The research method used is survey method by measuring and weighing directly and the data obtained is tabulated with mean value, standard deviation and coefficient of variation, then analyzed using spss. There was no statistically significant correlation (P> 0,05) between body length and body weight with equation Y = 434,526 + 0,752X with r = 0,074% and R2 subangsi = 0,5%. There were statistically significant correlation (P <0,05) between chest circumference and body weight with the equation Y = 560,388 + 5,187X with closeness r = 70,5% and R2 subangsi equal to 49,6%. There was no statistically significant correlation (P> 0,05) between body length and carcass weight with equation Y = 276,585 + 0,060X with r = 0,19% and R2 subangsi by 0.000%. There were statistically significant correlation (P <0,05) between chest circumference and carcass weight with the equation Y = -195,678 + 2,239X with r = 0,967% and R2 subangsi of 0,556%.
