[Abstract]
1. DL-beta-hydroxybutyrate (4 mM) increased the net rate of leucine transamination and the net rate of 2-oxoisocaproate (KIC) production in extensor digitorum communis muscles from fed chicks. 2. DL-beta-hydroxybutyrate at 1 and 4 mM inhibited leucine oxidative decarboxylation in muscles from fed chicks. 3. Acetoacetate at 1 and 4 mM inhibited leucine oxidative decarboxylation and total leucine oxidation, but increased net KIC production in muscles from fed chicks. 4. Both DL-beta-hydroxybutyrate and acetoacetate at 1 and 4 mM inhibited the net rate of leucine transamination and the rates of leucine oxidative decarboxylation and total leucine oxidation in muscles from 24-hr fasted chicks.
