ABSTRACT
At the 20th week, body weight, carcass weight, liver weight and dressing percentage of Korean quail are significantly higher than those of the rest two quail species (P<0.05). The whole net carcass weight and whole net carcass rate of China yellow quail are far higher compared to those of Beijing white quail (P<0.05). Rate of chest muscles and rate of leg muscles of Beijing white quail are significantly higher compared to those of Korean quail and China yellow quail (P<0.05). At the 38th week, Korean quail and China yellow quail show significantly higher body weight, carcass weight, whole net carcass weight, breast muscle weight, liver weight and rate of liver than Beijing white quail (P<0.05). Moroever, Korean quail has significantly higher dressing percentage than Beijing white quail (P<0.05). The whole net carcass rate of Beijing white quail is greatly higher compared to those of Korean quail and China yellow quail (P<0.05). Carcass weight of China yellow quail presents extremely significant positive correlations with body weight, whole net carcass weight, heart weight, liver weight, breast muscle weight, leg muscle weight and dressing percentage (P<0.01). The correlation coefficients are 0.997, 0.807, 0.378, 0.645, 0.695, 0.352 and 0.362, respectively. Carcass weight of Beijing white quail presents extremely significant positive correlations with body weight, whole net carcass weight, liver weight, breast muscle weight, leg muscle weight and dressing percentage (P<0.01), with correlation coeffiecients of 0.997, 0.799, 0.419, 0.719, 0.554 and 0.498, respectively. Carcass weight of Korean quail also show extremely significant positive correlations with body weight, whole net carcass weight, heart weight, breast muscle weight and leg muscle weight (P<0.01), showing correlation coefficients of 0.997, 0.790, 0.392, 0.641 and 0.406, respectively.
