These samples were collected from the slaughter house of Duhok area. Physiological activities of these samples were determined during 3 seasons of a year. These were 91 samples (39.57%) from non pregnant goat and 139 samples (60.43%) from pregnant goats. The sexual activities of the three samples were measured then weight of ovaries and corpus lumen found in the ovaries during the three reasons.

The size of corpora letea in right ovary was bigger in size and weight than that in the left ovary . The percent of single embryo was 65.09 most of them in the right horn (84.55%) , while the percent of twin was 33.14% some of them in the right horn (37.5) and (62.5%) in the left side and one case of triple (1.77%).
