摘要：

Subjects were Polish Landrace (PL), Polish Large White (PLW), Pulawska, Hampshire, Duroc, Pietrain and line 990 gilts tested in the Polish Pig Performance Testing Stations (SKURTCh). A total of 4430 animals were investigated. During the test, animals were kept individually and fed ad libitum. Intramuscular fat (IMF) content was determined as crude fat by Soxhlet extraction with fat solvents (Soxtherm SOX 406, Gerhardt). Samples for analysis were taken from the middle cross-sectional area of m. longissimus dorsi behind the last rib. The highest level of IMF was observed for Duroc animals (2.23%) and the lowest for the Pietrain breed (1.66%). In the two most popular breeds in Poland (PLW and PL), this parameter was below the level acceptable for good quality meat (1.84% and 1.76%, respectively). IMF content of in. longissimus dorsi showed high variation ranging from V = 27.8% to V = 41.8% according to the breed.
