Abstract:
The objective of this study was to compare fatty acid profiles of Kabinburi cattle and native cattle. Twenty male Kabinburi (KB) cattle and eighteen male Native cattle (N) at age of one year old were raised using Ruzi grass (8.27% CP) to final liveweight of 600 kg. and 250 kg., respectively. They were slaughtered at 2-2.5 and 1.5-2.5 years old (KB vs N) approximately. Fatty acid profiles of saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), polyunsaturated fatty acids (PUFA), ratio of polyunsaturated fatty acid to saturated fatty acids (PUFA/SFA), omega-3, omega-6, and a ratio of omega-6 to omega-3 were measured in KB and N taken from loin eye at the 7-8th rib using gas chromatography. The results showed that KB fatty acids profiles (SFA, MUFA, PUFA, PUFA/SFA, and omega-6) were not statistically different from those of N. Palmitic acid and stearic acid were major SFA found in KB (34.02% palmitic acid and 8.87% stearic acid) and N (32.22% palmitic acid and 4.33% stearic acid). Oleic acid and palmitoleic acid were the major composition of MUFA in KB (17.69% oleic acid and 1.75% palmitoleic acid) and N (7.81% oleic acid and 2.42% palmitoleic acid). Docosahexanoic acid or DHA and linoleic acid were PUFA constituted in the KB (2.17% DHA, and 3.10% linoleic acid) and N (4.63% DHA, 2.32% linoleic acid). Omega-3 in N (6.49%) were significantly higher than KB (3.04%), as a result of this, ratio of omega-6 to omega-3 of N (1.41%) were lower than KB (3.59%) (P<.05).
