[The development of the adrenal cortex in pig (Sus scrofa domestica). (A contribution on the development of the fetal interior zone of the adrenal cortex in pig) (author's transl)].

The adrenals of pigs have been investigated histologically and histochemically during different periods of time pre- and postnatally. The pig (Sus scrofa domestica) shows a proper fetal cortex in the prenatal development of the adrenal gland. This involves slowly during the last quarter of pregnancy. A weight reduction is not noted thereby. Just before delivery the adrenal cortex of the pig has been subdivided into a zona arcuata and zona fasciculata. The zona reticularis develops only postnatally.
