FIGURE 2.

Plasma concentrations of amino acids (A–E) and total dispensable amino acids (F) from Holstein cows individually fed a control diet or the control plus rumen-protected Met (0.9 g/kg dry matter intake) during the last 28 d before parturition. Data reported had a significant treatment × time (Treat × Time P < 0.050) effect or tended (Pro, P = 0.064) to have a significant interaction effect. Values are means ± pooled SEMs, n = 10 per treatment group. *Means differ (Treat × Time P < 0.050).
