In order to study the meat development value of princess chicken, the body size traits and slaughter performance of 12-week-old F^sub 1^ hybrid offspring of princess chicken ([male]) and kirin chicken([female]) were measured and the correlations between different traits were analyzed. The results showed that body length, keel length and shank length of male F^sub 1^ 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 F^sub 1^ 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 F^sub 1^ hybrid offspring.
