Dual type colour hens were evaluated for performance traits during pre summer (92.40F to 100.30F, average 95.30F) and post summer (101.70F to 106.30F, average 104.60F) periods, feeding P1(15%.CP), P2(16.5%.CP) and P3(18%.CP) protein diet with ascorbic acid (250mg/kg) supplementation. Feed intake/hen/day and egg production/hen/period was significantly higher (P<0.05) in P2 than P1and P3 during both summer periods. Egg weight of P2 and P3 was non significant in pre summer whereas during post summer, P2 egg weight was significantly higher than P1 and P3. Feed efficiency/kg egg mass in P2 and P3 was non significantly different and significantly better than P1. During post summer feed efficiency (FE) improved significantly (P<0.05) with increasing protein levels. Feed Intake (FI), egg production (EP), egg weight was decreased in post summer than pre summer in the range of 13.64% to 23.28%, 5.28% to 12.81% and 2.71% to 6.25% respectively. An adverse effect on FI was higher, followed by egg production than egg weight. FE improved in the range of 3.78% to 9.17% shown higher improved in P3 high protein diet. Ascorbic acid supplementation (250/mg/kg) significantly improved FI and EP in both summer period, Egg wt in pre summer and FE in Post summer period. Treatment P2XC1 has higher feed intake, egg production, egg weight and feed efficiency/ kg egg mass during pre and post summer period.
