| Ham bone-out | 17.04 ± 0.790a | 16.98 ± 1.189b | 16.71 ± 1.667c | 0.000 |
Each value is presented as mean ± SD.
Population numbers for Grades 1+, 1, and 2 are 145,872, 157,833, and 115,616, respectively.
p-value is obtained by t-test of heteroscedasticity variance.
Different superscripts in the same row differ significantly in the analysis of heteroscedasticity variance.
