A total of 3.429 Tam Hoang breeder hensaged 25-32 weeks were used in this study to evaluate the production performance and egg quality at the present time - with the influence of new breeds. The birds were kept in a closed house, with the density of 0.33 m2/bird and the male:female ratio of 1:8. The results showed that there were statistically significant differences (Pproduction performance such as laying rate (49.93-60.81%), egg weight (51.3-54.98 g/egg), feed intake (143.24-176.09 g/bird/day), feed conversion ratio (2.79-3.24 g feed/g egg), percentage of double-yolked eggs (0.65-0.86%) and percentage of abnormal eggs (1.23-1.60%). The parameters of egg quality also showed that there were statistically significant differences (Pyolk index (0.41-0.47), albumen index (0.01-0.08) and Haugh unit (71.90-89.27). These findings provide updated information about the production performance and egg quality of Tam Hoang breeder chickens, laying the foundation for further research and orienting chicken production.
