| Popis: | Preliminary observations have been made on the free amino acids in maternal and fetal plasma in prolonged gestation in the Guernsey cow, with the following findings: (1) Jugular venous plasma amino acid levels were the same in normal cows-and those with postterm dysmature calves. (2) Amino acid levels in umbilical vein plasma were higher than maternal in both normal and postterm fetuses: these differences were most marked in the normal calf plasma. (3) The low levels of some of the amino acids in the postterm fetal plasma suggest a degree of placental insufficiency during prolonged gestation and support previous evidence of impaired placental function. |
