Abstract
The nutritional quality of M. Longissimus dorsi in the autochthonous Krškopolje pig breed and commercial fatteners from intensive Slovenian farms was compared. Commercial fatteners were divided into two groups according to lean meat percentage: MEATY and FATTY groups. The Krškopolje pigs (KK group) and the FATTY group had higher intramuscular fat content than the MEATY group. The lowest saturated fatty acids (SFA) proportion was found in the KK group and the highest in the FATTY group. The KK and FATTY groups contained higher proportions of monounsaturated fatty acids (MUFA) as well as lower proportions of polyunsaturated fatty acids (PUFA) compared to the MEATY group. The highest n-6 PUFA proportion was found in the MEATY group. The n-3 PUFA proportion differed between the MEATY and FATTY groups. The FATTY group had the lowest ratio of polyunsaturated to saturated fatty acids as well as the highest atherogenic index.
