The meat from hunted wild boar juveniles (N = 18) and yearlings (N = 17) was analysed to assess the influence of age and the ultimate pH value on selected quality traits. The analysed meat of 55.56% of the juveniles and 64.71% of the yearlings was characterised with normal pH. The pH had been measured 24 and 48 h post mortem. More cases of high ultimate pH (pHu > 5.8) and high maximal pH (about 6.2) have been noted in the meat of younger animals compared with older ones. We found no effect of pHu on the colour coordinates of analysed wild boar meat. A slight effect of age was observed for the lightness (L*) coordinate. The postmortem time was the most important factor influencing meat colour [L*, yellowness (b*), and hue angle]. A high pHu was related to lower drip loss (P = 0.001), lower percentage of free water (P = 0.036), lower cooking loss (P = 0.001), and lower plasticity (P = 0.042). The meat from juveniles showed higher plasticity than meat from yearlings. Summing up, both the pHu level and the age of wild boars may affect some qualitative patterns of meat, changing the technological usability of this raw animal product.
