T3 is the height at the highest point of cranial part.
T2 is the height at the mid of breast length.
T1 is the height measured from 1 cm far a way of the end of caudal part.
Width is the distance of widest area in the middle of breast.
Length represents the longest distance of the breast.
Means within a row followed by different superscript letters differ significantly (p<0.05).
WS, white striping; WB, wooden breast.
