| 1 | Correlation Analysis between Body Size and Slaughter Performance in F-_1 Hybrid Offspring of Princess Chicken and Kirin Chicken显示文摘In order to study the meat development value of princess chicken,the body size traits and slaughter performance of 12-week-old F1 hybrid offspring of princess chicken(♂) and kirin chicken(♀) were measured and the correlations between different traits were analyzed. The results showed that body length,keel length and shank length of male F1 hybrid offspring were significantly higher than those of female chickens(P < 0. 05). The live weight,carcass weight,semi-eviscerated weight,semi-eviscerated ratio,eviscerated weight,chest muscle weight,the leg muscle weight and heart weight of male chickens were extremely significantly higher than that of female chickens(P < 0. 01),and the leg muscle ratio and wings weight were significantly higher than that of female chickens(P < 0. 05),but sebum thickness of male chickens was extremely significantly lower than that of female chickens(P < 0. 01). Other indicators failed to reach the significant difference level. There were extremely significant or significant correlations between the slaughter performance and body size in F1 hybrid offspring. The regression equations between different indicators were identified and developed. The results provided a certain theoretical reference to predict slaughter performance indicators through a living body size measurement,and revealed an improved production performance of F1 hybrid offspring. | Li Naibin Du Bingwang Yang Fenxia Tao Lin Chen Jiebo | 2014 | Animal Husbandry and Feed Science2014，6，4： | 0 |
