The concentrations of 23 amino acids in the plasma of 13 healthy foals were determined before suckling, when foals were 1 to 2 days old, 5 to 7 days old, 12 to 14 days old, and 26 to 28 days old. The ratio of the branched chain amino acids to the aromatic amino acids was also calculated at the 5 time points. Analysis of the concentrations at the 5 ages revealed a significant temporal relationship for each amino acid ranging from a polynomial order of 1 to 4 inclusively. There were significant differences between several concentrations of amino acids in plasma at specific sample times; however, no consistent patterns were revealed. The concentrations of amino acids in healthy foals were markedly different from previously determined values in adult horses. The significant differences in the concentrations of amino acids in plasma of healthy foals at the 5 ages may represent developmental aspects of amino acid metabolism or nutrition.
测定了13匹健康马驹在出生后1至2日龄、5至7日龄、12至14日龄以及26至28日龄时,哺乳前血浆中23种氨基酸的浓度。同时,还计算了这5个时间点支链氨基酸与芳香族氨基酸的比例。对这5个年龄段的氨基酸浓度分析表明,每种氨基酸都存在显著的时间关系,多项式阶数范围为1至4。在特定采样时间,血浆中几种氨基酸的浓度存在显著差异;然而,未发现一致的模式。健康马驹血浆中氨基酸的浓度与先前测定的成年马的值显著不同。健康马驹在这5个年龄段血浆中氨基酸浓度的显著差异可能代表了氨基酸代谢或营养的发育方面。
