Abstract: A study was conducted to evaluate the effects of feeding 5 different crude protein (CP) and metabolizable energy (ME) levels with constant ME:CP ratio on performance of indigenous Hansli birds under intensive system of management. The different dietary treatments consisted of 14% CP and 2275kcal/kg ME in T1, 15% CP and 2437.5kcal/kg ME in T2, 16% CP and 2600kcal/kg ME in T3, 17%CP and 2762.5kcal/kg ME in T4 and 18%CP and 2925kcal/kg ME in T5. Results indicated that mean body weight as well as body weight gain were not significantly (p>0.05) affected across treatments except for 40th and 45th week of age, where birds fed high CP and ME diet had significantly (p<0.05) higher bodyweight. There was significant (p<0.05) reduction in feed intake with increase in CP and ME level of diet. But CP and ME intake during the experimental period did not differ significantly (p>0.05) between the treatment group. FCR was significantly improved with increase in CP and ME of diet. The PER and EER values followed a similar trend. The age at lay of first egg was 221.33 days in T1 which was significantly (p<0.05) higher than all treatment groups. The highest peak egg production of 58.34% (HDEP) was achieved in T2 (15% CP and 2437.5kcal/kg ME) that was significantly (p<0.05) higher than all other treatment groups. There was no significant (p>0.05) difference in fertility among any treatment groups. Fertility was found to be in range 72.86±4.67% to 85.74±3.47%. Similarly no significant (p>0.05) difference among treatment groups was found for hatchability on FES basis. But a significant (p<0.05) difference was found on hatchability on TES basis, in which T2 group had higher hatchability (84.80±2.05%) as compared to other treatment groups. The egg weight of treatment groups from 30th to 45th week of age ranged from 38.67±0.67g to 48.33±0.45g and was not influenced by dietary treatment. Period had a significant effect on egg weight and with advancement of age, egg weight increased. The internal quality of egg i.e albumin height(mm), albumin width(mm), albumin index(%), yolk height(mm), yolk width(mm), yolk index(%), haugh unit(HU), specific gravity, albumin weight(g), yolk weight(g), albumin(%), yolk(%), yolk albumin ratio of all treatment group was found to be similar (p<0.05) and not influenced by the dietary treatment groups. From the results of the experiment it is concluded that’s a layer diet with 15% CP and 2437.5kcal/kg diet is sufficient to obtain optimum egg production in Hansli hens without adversely affecting the egg quality traits
