Table 3. Effects of dietary leucine supplementation on the hepatic metabolite concentrations 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; ATP, adenosine triphosphate; ADP, adenosine diphosphate; AMP, adenosine monophosphate; TAN, total adenine nucleotide, TAN = ATP + ADP + AMP; AEC, adenylate energy charges, AEC = (ATP + 0.5 ADP)/(ATP + ADP + AMP). Data are presented as means ± SEM (n = 8/group). Mean values within a row with unlike superscript letters were significantly different (P < 0.05).
