Abstract:

[Objective] To investigate the correlation of body weight, carcass weight, and body measurement of Wuliangshan sooty chicken of different genders. [Method] A total of 60 18-week-old Wuliangshan sooty chickens with half males and half females were chosen, and their body weight, carcass weight, body oblique length, keel length, tibia length, tibia circumference, hip width, chest width, and chest depth were measured. An independent sample t-test was used for statistical comparison. For correlation analysis, Pearson analysis was employed. [Result] The males had extremely significantly （P<0.01） higher body weight, carcass weight, body oblique length, keel length, tibia length, tibia circumference, hip width, chest width, and chest depth than those of the females. Extremely significantly （P<0.01） positive correlations between body weight and carcass weight, keel length, tibial circumference were found in the males. The females′ body weight had extremely significantly （P<0.01） and significantly （P<0.05） positive correlation with carcass weight and tibial circumference, respectively. [Conclusion] The male Wuliangshan sooty chicken had much higher body weight and measurement than the female ones. Body weight was positively correlated to carcass weight and tibial circumference. Selected body measurement associated with bone development, such as keel length, tibial length and tibial circumference, had certain correlation.
