Altered Concentrations of Aldosterone in Neonatal Calves During Chronic Hypoxia and the Subsequent Recovery Period

Significant changes occur in both blood composition and plasma volume of the calf within the first few hour after parturition (McEwan et al., 1968). These changes require sensitive and reliable regulatory mechanisms to maintain electrolyte balance and prevent fluid dyshomeostasis. Although the time required for maturation of the renal system in calves is much shorter than in most experimental animals (Dalton, 1968), significant electrolyte imbalances are a common clinical finding in neonatal calves.
