ABSTRACT

The study was conducted on 32 crossbred fatteners (Polish Landrace x Large White Polish) x (Duroc x Pietrain). Fatteners belonging to group S were fed the compound feed with a 6% supplement of soybean oil during the fattening period (30-100 kg) while fatteners assigned to group L were fed the same feed until they reached 70 kg of body weight. At this point, the soybean oil supplement was changed to a 6% supplement of lard. To evaluate fatty acid profiles in loin, 4 fatteners from each group were slaughtered after achieving 70, 80, 90 and 100 kg of body weight. In the loin of fatteners fed over the entire fattening period with soybean oil in the feed mixture, the content of SFA at 100 kg of body weight was significantly lower (pP<czegoś<?)
