[Gluconeogenetic capacity of suckling piglets and young pigs]

No marked gluconeogenetic performance was recordable from nursed piglets aged, between one and five days, in response to ACTH nor glucocorticosteroid application. Store pigs, aged twelve weeks, however, exhibited glucose rises of 34 per cent one hour after injection or 55 per cent three hours from ACTH application. The point was made, in an attempt to elucidate the above findings, that in newborn piglets, few days after birth, the gluconeogenetic capacity is insufficient because of functional immaturity of the liver. The behaviours of several metabolites in the liver and muscles of store pigs were examined under differentiated model conditions to check up and verify that view.
