Abstract

Sheep are significantly contributed to the meat production and milk yield in Duhok region. Dystocia is extremely common reproductive conditions affecting sheep and could causes death of both ewe and newborn. This research is aimed as a reconsidering study on the prevalence and etiology of birth difficulties in sheep. A total of 86 dystocia cases were recorded at the veterinarian clinic during the period from September, 2019 to February, 2020. The effects of factors analyzed by general linear models. The significantly highest prevalence was documented during winter season and ewes carrying male fetuses (p ≤ 0.05). Fetal dystocia 61(70.93%) cases outnumbered maternal causes 25 (29.07%) cases. The fetal malpresentation represent the most common fetal causes (43.02%), and ring womb (16.28%) as maternal causes. Other fetal causes included twinning, fetal oversize and monsters, whereas maternal causes include narrow pelvis, uterine inertia and toxemia. Fetuses were delivered by obstetrical management in 59 (68.60%) cases including manual traction in 55 (63.95%) cases, and hormonal treatment with manual traction in 4 (4.65%) cases. Whereas remaining cases 27 (31.4%) were surgically treated by caesarean section (CS). In conclusion, dystocia recorded as a major obstetrical problem in ewes and emergency assistance could reduce the mortality rate for both pregnant animals and their newborn. In order to safe high numbers of fetal and dam and to reduce the cost of treatments, sheep with dystocia should be considered as an emergency cases without postponing.
