抄録

Levels of free amino acids were examined in plasma of carp at 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, and 24 hours after being fed casein-gelatin (control), gelatin (diet 2), and gelatin diet with essential amino acids uncoated (diet 3) or coated with casein (diet 4). Also, the balance of essential amino acid in plasma (BEAAp) was calculated in a manner similar to that for the determination of EAA index, using those of the control group as references. Almost all EAA in fish fed diets 3 and 4 reached maximal levels and dropped to fasting lvevls faster than in fish fed the control diet. In fish fed diet 4, levels of tryptophan were higher, but those of leucine were lower throughout the 1-8 hour period, than in fish fed diet 3; levels of all EAA (except lysine and arginine) from fish fed diet 2 remained low, with vague peaks at 4 hours. Values for BEAAp in all treatments droppid to the lowest values at 6 hours after feeding. Those for diets2, 3, and 4 were 32.3, 57.9, and 86.7% respectively and those from diet 4 were always higher than those from diet 3. Highly significant correlations between the BEAAp value at 6 hours and the average weight gain, feed effciency, or protein efficiency ratio were confirmed. These results indicated that coating amino acids with casein improved plasma amino acid balance, probably by altering the absorption and retention times of tryptophan and leucine.
