Growth hormone, insulin and glucose concentrations in bovine fetal and maternal plasmas at several stages of gestation.


For cows on d 137 (n = 6), 180 (n = 8), 226 (n = 9) and 250 (n = 5) of gestation (Exp. 1), concentrations of insulin and glucose were two- to three-fold less (P less than .01) in fetal venous plasma than in uterine arterial plasma. Concentrations of growth hormone, conversely, were 10- to 20-fold greater (P less than .01) in fetal venous than in uterine… (More)
