Chemical Analysis and Nutritional Assessment of Defatted Garcinia Mangostana Seeds Used as an Additive on the Feed of Fish (Clarias Gariepinus)

Abstract

Chemical analysis and nutritional assessment of defatted Garcinia mangostana seeds DGMS were undertaken to determine its suitability as an additive at 0 00g 18 00g 36 00g 54 00g and 72 00g inclusion levels in diets and performance of Clarias gariepinus post juveniles Proximate analysis of DGMS showed that the defatted seeds were high in carbohydrate 71 00 0 79 but low in protein content 8 10 0 22 The mineral element analysis detected different minerals with potassium as the highest 270 00ppm All the fish increased in weight and length significantly p 0 05 above the initial values though no significant differences were observed among treatments at 49days in all growth indices showing that the diets were similar in nutritional qualities and adequate for growth of fish Hematological analysis showed increments in the final blood parameters at day 49 except MCH MCV and heterophils and very high levels of leucocytes and platelets p 0 05 No significant differences were observed in the haemoglobin content AST ALT globulins and albumin in fish on DGMScontaining diets Histology showed sub mucosal congestion in gill 36 00g DGMS severe interstitial congestion in kidney 72 00g DGM and vacuolations in liver in all groups except diet 4 54 00g DGMS and control 0 00g DGMS However higher survival rates were observed in all DGMScontaining diets than the control
