depends largely on imported fish feeds which is targeted at providing the aquaculture fishes with balanced diet for both fast growth and early maturity. The feed are in form of pellets of different sizes and their cost in aquaculture enterprise represents about 70 % of the total cost of fish farming. Protein waste and higher ammonia production constitute imbalanced protein and carbohydrate contents in fish feeds which cause low water quality and growth, respectively. The information on the nutritive contents, as stated by the manufacturers of commercial feeds on their labels, are often not reliable and misleading to the farmers. This study assessed the nutritive contents of these feeds which will help the fish farmers in making informed decisions on the type of feed they purchase in Ebonyi State. The fish feed samples were in six groups (A, B, C, B, E and H) where group A is locally formulated (control). The protein contents (%) of feed B(53.8) > E(48.9) > D(48.7) > C(45.9) > H(35.9) > A(16.8) ,respectively, with B and A being significantly different (P<0.05). Fat contents (%) of D(6.3) > B(4.4) > E(3.8) > C(3.4) > H(1.8) > A(1.2), respectively, with D being significantly different among feeds (p<0.05). The carbohydrate contents (%) for feed A (66.3) > H (49.5) > C (39.6) > E (36.2) > D (31.04) > B (27.8), respectively. Feed A contains the highest moisture content (p<0.05) while the Fiber contents of the feeds did not show any significant different (p>0.05) the feeds are high in Magnesium, Calcium, Sodium and Potassium (p<0.05) while there is no significant differences for the Zinc, Iron and Phosphorus (p>0.05) content in the feeds
