Swenson, J.E., Sandegren, F., Söderberg, A. & Franzén, R. 1995: Estimating the total weight of Scandinavian brown bears Ursus arctos from field-dressed and slaughter weights. - Wildl. Biol. 1: 177-179.
Regressions are presented to predict the total weight (TW) in kg of Scandinavian brown bears Ursus arctos from field-dressed weights (FW), where TW = 4.01 + 1.16 × FW, and slaughter weights (SW), where TW = 4.63 + 1.49 × SW. Both regressions had high predictive values (r² = 0.97) and were not significantly affected by sex or genetic lineage of the bears. Formulas to calculate confidence intervals are also presented.
