Correlation Analysis between Body Size Traits and Slaughter Performances on Xingyi Ducks

The research measured body size traits and slaughter performances and carried out the significance test and correlation analysis for 100 ten weeks old Xingyi ducks. The results indicated that the difference of body size traits was significant from different sex ducks (P<0.05), the slaughter performances had no significant difference except that the lean meat percentage of male were significantly lower than female and weight of leg bone and muscular stomach were significantly higher than female (P<0.05);The correlation analysis showed that all body size traits had a significant correlation, the majority of slaughter performances showed a significant correlation (P<0.05), and lung showed a little correlation with other traits in Xingyi ducks;The majority of body size traits showed significant correlation with slaughter performances (P<0.05);The weight of pectorales showed significant negative partial correlation with stank length and stank girth (P<0.05), the weight of muscular stomach showed significant positive partial correlation with length from beak to hip all, keel bone length and stank girth (P<0.05). These results will provide a fundamental statistics for study on Xingyi ducks in the future and as a insight for selection of Xingyi ducks.
