Over a period of five months in fall and winter, a total<br />number of 3046 uterine tracts were collected. Pregnancy was detected in 56.50% of ewes, 52.36% and 4.13% of which carried singleton and twins, respectively. The highest frequency of pregnancy was detected in<br />January (65.63%) and the lowest frequency was detected in March (35.02%). Among a total number of 1721<br />pregnant ewes, the most frequency of gestational age (34.68%) was recorded to be between 2 and 3 months of gestation, while 5.05% was detected to be above 121 days. Overall, the number of pregnant ewes with a gestational age over two months was considerable (59.83%). It was concluded that reproductive waste<br />resulting from slaughtering of pregnant animals is important in ewes in Khorram Abad and could be<br />prevented by an improved antemortem examination. https://ijvr.shirazu.ac.ir/article_2682_acaf12046e58dd56ac2d78233ae27585.pdf
