Abstract：In order to study the relationship between body weight and body measurements of 120-day-old Lion-hcad geese, a total of 501 (255 males and 246 females)geese were mcasured, and the correlation
and regression analysis were carried out. The results showed that the body weight and body measurements of male geese were significantly higher than those of female geese (P<0.01).There were significantly positive correlations bctween body weight and body measurements ( P<0.01).The regression model of predicting body weight by using body measurement traits for male Lion-head geese was Y=0.471X2+0.192X6+0.187X7+0.022X9+0.042X+0.055Xμ+0.475X-10.434，where Y was body weight, X2 was chest width, X6 was pelvic width, X7 was neck circumference,X9 was half-diving length,X10 was body slant length, X11 was keel length and X12 was tibia circumference. The regression model for female geese was Y=0.384X2+0.031X4+0.297X6+0.226X7+0.094X10+0.223X12-12.227，where Y was body weight, X2 was chest width, X4 was chest Angle, X6 was pelvic width, X7 was neckcircumference, X10 was body oblique length,and X12 was tibia circumference. Our results will provide important reference for the conscrvation and breeding of Lion-head geese.
