영어 초록

The objective of this research was to investigate the effect of dietary cottonseed meal (CSM) supplementation on carcass and meat quality characteristics of Hanwoo (Korean cattle) bulls. Twenty two months-old-Hanwoo bulls of eight heads (4 heads per treatments) were fed for 5 months on a diet with or without (control) CSM (500 g/head/day). The samples of M. longissimus dorsi from carcasses were used for the quality measurement. Dietary CSM supplementation did not affect the carcass traits of bulls and pH value, drip loss, water-holding capacity and fatty acid composition of beef loin. Crude protein and crude ash content of beef loin were significantly (p<0.05) higher in beef loin from bulls fed CSM than in the control. During storage of 5 days at 4℃, CIE a*, b*, C* and total color values were significantly (p<0.05) higher in beef loin from bulls fed CSM than in the control. Overall, the present results indicate that dietary CSM supplementation may improve the oxidation stability of Hanwoo beef loin.
