Laparohysterotomy is frequently performed for managing dystocia in small ruminants for various indications. Various etiological factors recorded in present study included insufficient dilatation of cervix (54.15%), postural abnormalities of limbs (13.89%), foetal emphysema (8.33%), fetal oversize (5.56%), uterine torsion (5.56%), postural abnormalities of head (4.17%), rupture of uterus (2.77%), foetal monsters (2.77%), prolapse of genitalia (1.39%) and atypical causes like sciatic nerve paralysis (1.39%). Uterine torsion, the most common cause of dystocia in buffaloes was observed uncommon in sheep and goat. The cervix being more muscular, fibrous and tightly closed during pregnancy, accounts for cervical dystocia in ewes. Rupture of uterus was associated with previous administration of oxytocin in animals with closed cervix. Very rare foetal causes like ectopia cardis, foetal monster, pygomelia and maternal causes like sciatic nerve paralysis were also recorded.
