The aim of the present research was to determine the relationship between the live body weight, trunk length and pelt size in arctic foxes. The studies were conducted on 257 arctic foxes. Measurements of the body weight and trunk length were taken directly before slaughter. After slaughter, pelts were subjected to standard processing. Dried pelts were measured and the values obtained were compared with those concerning the body weight and trunk length of a given animal. Statistical differences between males and females were determined. The multiple regression method was employed to calculate the coefficients of correlation between the body weight, trunk length, and pelt length. Multiple regression formulas were derived to estimate the pelt size (trait Y) before slaughter based on the body weight (trait X1) and trunk length (trait X2). Those equations make it easier for breeders to determine the expected size of pelts in a given season before animals are slaughtered, and to estimate their market value.
