Abstract: A total of 300 Oreochromus niloticus with an average body weight of 15±1 gm were used. The fish were randomly divided into 5 equal triplicate groups (20 fish/replicate). A basal control diet was formulated to fulfil the nutrients requirement of fish according to24) and contained 30.80% CP and 2940 kcal/kg DE. In other 4 experimental diets supplemented by pomegranate peel extract (PPE) at rate of 0.1, 0.2, 0.3 and 0.5 %. The fish were fed isonitrogenous, isocaloric diets 3 times daily at rate of 3% of body weight for 10 weeks. Results revealed that the growth performance of fish fed the experimental diets was decreased but none significantly (P>0.05). Also, results indicated that the lowest levels of cholesterol, triglyceride, LDLcholesterol, ALT, AST, creatinine and urea were found in fish groups fed on diets contained PPE, while these groups had a significant (P<0.05) increased HDL-cholesterol concentration. Some immunological parameters (IgM and lysozyme) were significantly improved due to supplementation of the PPE. These results indicate that addition of pomegranate peel extract (PPE) in Oreochromus niloticus diets without any adverse effects on growth parameters orhealth status. In addition, it improved immune status, lipid profile and functions of liver and kidney.
