Table 4. Effects of dietary leucine supplementation on the activities of hepatic mitochondrial enzymes related to energy metabolism in normal birth weight and intrauterine growth-retarded weanling piglets.

¹⁾ NBW-CON, normal birth weight group given a control diet; NBW-LEU, normal birth weight group given a leucine-supplemented diet; IUGR-CON, intrauterine growth-retarded group given a control diet; IUGR-LEU, intrauterine growth-retarded group given a leucine-supplemented diet; BW, birth weight; PDH, pyruvate dehydrogenase; CS, citrate synthase; ICDH, isocitrate dehydrogenase; α-KGDH, α-ketoglutarate dehydrogenase; MDH, malate dehydrogenase. Data are presented as means ± SEM (n = 8/group). Mean values within a row with unlike superscript letters were significantly different (P < 0.05).
