The objective of the present study was to determine the relationship between carcass fatness and intramuscular fat content, and the profile of fatty acids in pig meat of Złotnicka Spotted breed and of crossbreed F₁ (Polish Large White x Polish Landrace). The examined group comprised a total of 86 pigs, i.e. 60 Złotnicka Spotted pure breed pigs (Złp) and 26 F₁ cross-breeds (PLW x PL). The animals were reared under the ecological conditions. The Złotnicka Spotted pigs were slaughtered at about 106 kg of body weight and the cross-breed F₁ pigs at about 114 kg. The carcasses of Złotnicka Spotted pigs were fattier in comparison to the F₁ cross-breeds. The mean backfat thickness of 5 measurements was 29.62 mm (Złp) and 22.83 mm (F₁) respectively, and the differences were highly statistically significant at P≤0.01. The intramuscular fat content was highly similar in the two groups (1.87 % and 1.72 %). The profile of fatty acids in meat was also similar in the two groups being analyzed. Only the content of palmitic acid (C16:0) was significantly lower in the Złotnicka Spotted pigs than in the F₁ cross-breeds (28.16 % versus 29.50 %); (P≤0.05). A significant negative correlation was found between the mean backfat thickness and intramuscular fat content in the Złotnicka Spotted pigs only (r=-0.264*). Moreover, a significant positive relationship was proved to exist between the level of intramuscular fat and oleic acid contents C18:1 (r=0.612**), and a negative relationship relating to the linoleic acid content C18:2 (r=-0.732**). It is concluded that the negative relationship between the backfat thickness and intramuscular fat content is contingent on the pig breed type and that a higher intramuscular fat content is associated with the higher content of monounsaturated fatty acids (MUFA) in meat, represented, mainly, by the oleic acid C18:1.
