The aim of this study was to evaluate the prevalence of uterine prolapse in cows and assess its effects on survival and subsequent fertility. Of 33,450 calving cows considered retrospectively, 216 (0.6%) developed uterine prolapse. A higher prevalence was found in beef cows (n = 57/5,700 cows, 1%) compared to dairy cows (n = 157/27,750 cows, 0.6%). Treatment consisted of cleaning and replacing the uterus with local administration of antibiotics, and applying a harness for uterine containment. The recovery rate was 81.9% (n = 177), similar in dairy (n = 129; 81.1%) and beef (n = 48; 84.2%) cows. Of the 216 cows with uterine prolapse, 18 (8.3%) died before or immediately after treatment; 21 cows (9.7%) were voluntarily culled for economic reasons (low milk yield, low fertility, insufficient weight gain). All recovered dairy cows were artificially inseminated with semen of proven fertility after a voluntary waiting period of 50 days; the beef cows were naturally mated. Among the 172 inseminated/mated cows, 84.7% (n = 150) became pregnant (83.7% dairy cows, 87.5% beef cows), while 15.2% (n = 27) did not conceive. Recurrence of uterine prolapse at subsequent calvings was recorded in one dairy cow. Based upon the data presented here, treated cows with uterine prolapse showed high chances of survival and conception, and a low risk of recurrence.
本研究旨在评估奶牛子宫脱垂的患病率，并评估其对存活率和随后生育力的影响。在回顾性考虑的 33450 头分娩牛中，有 216 头（0.6%）发生了子宫脱垂。与奶牛（n = 157/27750 头，0.6%）相比，肉牛（n = 57/5700 头，1%）的患病率更高。治疗方法包括清洁和用局部抗生素替换子宫，并应用子宫固定吊带。恢复率为 81.9%（n = 177），在奶牛（n = 129；81.1%）和肉牛（n = 48；84.2%）中相似。在 216 头患有子宫脱垂的牛中，有 18 头（8.3%）在治疗前或治疗后立即死亡；有 21 头（9.7%）因经济原因（产奶量低、繁殖力低、增重不足）被自愿淘汰。所有恢复的奶牛在自愿等待 50 天后都用经证实具有生育力的精液进行人工授精；肉牛则自然交配。在 172 头接受授精/交配的牛中，84.7%（n = 150）怀孕（83.7%的奶牛，87.5%的肉牛），而 15.2%（n = 27）未怀孕。在随后的分娩中，有 1 头奶牛再次发生子宫脱垂。根据这里提供的数据，患有子宫脱垂的治疗牛有很高的存活和受孕机会，复发风险较低。
