Abstract
The present study was designed to describe the histological changes in the uterine horn of pregnant and non- pregnant adult Iraqi ewes. uterine horn samples of Twenty slaughtered ewes were collected from Kerbala abattoir and divided into four groups, group 1 represented non pregnant ewes, group 2 represented pregnant ewes in the early stage of gestation period (20 – 30) days, group 3 represented pregnant ewes in the middle stage of gestation period (60 – 90) days, group 4 represented pregnant ewes in the late stage of gestation period (100 – 130) days, age of the fetus was determined by measuring crown-rump length. The samples were fixed in 10 % formalin, routine histological technique was done and stained with hematoxylin and eosin. Thickness of endometrium of the uterine horn was increased significantly (p ≤ 0.05) in pregnant ewes especially in the middle stage of pregnancy, myometrium significantly decreased ( p ≥ 0.05) in the late stage of pregnancy while there were no significant differences in the perimetrium between pregnant and non- pregnant ewes. The number and the diameter of endometrial glands also showed a significant increase (p ≤ 0.05) in pregnant ewes rather that in non-pregnant one and height of luminal epithe-lium was significantly decreased ( p ≥ 0.05) with the pregnancy advanced, also the glandular epithelium significantly decreased ( p ≥ 0.05) in the middle stage of pregnancy.
