STUDY ON PRODUCTION PERFORMANCE OF ISA BROWN STRAIN AT KRISHIBID FIRM LTD., TRISHAL, MYMENSINGH

The study was conducted on a commercial layer farm at Trishal Upazilla on a village side area to observe the production performance of ISA Brown layer strain. 6000 ISA Brown layer strain were studied on the farm. All of the birds were reared in cage management system. The average egg weight, hen day egg production, average feed consumption per day, feed conversation efficiency of the ISA Brown in the cage management system at Krishibid farm Ltd. Trishal, Mymensingh were studied. The hen day egg production was 77.16±17.33 (%), feed conversion efficiency was 4.37±10.26, average egg weight 61.45±4.11 g and the average feed consumption was 116.47±7.47 g per bird per day. The above findings of the present study were near about similar to the recommended production level of Hendrix Genetic Company, France, 2006, except hen day egg production. The hen day egg production was slightly lower than that of the recommended production level. It may be due to management and climatic effect on birds. Finally it is recommended that ISA Brown layer strain in adaptable and profitable for Bangladesh.
