Abstract
The ribeye areas (REA) of fattening culled dairy carcasses which measured using geometric method (GM) were significantly higher than those using plastic grid (PG) method with the averages of 84.12 and 81.42 sq.cm., respectively (p<0.01). The factor of ribeye sizes had highly significantly influenced on REA. The averages of REA for small, medium, and large sizes were 61.94, 80.85, and 105.51 sq.cm., respectively (p<0.01). In addition, the interaction between the fators of method and size affected on the REA. The averages REA of large size measured by GM method was 108.77 sq.cm higher than that measured by PG method 102.26 sq.cm. (p<0.05), whereas there was not significant difference for the small and medium sizes measured by both methods
