Meat Quality Traits of Longissimus Muscle of Hanwoo Steers as a Function of Interaction between Slaughter Endpoint and Chiller Ageing

Carcass characteristics and meat quality traits as a function of endpoint months of slaughter age (26vs 32mon) and chiller ageing (1vs 10d) were evaluated for m. longissmus of 26 Hanwoo steers fed with commercial diets including whole crop barley silage. Totally twenty six Hanwoo steers for 6mon of age that were fed until 26mon of age constituted the short termfed group and fed until 32mon of age constituted long-term fed group, Carcasses were chilled for 24 h and were graded, Strip loin samples were divided into two age groups (1 d and 10 d), Long-term feeding increased carcass weight, rib-eye area, yield grade, marbling score, firmness and quality grade of the meat. The feeding for 32mon produced tender, juicy meat (p
