Carcass traits determining quality and yield grades
of Hanwoo steers.
were divided into three groups: grade A (lean; higher than 67.
Evaluation of traits in the USDA yield grade
equation for predicting beef carcass cutability in breed groups differing in growth and fattening characteristics.
The yield grade
results for four different ratios were 3.
The interaction of yield grade
with quality grade determines a two-dimensional scale on which to evaluate carcass value.
In carcass yield traits, most indicators including carcass weight, yield grade
, and back fat thickness except rib-eye area were not affected by dietary feeding system.
Backfat thickness was evaluated again at the end of the experimental period (77 days), classifying animals into two groups according to the yield grade
of 3-6 mm BFT (seven animals) and 6.
They have had to decide whether growth rate is more important than marbling or whether yield grade
is more important than weaning weight.
The beef grading system of Korea reveals two types of information: quality grade and yield grade
2]; Yield index; Yield grade
, converted to numeric value: grade A = 1, B = 2, and C = 3; Frequencies of carcass yield grade
, A:B:C, %) and quality traits (marbling score, 9 = the most abundant, 1 = devoid; meat color, 7 = dark red, 1 = bright; fat color, 7 = yellowish, 1 = white; texture, 3 = coarse, 1 = fine; maturity, 9 = mature, 1 = youthful; quality grade, converted to numeric value, grade [1.
After chilling the carcasses for 24 h at 4[degrees]C, cold carcass weight, indices (marbling degree, LM area, fat thickness, meat color, fat color, texture, and maturity at the 13 th rib) for yield grade
and quality grade of the carcasses were measured according to the Korean Beef Carcass Grading Standard (2014).
was classified with a scale of 1, 2, or 3, where 1 is high yield and 3 is low yield.
09) to increase the cold carcass weight by an average of 24 kg and did not affect yield traits such as dressing percentage, back fat thickness, longissimus muscle area, yield index, or yield grade
At this stage, carcass weight, longissimus muscle (LM) area, fat thickness, MS, yield index, yield grade
, meat color, fat color, texture, and maturity were examined and reported by an official meat grader.
However, no information is available on seasonal variations in beef cattle production traits, including quality grade (QG) and yield grade
(YG), in Korea.
