This study was conducted to determine application possibility of mulberry (Morus alba) silage as a functional feed in feeding management of Korean native cattle for high quality beef production by analysing active components and antioxidative activity. The chemical analysis of mulberry silage indicates that the content of dry matter, crude protein, ether extract, crude fiber and crude ash was 28.41±3.12%, 12.43±0.28%, 2.47±0.18%, 20.29±0.75% and 6.98±0.12%, respectively. The content of 1-deoxynojirimycin (1-DNJ), which is representative active ingredient of mulberry and blood sugar descending component, was 0.568 mg/g and the content of γ-Aminobutyric acid (GABA), which is blood pressure descending component, was 5,936.22 pmol. Mulberry silage used in this study did not contain flavonoids but did contain total phenols for 21.69 ㎍/mg. 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity was increased with increasing the concentration of mulberry silage extracts and there was above 50% of scavenging activity at the concentration of 0.25 mg/㎖. Hydroxyl radical scavenging activity was also increased with increasing the concentration of silage extracts. Alkyl radical scavenging activity was high at the low concentration of silage extracts, which was above 50% of scavenging activity at the concentration of 0.125 mg/㎖. The result of this study indicated that there was high possibility of mulberry silage as a functional feed for beef cattle.
