Effect of a low-protein diet supplemented with rumen-protected methionine and lysine on the expression of genes involved in fat metabolism in the liver (A, B, C) and muscle (D, E, F). Data are expressed as means ± SEM indicated by vertical bars. Different letters indicate a significant difference among the three dietary treatments (P < 0.05). NP, adequate protein diet (n = 7); LP, low-protein diet (n = 6); LP + RML, low-protein diet supplemented with rumen-protected methionine and lysine (n = 7)
