The present study was conducted to characterize Ghagus, a native breed of chicken for production, adaptability, semen and egg quality traits in comparison with PD4 birds. Sex wise body weight and shank length of Ghagus birds recorded at 40 weeks of age were significantly lesser than those of PD4 birds. Ghagus birds had significantly higher tonic immobility (TI) duration and asymmetry of shank length than those of PD4 birds but no differences were observed for number of attempts to induce TI and asymmetry of shank width and middle toe length. Mean shank width and middle toe lengths were significantly higher in PD4 birds. Ghagus birds produced significantly lesser number of eggs up to 40 weeks of age with smaller egg size. With respect to semen quality traits, Ghagus roosters had significantly better appearance and concentration of spermatozoa than PD4 birds. Study of egg quality traits revealed significantly better albumen index in Ghagus as compared to PD4 birds. However, significantly higher egg weight, yolk, albumen and shell weights were observed in PD4 birds as compared to Ghagus breed with no significant differences in other egg quality traits. The study indicated that, there is a scope for improvement of this important native chicken breed for growth and production traits as semen and egg quality traits were at desirable levels.
