ABSTRACT
The research project was designed to check the effect of polyphenols supplemented canola meal-based diet on proximate composition, mineral absorption and hematology of Cyprinus carpio fingerlings. The diets were formulated in such a way that sufficient supply of all required nutrients were ensured for normal fish growth. Collection of feces from each tank was done twice a day. Impact of each treatment on the absorption of minerals, proximate analysis and hematology were determined using standard methods and formulae. Highest minerals absorption (Ca, Na, K, Fe, Cu, P, Mg and Al) was observed in the fish fed at 400mg/kg of polyphenols in canola meal based diets. Similarly, best hematological parameters (RBCs, WBCs, PLT, Hb, PCV, MCHC, MCH and MCV) as well as proximate composition (crude protein, crude fat, ash, moisture and carbohydrates) were noted in fish group fed on 400mg/kg of polyphenols in diet. Hence supplementation of polyphenols at 400mg/kg was found to be optimum for better hematology, minerals absorption and carcass composition of common carp.
