Abstract:

Ten body type traits of Jin-Ding Duck were studied. The Mean and variability of indicators of these traits and the coefficients of correlation among them were computed, the indexes which provided the scientific basis for breeding and improved the native breeds. The result indicated that ten body type traits were divided into three components (85.441% cumulative for the male, and the representative traits were weight, Chest depth, pelvis width, Tibia Wai and Neck length. Eleven body type traits were divided into four components (85.244% cumulative) for the female, and the representative traits were weight, pelvis width, chest width, Chest depth, Sunenaga and Neck length.
