Note that only significant associations are shown in this table. AFW = abdominal fat weight; CPCLM = crude protein content of leg muscle; SFT = subcutaneous fat thickness. Values within a row without a common superscript letter differ and values with superscript letters differ significantly (𝑃<.05and 𝑃<.01 each). Genotypes of a and b mean they differed significantly (𝑃<.05) and genotypes of a and B mean they differed great significantly (𝑃<.01).
