Abstract
The purpose of this study was to determine the effects of different crude protein levels in the concentrates on carcass and meat quality of Hanwoo steers. A total of thirty 5.3-month-old castrated Hanwoo calves ($135.6{\pm}10.52$ kg) were randomly allocated into either control or treatment group. The animals were separately housed to 5 heads per group. Crude protein levels in concentrates for growing, fattening, and finishing phases were 14, 13, and 11% for control group and 16, 15, and 14% for treatment group respectively. Comparative analysis of carcass characteristics, physico-chemical characteristics, and fatty acid composition in M. longissimus dorsi of Hanwoo steers were carried out. There was no statistical difference in average cold carcass weight between control (411.9 kg) and treatment (419.9 kg) group. Also, dietary crude protein level in concentrates did not affect M. longissimus dorsi area, backfat thickness, and meat yield index. In contrast, the marbling score in treatment group was higher (p<0.05) than the control group. Also, treatment group showed significantly higher (p<0.05) values than control group for CIE L-value, Mono-unsaturated fatty acids and oleic acid composition. Therefore increasing crude protein levels of concentrates in Hanwoo steers during growing and fattening phases might be beneficial for the improvement of meat quality.
