[Insulin and cortisol levels in blood plasma and adrenal gland mass in swine during the perinatal period].
The level of immunoreactive insulin activity and glucose in blood plasma of the umbilical vein was found to be lower than that in maternal venous blood plasma, in the last third of intra-uterine development, that is between the 80th and 112th day. No age-dependent differences were recordable regarding immunoreactive insulin activity in foetal blood plasma. Concentrations of glucose and immunoreactive insulin in venous blood plasma of piglets were found to rise, within 24 hours from birth, due to milk intake. Such rises were statistically significant but differed by individuals. None of the above parameters increased in fasting piglets. Cortisol in foetal blood plasma was found to be low, usually less than 5 ng/ml, on the 80th, 100th, and 106th day of intra-uterine life, but it went up between the 106th and 112th day. The highest concentrations were recorded from the oldest foetuses, 114 day of intra-uterine development. The cortisol levels in the blood plasma of the mothers of the above mentioned foetuses varied between 5 ng/ml and 70 ng/ml. Relative adrenal gland weight in animals aged 112 and 114 days was found to be significantly higher than that in foetuses aged 80, 100, and 106 days. No significant postnatal change in relative adrenal gland weight was recorded from piglets in the first nine days of life.
