Development and Utilization Status

Big-bone chicken is a local chicken breed that is well-known both at home and abroad for both meat and eggs. It is famous for its large body, large eggs, delicious meat and rich nutrition. . It can be hybridized with many excellent local chicken breeds at home and abroad, and the production performance is greatly improved. Introduce the cross between Ankahong (as the male parent) and the big-bone chicken (as the female parent), a fast-growing broiler breed with high feed return, to build a two-line hybrid breeding system. The average weight of hybrid chickens is greater than that of large-bone chickens, and their weight exceeds the average of both parents, showing significant hybrid vigor. The survival rate of hybrid chickens is higher than that of Anka red chickens, which shows that hybrid chickens have zero advantage in terms of viability. In a reciprocal cross between large-boned chickens and Sichuan Mountain Silky Chickens, the egg production, growth rate and meat traits of the hybrid group were significantly higher than those of the pure breeding group.

For domestic and foreign markets, we have developed Tangyang chicken skewers, pickled plum chicken rolls, big-bone chicken dumplings, and new domestic market-style big-bone chicken barbecue products adapted to Japanese cuisine. After deep processing, it The added value has been greatly improved.
