Abstract	Holstein bull calves maintaining reflex closure of the esophageal groove after early -weaning were used to examine the effect of abomasal administration of 0.288g/kg BW/d of Lglutamine (Gln) on nitrogen (N) balance and plasma amino acid concentrations. In Experiment 1, comparisons with the administration of iso-nitrogenous diammonium citrate (DAC) were made from 9wk of age using 10 calves in a reversal method with five replicates and 2wk-period. In Experiment 2, comparisons with that of DAC or iso-nitrogenous mixture of 0.111g/kg BW/d of DL-methionine (Met) and 0.333g/kg BW/d of L-lysine monohydrochloride (LysHCl) were made from 14wk of age using 6 calves in a 3×3 Latin square design with two replicates and 2wk period. Basal ration based on corn, soybean meal and rice straw was fed at 27g/kg BW/d in Experiment 1, and at 20g/kg BW/d in Experiment 2. In both experiments, administration of LGln increased plasma Gln concentration only in the absorptive state, but N balance was not affected by abomasal N supplements. Plasma concentrations of branched-chain amino acids did not differ between the supplements of L-Gln and DAC except for leucine, but were decreased by administration of DL-Met and L-LysHCl in Experiment 2.
