A CASE STUDY ON THE PRODUCTION, MANAGEMENT SYSTEM, BIOSECURITY AND HATCHERY MANAGEMENT SYSTEM OF BROILER PARENT STOCK (COBB-500) UNDER CONTROL HOUSING SYSTEM OF BRAC POULTRY FARM AT SREEMONGAL UNDER MOULVIBAZAR DISTRICT.

Abstract

The study was conducted to assess the management practices, production performances and hatchery management of broiler parent stock (Cobb-500) under control housing system at BRAC Poultry Farm & Hatchery Ltd. at Sreemongal, Moulvibazar. The study was undertaken with 27,000 broiler parent stock (Cobb-500). Result related with the average body weight gain at starter stage (0-5 week), grower stage (6-18 week), pre-breeder stage (19-23 week) and breeder stage (24th week - end) of Cobb-500 female birds was 601 gm, 1976 gm, 3045 gm and 4157 gm respectively. Similarly in Cobb-500 male birds it was 847 gm, 2515 gm, 3570 gm and 4972 gm respectively. Achieved average flock uniformity (0-65 week) of male and female birds was 81% and 80% respectively. The hen day egg production of the flock was 81%, 83%, 80%, 61.33%, 53.8% and 53.3% per week respectively at 24-38, 29-32, 33-40, 41-45, 46-55 and 56-60th week. The hatchability of eggs was observed in this farm was 78.33%, 80.42%, 880.97%, 78.61%, 78.68% and 71.85% per week respectively at the age of 24-28, 29-32, 33-40, 41-45, 46-55, 56-60th week. Overall mortality of the flock was below0.2% per week. It may therefore be inferred that Cobb-500 broiler parent stock performs well under control housing system in our country.
