| Abstract: | Cross-breeding of Gansu Yellow Chicken and commercial egg breed of Yaffa was conducted and its Yellow hybrid was evaluated in terms of its egg production, feed-egg conversion rate, Survival percentage and culling weight at 300 days of age. The test showed that with a culling weight as nearly 2.0 kg, the Yellow hybrid gave a more egg production and higher survival percentage by 10.33 % and 7.78 % respectively compared to those of Gansu, yellow checken, while its feed-egg conversion rate was 0.39 lower than that of Gansu Yellow chicken. |
