The average value of SFA (43.37%) in SL pigs was higher than in WM and SBM pigs (Table 1).SL pigs showed higher PUFA content in MLLT than Mangalitsa pigs. These differences were mainly produced byhigher total n-6 PUFA content in MLLT of SL pigs (p < 0.001). However, SBM had a higher level of total n-3 PUFA(p < 0.001) than SL and WM pigs. These led to significantly lower n-6/n-3 ratios in MLLT of SBM pigs (p < 0.001).It is clear that the housing system and/or diet of Mangalitsa pigs can significantly affect this ratio. For example,Parunovićet al.3 found that the free-range Mangalitsa pigs showed a higher PUFA content in the MLLT than pigsreared indoors and fed conventionally. These differences were produced mainly by an almost four times higher totaln-3 PUFA content in the MLLT of the free-range pigs (p < 0.001), and also by slightly higher levels of total n-6
