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 Zlotnicka Spotted breed and of crossbreed F1 (Polish Large White x Polish Landrace). The Zlotnicka Spotted pigs were slaughtered at about 106 kg of body weight and the cross-breed F1 pigs at about 114 kg. The carcasses of Zlotnicka Spotted pigs were fattier in comparison to the F1 cross-breeds. The intramuscular fat content was highly similar in the two groups (1,87 percent and 1,72 percent). The profile off fatty acids in meat was also similar in the groups being analyzed. Only the content of palmitic acid was significantly lower in the Zlotnicka Spotted pigs than in the F1 cross-breeds (28,16 percent versus 29,50 percent). A significant negative correlation was found between the mean backfat thickness and intramuscular fat content in the Zlotnicka Spotted pigs only
