Abstract: The objective of this study was to compare the fatty acid composition of the Longissimus dorsi muscle of Charolais crossbreds (75%; with 25% Thai native cattle blood) and Thai indigenous Upland cattle (n=8 each). The animals were fed ad libitum grass and supplemented with concentrate at 1.5%/day of body weight. The cattle were on average four years old at slaughter. As a result, the crossbred beef had higher proportions of C16:0 and C18:0 of total lipids than the Upland cattle (P<0.05). At the same time, C14:1 and C18:2 cis-9, trans-11 (conjugated linoleic acid) was lower than in Upland cattle (P<0.05). Overall, this meant higher saturated fatty acid proportions in the crossbreds compared with the Upland cattle, while the opposite was true for the sums of monounsaturated fatty acids and polyunsaturated fatty acids, and the ratio of polyunsaturated to saturated fatty acids (P<0.05). This meant that the beef from the Upland cattle was better nutritionally for humans than the crossbreds.
