Abstract
This study was carried out to elucidate the effect of different rearing system on cortisol level, stress hormone, and fatty acid composition in the edible muscle tissues. These steers were reared in two different systems including antibiotic-free (ARS) and conservative system (CRS). In the M-Longissimus tissue, cortisol level was significantly lower in ARS than CRS, (p=0.0176). But, the levels of total saturated and unsaturated-fatty acids does not differ in ARS as CRS (p >0.05). However, the total saturated fatty acid levels tended to be greater in CRS and the total unsaturated fatty acid levels tended to be greater in ARS. However, the level of n-6 unsaturated fatty acid was higher in ARS than CRS (p=0.004). Especially, levels of linoleic acid (LA) and ${\gamma}$-linolenic acid (GLA) were significantly higher in ARS (p <0.01). Cortisol level and the n-6 fatty acid content in muscle tissue were negatively correlated (at p=0.00140.) In conclusion, ARS may produce beef with higher quality which contains lower cortisol and greater n-6 fatty acids, such as ALA and GLA.
