目前治疗子宫炎主要采用子宫直接投药,靠自然排出,这样会造成炎性物质不能短时间内排出,所以影响奶牛正常发情配种,时间更长者造成不孕。为了验证子宫冲洗新技术治疗奶牛了宫炎的效果,试验在季节、饲养管理、病牛初始症状基本相同的情况下,用两种方法冲洗子宫治疗子宫炎并进行了对比,处理后3个月统计正常发情配种情况,结果应用新方法组牛正常发情配种率为60.71%,旧方法正常发情配种率为33.33%,新方法效果明显好于旧方法;在新方法中,对冲洗子宫后是否投药进行了对比,结果投药与不投药无显著性差异,但投药效果好于不投药,3个月后统计,投药组获68.42%的正常发情配种率,不投药组获44.44%的正常发情配种率,建议生产上采用新方法冲洗子宫后进行投药处理,但要选择安全性高的药品,尽量不要影响牛奶的生产。 相似文献

奶牛子宫炎严重影响奶牛养殖者的积极性,目前已有的提高发情率的措施效果欠佳。笔者对101头被诊断为子宫炎的奶牛进行子宫冲洗,并在冲洗后灌注剂量分别为10 m L、20 m L以及40 m L的土霉素子宫注射剂,对其发情率进行研究。试验结果表明:冲洗后灌注土霉素子宫注射剂的剂量对发情率影响不大,灌注剂量10 m L,平均发情率达到69.8%;灌注剂量为20m L,平均发情率达到67.72%;灌注剂量为40 m L,平均发情率达到66.77%,3组无显著性差异(P0.05)。本试验研究表明,冲洗子宫后注入药物用量可以适当减少,这样除了可以降低成本外,还能减轻子宫负担。在试验中,冲洗后灌注10 m L土霉素子宫注射剂也收到了很好的效果,可以大范围推广。 相似文献

奶牛子宫内膜炎研究进展 总被引：1，自引：1，他引：0
子宫内膜炎是奶牛中一种常见的产科疾病,它可引起奶牛不孕,给奶牛养殖带来严重经济损失。引起奶牛子宫内膜炎的主要原因可概括为理化性和生物性二类,病原菌的侵入可通过上行性感染和下行性感染的途径造成子宫炎的发生,主要致病菌有葡萄球菌、大肠埃希菌、链球菌等。直肠检查和内窥镜检查仍是奶牛子宫内膜炎的常规的诊断方法,但仍有待于探索简便准确的新诊断方法。恢复子宫张力,促进子宫血液循环和炎性分泌物排出,抑制或消除子宫内感染病菌是子宫内膜炎的主要治疗原则,常用的治疗方法有冲洗子宫,全身疗法,抗生素和激素疗法以及中药治疗等。创建新的治疗和诊断方法,开发疗效好的药物将是提高奶牛子宫内膜炎诊疗水平的努力方向。 相似文献

Subacute ruminal acidosis in dairy cows occurs when ruminal pH is below about 5.5. However, the exact threshold level of ruminal pH affecting cow health is still in debate. This investigation was carried out in 505 cows within 31 farms. The postpartum disorders, including dystocia, retained placenta, anestrus, cystic ovary, metritis, clinical mastitis and lameness, were analyzed. Ruminal pH, serum beta‐hydroxy butyrate (SBHB), serum urea nitrogen and body condition score (BCS) were measured once during the 3 to 6 weeks postpartum, while BCS was determined once more at 1 week before calving. Ruminal pH was determinded by ruminocentesis technique. The ruminal pH was evaluated to study the association with BCS, SBHB and postpartum disorders using linear regression in a generalized linear mixed model with farm as a random effect. The results show that low ruminal pH was associated with dystocia, metritis and lameness. Moreover, a low ruminal pH can be found in cows with a high loss of BCS after calving and also in cows with low SBHB postpartum. These findings confirmed the feasibility of the ruminocentesis technique and the association of low ruminal pH on various postpartum disorders at the individual cow level. However, the consequences of low ruminal pH on dairy cow health still needs more exploration for a better understanding of the physiological mechanisms. 相似文献

This paper reviews the causes, impact, treatment, and prevention of retained placenta (RP), metritis, and endometritis in dairy cows. The occurrence of each of these diseases largely depends on immune function in the transition period. Retained placenta affects 5-10% of calvings and greatly increases the risk of metritis and endometritis. More field studies are needed to validate criteria for treatment of metritis, but cows with at least two of RP, fever, dullness, and fetid uterine discharge appear to merit treatment with systemic antibiotics. Clinical endometritis affects 15-20% of cows at 4-6 weeks postpartum; an additional 30-35% have subclinical endometritis between 4 and 9 weeks postpartum. Under specific conditions, treatment of cows with endometritis improved pregnancy rate. Systematic use of prostaglandin F(2alpha) at 5 and 7 weeks postpartum may improve pregnancy rate. The economic benefit of efforts to identify and treat endometritis is herd-specific. 相似文献

Delayed conception is defined as an interval of greater than 90 days postpartum before a cow becomes pregnant again. In this study, the risk factors for delayed conception in Korean dairy herds were determined by evaluating several reproductive factors in individual cows. The following data was recorded from 1,012 pregnancies in eight dairy herds (designated A-H) from July 2001 to June 2006: herd, cow parity, repeated animal (cows included 2, 3, or more times), calving season, calving condition (abnormal partus), postpartum disorders (retained placenta, metabolic disorders, metritis and ovarian cysts) and conception. Logistic regression was used to evaluate the effects of these factors on delayed conception. A stepwise procedure was used to obtain the appropriate model (α = 0.05), which revealed the herd, metritis and ovarian cysts to be significant risk factors for delayed conception. The odds ratio showed that the likelihood of delayed conception increased by 3.3 and 2.0 fold for each incidence of metritis and ovarian cysts, respectively. Delayed conception was significantly more likely in 2 herds, in herd A by 2.0 fold and in herd B by 2.4 fold, compared with herd H. These results suggest that the prevention of postpartum metritis and ovarian cysts, as well as improved herd management, will be needed to maintain a short interval between calving and conception in Korean dairy herds. 相似文献

Based on information from USDA National Animal Health Reporting System early State pilot studies and more recent national studies, the cost of reproductive diseases and conditions was estimated for beef and dairy cattle. We estimate the total yearly cost of female infertility, abortions/stillbirths, dystocia, retained placentas, and metritis/pyometra to be $441 to $502 million for beef producers and $473 to $484 million for dairy producers with an aggregate national total of approximately $1 billion annually. This loss is over six times more costly than that resulting from respiratory diseases. Three-fourths of the cost for reproductive diseases and conditions can be attributed to female infertility and dystocia and the failure to produce a healthy calf that will survive the first 24 h of life. Aggregate national costs are roughly evenly divided between beef and dairy; per cow costs are more than three times greater for dairy cows ($52.60) than for beef cows ($14.00). Approximately equal national costs are attained because there are more than three times more beef cows than dairy cows. One factor contributing to the greater cost for dairy cows is lost milk production associated with dystocia and retained placentas. Lost milk production accounts for one-third of the costs associated with reproductive diseases and conditions in dairy cattle. We conclude from this review and our resulting estimates that focusing on developing strategies to increase the probability of conception, minimize dystocia, and produce a healthy calf that survives beyond the first 24 h of birth must continue to receive high priority in both dairy and beef cattle management and research. 相似文献
