The content of amino acids (%) in this study is expressed as the percentage of amino acids per unit mass of the sample.
EAA=Threonine+Valine+Methionine+Isoleucine+Leucine+Phenylalanine+Histidine+Lysine+Arginine.
NEAA=TAA–EAA.
Means within a row with different subscripts differ when p-value<0.05.
LD, longissimus dorsi; PM, psoas major; BF, biceps femoris; EAA, essential amino acids; NEAA, nonessential amino acids; TAA, total amino acids.
