The experiment was conducted to evaluate the productivity, profitability and adaptability of two up-graded dwarf chicken populations under smallholder farmers’ condition. A total of 72 birds of third generation (F₃) of Dwarf-Fayoumi (IDC♂ × Fay♀) and Dwarf-Leghorn (IDC♂ × WLH♀) at 12 weeks of age were distributed to 12 farmers nearby three villages (Kewatkhali, Boyra, Sutiakhali) of Bangladesh Agricultural University, Mymensingh. Birds were reared at farmers’ house for a period of 16 weeks with same feeding and management practices. Farmers were grouped into two (6 farmers in each group) for allocating IDC♂ × Fay♀ and IDC♂ × WLH♀ upgraded genotypes. Each farmer was given six birds of same genotype. The study revealed that IDC♂× Fay♀ pullets showed earlier sexual maturity (147.50±0.76 days) and lower feed intake (74.55±0.23 g/bird/day) and thus had a better FCR (2.98±0.02) during the experimental period. The corresponding values were found 169.83±1.35 days, 76.07±0.19 g/bird/day and 3.51±0.02, in IDC♂ × WLH♀ genotype. Moreover, among the production traits considered egg mass, hen day egg production, performance efficiency index and egg feed price ratio were found higher among the IDC♂× Fay♀ pullets as 25.07±0.20 g/bird/day, 37.48±0.43%, 21.22±0.95, and 1.175±0.015, respectively. The survivability of IDC♂ × Fay♀ and IDC♂ × WLH♀ upgraded genotypes were 94.4 and 77.7%, respectively during the experimental period. Therefore, it can be concluded that the IDC♂ × Fay♀ pullets were found more productive, profitable and had better adaptability than IDC♂ × WLH♀ pullets under smallholder farmers’ management. The resultant IDC♂ × Fay♀ upgraded chicken could be utilized as mini layer under rural settings of Bangladesh.</p> <p>Asian J. Med. Biol.
