The purpose of this study was to evaluate the effect of feeding dried grape marc to fattening steers on the fatty acids composition of the hepatic tissue (liver). The feeding trial used 20 steers with an average initial body weight of 253 kg assigned uniformly to two groups, control (C diet) and experimental (E diet). The E diet included 20% dried grape marc in the compound feed. The use of this winery by-product improved the feeding value of the liver for the human consumers. The concentration of polyunsaturated fatty acids increased, particularly the concentration of omega 3 and omega 6 fatty acids. Thus, compared to the control group, n-3 fatty acids increased by 18.10%, while n-6 fatty acids increased by 16.14%, in the experimental group.
