Abstract

This study investigated the influence of Swedish outdoor feeding systems on the fatty acid composition and tocopherol content of M. Longissimus dorsi from beef. Dietary effects of pasture (PA), silage, and silage supplemented with grain (SIG) were compared. Each dietary group consisted of six animals. Higher levels (P < 0.05) of polyunsaturated fatty acids (PUFA) were found in the PA treatment. The n - 6/n - 3 fatty acid ratio of total lipids in the muscle tissue was in the range 1.2-1.5. The SIG treatment increased the n - 6/n - 3 ratio and decreased the total PUFA content of muscle tissue. The lipid class composition and the content of alpha-tocopherol in the meat showed no differences among treatments. (C) 2007 Elsevier Ltd. All rights reserved.
