[Postnatal development of the kidney concentrating ability, the renin-angiotensin system and the adrenal cortex hormones in the calf].
Post-natal development of plasma and urine osmolality, as well as plasma renin activity, aldosterone and cortisol levels were studied in calves between 1 and 9 months of age. The ratio of urine to plasma osmolality rose from 0.8 at an early post-natal age to 3.8 at the end of the study period. Plasma renin activity, plasma aldosterone and cortisol levels did not show any change during the post-natal development period. The plasma concentrations of these hormones were in the same range as is found in the adult.
