During study period, in case of brooding chicks, feed intake was 17gm/day in 2nd week, 19gm/day in 3rd week and 21gm/day in 4th week of age. Body weight was 56gm, 115gm, 187gm, 238gm respectively at 2nd, 3rd, 4th, 5th week of age. The average body weight gained was 60.67 gm/week. The mortality rate was 0.123% per week. In case of layer, the body weight was observed to be 1.87kg, 1.89kg, 1.94kg and mortality was 0.073%, 0.044%and 0.048% respectively at 33rd, 34th, 35th week of age and average feed intake was 115.79gm/day. As for the hens, per day egg production was 87.27% from 33rd to 35th week of age. The peak production was observed to be 88.18% at 33rd week of age. The mortality was 0.055% per week and total mortality was 0.17% over the total experimental period. It may be concluded that, peak production can be achieved during 33rd week of age
