¹ Namık Kemal Üniversitesi, Ziraat Fakültesi, Zootekni Bölümü -Tekirdağ - The objective of this research was to investigate the relationship between live weight and body measurements. Total 109 Japanese quail were used in the study and their aged 72 day. The some body measurements (mm) (wing length, body length, leg length, beak length, beak width and chest girth measurements) and live weight (g) were taken from every animal. The relationships between live weight and body measurement effected on growth performance of animal were examined with correlation coefficients and Principal Component Analysis (PCA). Live weight and body length were found as statistically significant for female and male animal groups with ANOVA (p <0.05).The highest correlation coefficients were calculated between live weight and body length (r = 0.47 ) and beak length with beak width (r = 0.47). Principal component analysis summarized 8 variables with 2 principal component and It was found that for all traits first 2 principal components explained 79 % of total variation. As a result, live weight, wing length, body length and chest girth were found high correlated but foot and beak measurements are low correlated on growth perfomance.
