Abstract

A total of 29460 ISA Brown commercial layers were force molted with feed restricted (20g to 70g) forced molting method to assess the effects of molting of ISA Brown commercial layers at Valuka Layer Farm-1, C.P. Bangladesh Co., Ltd. Layers were forced molted between 73 to 76 weeks of age. Forced molting made significant differences on egg production. Egg production (77.11%) and egg weight (66.93g) were increased in post molting period than that in pre molting (67.26%) and molting (22.27%) period. The value of egg weight in pre molting period was 65.51g and molting period was 58.25g. During molting period body weight loss was 193.75g. Whereas, in pre molting and after molting period body weight gain were11.25g and 11.00g respectively. Feed conversion (FC) was significant at 1% level of significance (P<0.01).  FC was better in post molting period (2.24), moderate in pre molting period (2.67) and worst in molting period (3.33). Mortality was slightly increased in molting period (0.21%) than that of pre molting (0.13%) and post molting (0.13%) period. The result of this experiment may be used to maximize egg production and egg weight in laying hens.
