Comparative clinical and epidemiological characteristics, risk factors, and outcomes of uterine torsion in camels, buffaloes, and cattle: a multicenter study

Background: Uterine torsion is a leading cause of dystocia in large domestic animals. However, there is no systematic comparison of its clinical presentation, epidemiological data, risk factors, or outcomes in camelids, buffalo, and cattle. Methods: ) were examined. Detailed clinical records from 80, 262, and 129 diagnosed torsion cases were examined for parity, torsion characteristics, intervention methods, and survival outcomes. Logistic regression models were used to determine risk factors for fetal and maternal mortality. Results: < 0.001), with multiparous females being more likely to experience it. Gestational timing, torsion direction, anatomical location, and severity all differed significantly between species. Torsion occurred primarily during parturition in camels and cattle, but was evenly distributed between late gestation and parturition in buffaloes. Despite left-horn pregnancies, camels exhibited almost exclusively right-sided torsion, whereas buffaloes and cattle exhibited torsion in the direction of the gravid horn. Camels (96.3%) and buffaloes (98.6%) had more post-cervical torsion, whereas cattle had a higher rate of pre-cervical torsion (35.7%). Camels had the highest percentage of severe torsion (85.0%), buffaloes had severe (45.8%) and moderate (48.9%) torsions, and cattle had moderate (67.4%) to mild (24.8%) torsions. Severe torsion and delayed intervention (>48 h) were the strongest risk factors for fetal and maternal mortality across all species. Conclusion: This study reveals significant species-specific differences in the clinical presentation and epidemiology of uterine torsion. The identified patterns in timing, direction, location, and severity provide critical evidence for developing tailored diagnostic and management strategies in camels, buffaloes, and cattle.
