The objective of this study was to determine effects of Arg supply on the expression of a se-lect set of genes related to AA metabolism, vascular function, cellular regulation of protein synthesis, and cell differentiation and turnover between the mammary and longissimus dorsi tissues. Six rumen-cannulated, lactating Holstein cows were used in a replicated 3 × 3 Latin square design with 14-d periods. Treatments were continuous abomasal infusion that supplied 0 (ARGx0), 49.2 (ARGx1), and 98.4 (ARGx2) g/d Arg in an otherwise complete AA mixture at 1054 g/d.
