| Abstract: | Effect of Different Feeding Restrictions on the Content of Intramuscular Fat as well as on the Fatty Acid Pattern of Total Lipids and Phospholipids in the Muscle of Heavy Pigs (> 160 kg LW) The intramuscular fat content, its fatty acid composition and the fatty acid pattern of the phospholipids were analyzed in meat samples of the musculus longissimus dorsi of heavy pigs (> 160 kg LW). The pigs were fattened at different energy levels: group I intensively (13 MJ ME/kg feed), group IV extensively (11.5 MJ ME/kg feed), group II and III at first extensively and at the beginning of the middle period (54 kg LW) and the final period (103 kg LW) resp. intensively. Less intramuscular fat contents were found in the animals of group IV. A few minor fatty acids in the intramuscular fat increased significantly in the extensively fed pigs; in addition, the contents of the saturated as well as of the monoen and polyen fatty acids were not influenced. The contents of monoen fatty acids and that of polyen fatty acids decreased significantly in the fatty acid pattern of the phospholipids. |
