A study on the management and production performance of the layers available in the Lohagara Upazila, Chittagong

Abstract

The study was conducted to observe the management and production performance of two different layer strains (Hisex and ISA Brown) available in Lohagara, Ctg., under cage rearing system. Collected data on the egg production percentage, body weight gain and feed intake of observed layer birds of the farm were compared with the standard level. The production performance was compared of laying period under normal management in cage system. The egg production was found to be highest in Hisex brown (84%) compared to ISA brown (83%). The egg weight of Hisex brown was (55gm) which is higher than ISA brown (53gm). The feed consumption rate was also higher in ISA Brown brown (125gm) per bird during peak production but it was lower in Hisex brown (120gm) per bird during the same stage of production. Average age at peak production was 26 weeks in Hisex brown, where as 28 weeks was in ISA brown. Average length of peak production 10 weeks was in Hisex brown and 8 weeks was in ISA brown. In the present study, it was noted that some production parameter were slightly lower than literature supplied by respective company, but general production performance of Hisex Brown was better than ISA brown under normal management in cage system.
