Abstract: In order to study the relationship between body measurement traits and slaughter performances of Xuhai Henn Spur Chicken, 24 Xuhai Henn Spur Chicken (12 male, 12 female) of 13 weeks were chosen randomly. Body measurement traits and slaughter performances were measured and analyzed using bivarite correlation analyze and canonical correlation analyze. The results showed that shank girth, shank length and body slanting length had highly significant or significant correlation with most traits. There were highly significant or significant correlation between slaughter performances except muscular stomach weight. The results of canonical correlation analysis showed that the first canonical correlation coefficient between body measurement traits and slaughter performances was 0.967 which explained 72.6 percent of total correlation and was highly significant. The analysis incicated that main traits for the canonical correlation coefficients were shank length, chest width, half-eviscerated weight, carcass weight. The results of the study offered some references for early breeding of Xuhai Henn Spur Chicken.
