Abstract

The study was carried out at Zam Zam poultry farm at Baradighir Par in Chittagong for a period of 02/08/2016 to 30/09/2016 to observe management of housing, feeding, lighting, production performance, and disease control practices of 5000 layer birds of Lohmann brown under open housing system. 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
