In this paper 14 parameters of wild boar tusks were analyzed. The analyzed sample contained 26 pairs of lower and upper canines (52 lower and 52 upper canines in total), originating from state hunting grounds No. VII/4 “Garjevica” and VII/15 “Zapadna Garjevica”. Measured parameters showed statistically high positive and significant relations with age according to Brandt and Bieger methods of estimation, but lower and even negative, non-significant relations with age assessed by tendon method. Obtained re­sults indicate necessity of re-evaluation of tendon method of age estimation (validation for specific wild boar population), or even to drop this method from further use. The parameters used to estimate age by Bieger and Brandt methods showed higher correlation to age in more curved tusks. By increasing age a relatively continuous growth of other parameters was observed. Within that, correlation of average length of lower canine with age is much higher than the correlation of canine width and age (R2=0.799; p<0.0001; respecti­vely R2=0.62; p<0.0001). Highest increase, expressed in trophy value (CIC points) is in average width of lower canine, while lowest increase shows upper canine girth. The lower canine width (r=0.98; p<0.01) and length (r=0.98; p<0.01) showed highest correlation with trophy value. Upper canine girth and total tusk curves (of both upper and lower canines) expressed relatively high, but still much lower correlation (r=0.87; p<0.01; respectively r=0.77; p<0.01). In general, relatively high and statistically significant correlation between all trophy evaluation parameters were found (p<0.01), ranging from r=0.62 (between girth and tusk curves) to r=0.98 (between lower canine length and width).
