B. The intestinal branched-chain amino acid (BCAA) levels in the adult male and CtM Hanwoo (n = 10 in each group). BCAA levels in the luminal contents of the ileum, cecum, and colon were quantified by an enzymatic method using a BCAA assay kit. The lines, boxes, and whiskers in the box plot diagrams represent the median, first and third quartiles, and min-to-max distribution of replicate values, respectively. The scattered dots in the box plot diagrams represent the individual replicates.
