Abstract:
The F1 generation of Xichuan Black-bone♂×Yellow Shank Silky chicken ♀,Xichuan Blackbone ♂ ×Black Shank Recessive White ♀ and Xichuan Black-bone×Xichuan Black-bone were employed as materials in this research. The growth traits of body weight,body slanting length,breast bone length,shank girth, shank length,chest width,chest depth,and the carcass and meat quality traits of semi-evisceration weight, evisceration weight,abdominal fat weight,breast muscle weight,leg muscle weight,fat bandwidth,skin fat thickness,breast muscle shear force,leg muscle shear force,muscle water loss rate,pH,were determined and analyzed by the common method. The results showed that the growth traits,slaughter performance and carcass quality of the hybrid group were better than those of the pure breeding group in the F1 generation. Xichuan Black-bone♂× Yellow Shank Silky chicken ♀ was optimal on the growth traits and slaughter performance,meat quality,especially muscle fiber traits and apparent traits of while Xichuan Black-bone ♂ ×Black Shank Recessive White ♀ was the better than those of Xichuan Black-bone ♂ ×Yellow Shank Silky chicken ♀ . The performance of Xichuan Blackbone has been promoted by hybrid,showed excellent heterosis.
