Efficacy of Dietary Chenopodium album Extract on Some Health Parameters, Digestive Enzymes and Growth Performance in Juvenile Cyprinus carpio

Abstract

The present study was conducted to investigate the efficacy of Chenopodium albumaqueous methanolic extract supplementation on the immunological and haematologicalindices, digestive enzyme activity and growth performance of the common carp (Cyprinuscarpio). C. album was added to a basal diet at the rate of 0 (CA0), 0.01 (CA0.01), 0.05(CA0.05) and 0.1 g kg−1 (CA0.1), and C. carpio was fed this diet for 45 days. Respiratoryburst activity was significantly increased in all experimental groups on days 15 and 30compared to the control (P < 0.05). Lysozyme activity was significantly increased over allsampling times compared to the control except in CA0.1 (P < 0.05). Myeloperoxidaseactivities were significantly increased in all experimental groups compared to
