Inheritance of growth and production traits in Gramapriya male line chicken

A comprehensive study was carried out in Gramapriya male line (PD-6) chicken with respect to growth, production and egg quality traits utilizing the data generated from 1995 chicks 230 hens S-8 generation at ICAR-Directorate of Poultry Research, Hyderabad, Telangana. Highly significant differences among hatches were observed for body weight, shank length, age sexual maturity (ASM), (EP), weight (EW) mass (EM). The least squares mean weights (BW) 2, 4, 6, 20 40 weeks 187.03±0.97, 499.74±1.58, 838.67±5.69, 2074.93±9.82 2891.26±15.25 g, respectively. lengths 4 6 70.19±0.09 87.48±0.12 mm h2 length six 0.31±0.06 0.23±0.05, respectively, which moderate high magnitude.
