Abstract: In order to research the correlation between body size and body weight of Henan small tail han sheep and dedicate to new breeding selection work. This paper analyzed the correlation between body size and body weight of 98 Henan small tail han sheep with the SPSS software, based on Path Analysis and Correlation Analysis, and establish the most superior regression equation. The results showed that the body weight(〖AKY-〗) with the body height(X1), the body length(X2),the heart girth(X3),the chest width (X4), chest depth(X5), tail width(X6) and tail length(X7) were significantly positive correlations (P<0.01). The direct action and the indirect action of the body length, the heart girth, the chest width and chest depth were extremely maximum. The most superior regression equation was 〖AKY-〗=0.226X2+0.535X3+0.200X4.
