ABSTRACT
The poultry industry in Bangladesh has shown remarkable growth, significantly contributing to the economy and meeting the increasing demand for animal protein. This study evaluates the egg production performance of four commercial layer strains Hy-Line Brown, ISA Brown, Novogen Brown, and Bovans Brown under controlled housing conditions. Data were collected from Diamond Eggs Limited (DEL) and Protein House Limited (PHL), Kapasia, Gazipur, and analyzed. The findings revealed that the controlled housing systems effectively mitigated environmental stress, such as high temperatures and fluctuating humidity levels, which are known to adversely affect production and increase mortality rates. ISA Brown groups in Protein House Limited showed an average production rate that was 72% to 91%, while in Diamond Egg Limited, production rate of ISA Brown was 72% to 88%. Similarly, Hy-Line Brown groups demonstrated an average production range that was 74% to 83%. Results indicate that Hy-Line Brown and ISA Brown strains were performed better than others in terms of egg production under controlled conditions, highlighting their potential as sustainable choices for poultry farming in Bangladesh. Furthermore, the study confirms that controlled housing systems provide superior results compared to traditional housing.
