Abstract

The morphological development of uterus in 60-, 90-, 120-day-old fetuses at gestation and neonates of Korean native goats were investigated by light microscopy. 1. In the 60-day-old fetuses, uterine walls differentiated and divided into the endometrium, myometrium and perimetrium. 2. In the 90-day-old fetuses, the blood vessels appeared in the uterine walls, in the 120-day-old fetuses the nodules (primordial caruncles) appeared first in the endometrium. 3. In the 120-day-old fetuses, the gland primordia observed on the uterine epithelium. In the neonates, the developing uterine glands were more number and deeper than those of 120-old fetuses. 4. PAS reaction of the mucosa cells in the endometrium was reacted weak, moderate and strong at 90-, 120-day-old fetuses and neonates, respectively.
