Cardiovascular and hypothalamic-pituitary-adrenal axis development in late gestation fetal sheep and young lambs following modest maternal nutrient restriction in early gestation.

The effect of a 15% reduction in maternal nutrition for the first 70 days of gestation on cardiovascular and hypothalamic-pituitary-adrenal (HPA) axis responses to administration of corticotropin releasing hormone (CRH) + arginine vasopressin (AVP) was studied at 128 +/- 0.7 days gestation in fetal sheep and postnatally, at 85 +/- 4.5 days in young lambs.
