Correlation Analysis on Carcass Performances and Body Weights of Korean Quails

In this study,300 Korean quails(half of male and female) were raised from 7 days to 38 days under the same feeding condition.During the experiment,the body weights of the quails were measured once a week from 10 days old.At the end of raising experiment,150 quails(half of male and female) were randomly selected for slaughtering,and the body weights and carcass performances were analyzed.The results showed that the body weights of female quails were very significantly higher than those of males(P0.01),except the body weight at 10 days;the slaughter weight,bloodletting weight,carcass weight,half eviscerated weight,eviscerated weight,percentage of half eviscerated yield,weight of chest muscle and weight of thigh muscle of females were significantly higher than those of males(P0.05 or P0.01).The results of correlation analysis indicated that there were very significantly positive correlations among the body weights at different ages(P0.01);and the positive correlations were showed among the different aged body weights and carcass traits(P0.05 or P0.01),except percentage of half eviscerated yield,percentage of eviscerated yield,weight of chest muscle,weight of thigh muscle in females and dressing percentage,percentage of half eviscerated yield,weight of chest muscle,weight of thigh muscle in males.
