Abstract: Using goats sustained solely by abomasal feeding, the effect of increased protein intake on the concentrations of amino acids in the plasma of jugular blood was investigated. Casein was used as the sole source of dietary protein at levels of 0, 10, 15 and 20%. The concentrations of most of the free amino acids in the plasma were significantly lower when goats were given a casein-free diet than when they were fed casein-containing diets. The plasma glycine level was significantly higher when the goats were fed a casein-free diet than when fed casein-containing diets. The concentration of total amino acids in the plasma tended to increase in response to the dietary casein level although there was no significant effect. The total concentration of essential amino acids in the plasma was significantly higher in the 20% casein diet feeding than in the feeding of diets containing 10% and 15% casein and the ratio of essential to non-essential amino acid concentrations was significantly higher in the feeding of 20% casein diet than in the other feeding. Of the essential amino acids in blood plasma, the concentrations of branched-chain amino acids were significantly increased with an increase in dietary casein level. The proportions of branched-chain amino acids in essential amino acids were gradually increased with an increase of dietary casein level. The ratio of glycine to valine was altered markedly and the ratio of glycine to branched-chain amino acids was changed with an increase of dietary casein level. These ratios may be a useful index to nutritional evaluation of dietary protein.
