Effects of dietary supplementation of date palm (Phoenix dactylifera) seed extract on body composition, lipid peroxidation and tissue quality of common carp (Cyprinus carpio) juveniles based on the total volatile nitrogen test.

Date palm seed (Phoenix dactylifera) (DPS) extract has been used worldwide in pharmaceutical agent due to its constituents. This study aimed to assess the effects of DPS extract as a dietary supplementation at on the body composition, lipid peroxidation and tissue quality of common carp (Cyprinus carpio) based on the total volatile nitrogen (TVN) test. Common carp juveniles weighing ca 32 g were cultured in 26°C freshwater for 60 days and fed with diets supplemented with 0.5%, 1%, 2% and 4% of DPS extract. At the end of the trail, the crude protein (p>0.05) and crude lipid (p
