The purpose of this study is to compare and analyze the carcass traits of french giant meat quail and savimalt meat quail in order to provide reference for breeding and improvement of meat quail. The results show that french giant meat quail shows far higher body weight, carcass weight, carcass net weight, breast muscle weight (total), leg muscle weight (single) and leg muscles rate compared to savimalt meat quail (P<0.05). Moreover, heart weight, liver weight, slaughter rate, whole net carcass rate, heart rate and breast muscle rate of french giant meat quail are slightly higher than those of savimalt meat quail (P>0.05). For savimalt meat quail, carcass weight shows extremely significantly postive correlations with carcass net weight, heart weight, liver weight, breast muscle weight (total), leg muscle weight (single), slaughter rate and whole net carcass rate (P<0.01), the correlation coefficients are 0.988, 0.596, 0.557, 0.926, 0.899, 0.467 and 0.706, respectively. For the french giant quail, carcass weight shows extremely significantly postive correlations with carcass net weight, liver weight, breast muscle weight (total), leg muscle weight (single) and slaughter rate (P<0.01), the correlation coefficients are 0.949, 0.410, 0.863, 0.590 and 0.395, respectively.

Abstract
Materials and methods
60 samples of french giant meat quail and savimalt meat quail were collected, respectively. The culture room was provided with 24h lights and quail were allowed to drink water and eat freely throughout the expeirment. Fodders were supplemented artificially on the morning and evening every day. The culture temperature and humidity were determined according to culture management requirements.
At the end of culture experiment (5 weeks old), quail samples were killed by jugular vein bleeding, removed hairs and then dissected. Weights of all parts were measured by an electronic scale. The carcass traits measured included body weight, carcass weight, carcass net weight, heart weight, liver weight, breast muscle weight (total) and leg muscle weight (single).
Results and discussion
As can be seen from Figure 1, the results show that french giant meat quail shows far higher body weight, carcass weight, carcass net weight, breast muscle weight (total), leg muscle weight (single) and leg muscles rate compared to savimalt meat quail (P<0.05). Moreover, heart weight, liver weight, slaughter rate, whole net carcass rate, heart rate and breast muscle rate of french giant meat quail are slightly higher than those of savimalt meat quail (P>0.05). Bai et al. (2020b) showed that the body weight of 3-5 week old french giant meat quail was significantly higher than that of savimalt meat quail (P<0.05). The results of this study were similar to those of Bai et al. (2020b). Wei et al. (2011) demonstrated that body weight of Fengxian line of french giant meat quail reached 141.67g at the 4th week, while body weight of Wuxi line reached 177.63g. In the present study, body weight of French giant meat quail at the 5th week reached 146.13g, which is slightly lower than that reported by Wei et al. (2011).
* indicates significant difference (P < 0.05), while others indicate no significant difference (P > 0.05).
Body weight of savimalt meat quail has extremely significantly positive correlations with carcass weight, carcass net weight, heart weight, liver weight, breast muscle weight (total), leg muscle weight (single) and whole net carcass rate (P<0.01), the correlation coefficients are 0.998, 0.988, 0.600, 0.564, 0.926, 0.906 and 0.701, respectively (Supplementary Table I). Carcass weight also has extremely significantly positive correlations with carcass net weight, heart weight, liver weight, breast muscle weight (total), leg muscle weight (single), slaughter rate and whole net carcass rate (P<0.01), the correlation coefficients are 0.988, 0.596, 0.557, 0.926, 0.899, 0.467 and 0.706. Carcass net weight has extremely significantly positive correlations with heart weight, liver weight, breast muscle weight (total), leg muscle weight (single), slaughter rate and whole net carcass rate (P<0.01), the correlation coefficients are 0.609, 0.516, 0.954, 0.895, 0.436 and 0.798, respectively.
Body weight of french giant meat quail shows extremely significantly positive correlations with carcass weight, carcass net weight, liver weight, breast muscle weight (total) and leg muscle weight (single) (P<0.01), with correlation coefficients amounted to 0.996, 0.947, 0.395, 0.865 and 0.593. Besides, carcass weight shows extremely significantly positive correlations with carcass net weight, liver weight, breast muscle weight (total), leg muscle weight (single) and slaughter rate (P<0.01), with correlation coefficients amounted to 0.949, 0.410, 0.863, 0.590 and 0.395. Carcass net weight has extremely significantly positive correlations with breast muscle weight (total), leg muscle weight (single), slaughter rate and whole net carcass rate (P<0.01), with correlation coefficients amounted to 0.892, 0.578, 0.364 and 0.547.
