In the paper, basic quality parameters of pig adipose tissue of carcasses of fatteners were analysed and assessed. The fatteners were born using two different variants of cross-breeding: cross-breeds pbz x (pi x du) (group 1) and hybrid cross-breeds from the Hypor x PIC 337 line (group 2). The comparison of subcutaneous and leaf fats shows that leaf fat contains less water and protein and more fat compared to back fat. In fat materials from cross-breeds from the hybrid line (group 2), a lower protein level was determined and this fact can favour storage stability of those materials. The colour values measured show they yellowness to have the decisive impact on how this characteristic develops, it was found that the back-fat from group 1 was lighter than from group 2
