Gross and HistopathologicalStudy of the Genitalia in Goats:1. Ovaries

Among the 340 samples collected from the pregnant and nonpregnant animals, 126(37.058%) were pregnant, 127(37.35%) were found without gross pathological abnormalities, and the remaining 43(21.64%) samples were found with gross and pathological abnormalities of ovaries. The present study is achieved to find out the gross and pathological lesions in ovaries of goats. The ovarian lesions were 72 (21.176%) abnormalities in 340 specimens recorded, the most common lesions were ovaro-bursal adhesion 28 cases (26; 7.647% mild and 2; 0.588% severe), para-ovarian cysts (22; 6.470%), follicular cystic ovary (7; 2.058%). Histopathologically, the follicular cysts characterized by the presence of a large empty cyst in the ovarian stroma surrounded by proliferating theca cells layer, and marked proliferation of granulosa cells layer. Cystic corpus luteum was (5; 1.470%), luteal cystic ovary (4; 1.175%). Microscopically, the cysts were lined by a fibrous layer surrounded by a luteinized theca cells layer. Other rare pathological conditions of the ovaries were an ovarian hematoma 4 (1.176%), ovarian tuberculosis, 1 (0.294%). Histopathologically, ovarian tuberculosis is characterized by typical granulomatous tubercle presence in the ovarian stroma characterized by pinkish caseous necrosis in the center surrounded with thick purple granuloma. Ovarian Cysticercus tenuicollis was 1(0.294%). It can be concluded that ovarian abnormalities constitute a percentage (21.176%), and ovarian tuberculosis was firstly recorded in Iraq and Kurdstan region.
