牛乳腺炎是影响全球奶牛的最常见和流行的疾病之一。它对牛奶生产的质量和数量产生不利影响,并给农民带来巨大的经济损失。
■本文旨在通过系统评价和荟萃分析来评估中国大陆临床乳腺炎(CM)感染的患病率。1983-2022年期间从数据库中以英文或中文发表的研究报告(PubMed,谷歌学者,科克伦图书馆,科学直接,WebofScience,中国科技期刊VIP数据库(VIP),中国国家知识基础设施(CNKI),和万方数据库)是在查阅相关科学文献后确定的。根据我们的入选标准,这项研究分析了47项已发表的研究中CM的患病率,患病率从现有研究中提取了感染CM的牛的总数,使我们能够估计中国大陆这些人群中CM感染的患病率。
■临床乳腺炎的合并患病率与95%CI为10%(95%CI:9.00,12.00)。大多数CM与泌乳有关,奇偶校验,和年龄,与泌乳早期8%(95%CI:5.00,10.00)相比,泌乳晚期15%(95%CI:11.00,18.00)和泌乳中期10%(95%CI:6.00,13.00)的患病率更高。CM的发病率随着胎次和年龄的增加而明显增加,最高的发病率分别为19%(95%CI:15.00,23.00)和16%(95%CI:12.00,19.00)在胎次和年龄≥7岁。在季节中,秋季CM感染率最高,为9%(95%CI:2.00,17.00)。有趣的是,关于季度对CM患病率的影响,没有明显的影响。
■因此,估计中国大陆牛群中CM的患病率。通过荟萃分析可以提供足够的措施来控制CM,减少经济损失,并防止CM在中国牛群中的传播和传播。
UNASSIGNED: Bovine mastitis is one of the most common and prevalent diseases affecting dairy cattle worldwide. It adversely affects the quality and quantity of milk production and leads to a significant economic loss for the farmers.
UNASSIGNED: This article aimed to estimate the prevalence of clinical mastitis (CM) infection in mainland China using a systematic review and meta-analysis. The research reports published during 1983-2022 in English or Chinese from databases (PubMed, Google Scholar, Cochrane Library, Science Direct, Web of Science, VIP Database for Chinese Technical Periodicals (VIP), Chinese National Knowledge Infrastructure (CNKI), and Wan Fang database) were identified after reviewing the relevant scientific literature. Based on our inclusion criteria, this study analyzed the prevalence of CM in 47 published studies prevalence extracted the total number of cattle infected with CM from the available studies, allowing us to estimate the prevalence of CM infection among these in mainland China.
UNASSIGNED: The pooled prevalence with the 95% CI for the clinical mastitis was 10% (95% CI: 9.00, 12.00). The majority of CM was associated with lactation, parity, and age, with higher prevalence observed in late lactation 15% (95% CI: 11.00, 18.00) and mid-lactation 10% (95% CI: 6.00, 13.00) in comparison to early lactation 8% (95% CI: 5.00, 10.00). The incidence of CM increased significantly with the increase of parity and age, and the highest incidence rates were 19% (95% CI: 15.00, 23.00) and 16% (95% CI: 12.00, 19.00) at parity and age ≥7, respectively. Among the seasons, the highest prevalence of CM infection was found in autumn 9% (95% CI: 2.00, 17.00). Interestingly, no significant effects were evident regarding the influence of quarter on the prevalence of CM.
UNASSIGNED: Thus, estimating the prevalence of CM among cattle in mainland China. through meta-analysis can provide adequate measures to control CM, reduce economic losses, and prevent the spread and transmission of CM in Chinese herds.
