Abstract
A crossbreeding experiment between Hilly, a locally adapted chicken type in Bangladesh and Fayoumi, an egg type light chicken breed was carried out to evaluate phenotypic performances and to estimate genetic parameters for body weight and egg production at sexual maturity. Results show the mean hatch weight of Hilly♂ × Fayoumi♀ (H♂×F♀) crosses was 35±0.1 gm. In this study, H♂×F♀ crossbred showed a heavier body weight (1551± 32.0 gm/bird) at 20 weeks in comparison with other indigenous chicken genotypes in Bangladesh. The highest body weight gain was found in 8-10 weeks of age. H♂×F♀ crossbred hens exhibited sexual maturity at an average age of 147.5±1.6 days with an average body weight of 1350± 16.8 gm/bird. The mean weight of eggs at sexual maturity was 33.7±0.5 gm/egg. The estimates of heritability for body weight were ranged from 0.15 to 0.26. We observed a positive genetic correlation between weight at sexual maturity (WSM) and egg weight at sexual maturity (EWSM), meaning that hens with high weight at sexual maturity would produce heavier eggs.Asian J.

Highlights
Chicken constitutes 71.5 % of Bangladesh’s total livestock population with a census size of 268.3 million (Bhattacharjee and Khatun, 2016)
The aim of this study was to estimate phenotypic and genetic parameters for body weight, performances related to sexual maturity and early egg production traits to understand which traits should be included in breeding programs for this crossbred chicken
Performance of Fayoumi chickens In this study, Fayoumi chickens were observed to be sexually mature at the mean age of 155.80 ± 0.80 days under intensive floor management system
Summary
Chicken constitutes 71.5 % of Bangladesh’s total livestock population with a census size of 268.3 million (Bhattacharjee and Khatun, 2016). Fifty percent of the chicken populations in Bangladesh are raised in the backyard farming system This backyard poultry production yet contributes largely to the income of low-input rural farmers. Backyard poultry remains an important source of the rural nutrition as they can provide a regular supply of meat and egg. till to date, the production performance of the native chicken in Bangladesh is nominal. The native chicken population in Bangladesh comprises non-descript Deshi, Aseel, Naked Neck, Hilly and Red Jungle Fowls (Bhuiyan et al, 2005). These breeds/types are well known for their disease resistance and lower nutritional requirement (Barua, 1990). An exotic egg producing chicken breed can produce 140-159 eggs/egg under intensive management
