| 摘 要： | 目的]难产是繁殖母牛的常见疾病,危害母牛和犊牛健康,进行难产牛原因分析有助于兽医或者牛场做好接产工作,提高生产力。
方法]在万方数据服务平台、CNKI中国知网、Elsevier SD数据库和“SCI-科学引文索引”上,用关键词“难产”、“病例”、“牛”精确搜索我国相关的案例,统计筛除后的病例数,对牛难产原因进行统计和分析。
结果]检索获得母牛难产的病例总数为753例,难产原因占比最大的是胎儿性难产有525例,占69.72%(95%CI 66.3-73.0);其次是产道异常（骨折造成骨盆畸形,子宫颈、阴道、阴门狭窄造成的产道异常）造成的难产89例,占11.82%(95%CI 9.6-14.3);阵缩及努责无力造成的难产41例,占5.44%(95%CI 3.9-7.3);子宫扭转造成的难产38例,占5.05%(95%CI 3.6-6.9);子宫颈开张不全造成的难产26例,占3.46%(95%CI 2.3-5.0);营养不良造成的难产18例,占2.39%(95%CI 1.4-3.8);双胎难产9例,占1.20%(95%CI 0.5-2.3);人为因素和其他因素造成的难产有7例,占0.93%（95%CI 0.4-1.9）。
结论]引起母牛难产的最主要的因素是胎儿性难产、产道异常。兽医在实际临床中,应快速、准确确定母牛难产的病因,采取对应接产措施,减少经济损失。

| Abstract: | Objective]Dystocia is a common disease in breeding cows, which not only harms the health of cows, calves, but also leads to the decrease of reproductive ability and development of the cattle industry..
Methods]On Wanfang data, CNKI , Elsevier SD database and Web of Science, the relevant cases in China were searched accurately with the keywords "dystocia", "case" and "cattle". The number of cases after screening was counted, and the causes of cow dystocia were counted and analyzed.
Results]The total number of cases of dystocia in cows was 753. The most common cause of dystocia was fetal dystocia in 525 cases (69.72% (95%CI 66.3-73.0)), followed by abnormal birth canal (pelvic deformity caused by fracture, abnormal birth canal caused by cervical, vaginal and vaginal stricture) in 89 cases (11.82% (95%CI 9.6-14.3)).There were 41 cases of contraction and weakness, accounting for 5.44% (95%CI 3.9-7.3), 38 cases of uterine torsion, accounting for 5.05% (95%CI 3.6-6.9), 26 cases of incomplete opening of cervix, accounting for 3.46% (95%CI 2.3-5.0), 18 cases of malnutrition, accounting for 2.39% (95%CI 1.4-3.8), 9 cases of twin dystocia, accounting for 1.20% (95%CI 0.5-2.3), and 7 cases of dystocia caused by human and other factors, accounting for 0.93%(95%CI 0.4-1.9). And most of the cases are concentrated in Guangxi, Yunnan, Heilongjiang and Jilin. Basically all cows can survive, but the survival rate of calves varies greatly due to different causes of dystocia.
Conclusion] The main factors causing cow dystocia are fetal dystocia and abnormal birth canal. In clinical practice, veterinarians should quickly and accurately determine the cause of dystocia in cows, and take corresponding delivery measures to reduce economic losses. |
