ABSTRACT
The purpose of this study was to investigate the early growth performance of French giant quails and Savimito quails.In this study, body weight, tibia length, chest depth, chest width, sternum length, body length and tibia circumference of 3-5 weeks old meat quails were measured.The results showed that the at 3-5 weeks of age, the body weight, chest depth, body length, shank length, and sternum length of the French giant female quail were significantly higher than those of the Savimite female quail (P<0.05), while only the body weight of the French giant male quail was significantly higher than that of the Savimite male quail (P<0.05). At 5 weeks old, the shank circumference of the French giant female quail was significantly lower than that of the the Savimite female quail (P<0.05).The regression equation of body weight to body size of Savimai quail was Y=-64.849+16.153X1+27.5X2+11.6 X3, with a fitting degree of 0.865. The regression equation of body weight to body size of French giant quail was Y= -148.103+11.851X1+20.927X2+59.278X4, with a fitting degree of 0.883. X1, X2, X3 and X4 in both regression equations represented body length, sternum length, chest depth and tibia circumference, respectively.
