can cause giardiasis and infect a variety of hosts. So far, there have been no detailed data regarding the positive rate of in cattle in China. Here, a systematic literature review was carried out to investigate the epidemiology of bovine in China. To perform the meta-analysis, the databases China National Knowledge Infrastructure, VIP Chinese Journal Databases, WanFang Databases, PubMed, and ScienceDirect were employed for screening studies related to the prevalence of in cattle in China. The total prevalence of in cattle was estimated to be 8.00% (95% confidence interval [CI]: 5.51-11.62). In the age subgroup, the prevalence of in calves (11.72%; 95% CI: 7.75-17.73) was significantly higher than that in cattle of other age groups. An analysis based on seasons showed that the prevalence of in cattle was higher in summer (9.69%; 95% CI: 2.66-35.30) than that in other seasons. The prevalence of in cattle in 2016 or later was 11.62% (95% CI: 6.49-20.79), which was significantly higher than that before 2016 (3.65%; 95% CI: 2.17-6.12). The highest prevalence of in cattle was 74.23% (95% CI: 69.76-78.45) recorded in South China. The NOAA's National Center for Environmental Information (https://gis.ncdc.noaa.gov/maps/ncei/cdo/monthly) was used to extract relevant geoclimatic data (latitude, longitude, elevation, temperature, precipitation, humidity, and climate). By analyzing the data of each subgroup, it was shown that age of cattle, sampling year, province, region, temperature, and climate were potential risk factors for giardiasis prevalence in cattle. Based on the analysis of common factors and geographical factors, it is recommended to strengthen effective management measures (e.g., ventilation and disinfection in warm and humid areas) and formulate relevant policies according to local conditions. Breeders should pay more attention to the detection of in calves, to prevent giardiasis prevalence in cattle of different ages, thereby reducing the economic losses of animal husbandry in China.
可引起贾第虫病并感染多种宿主。到目前为止，中国尚无关于牛感染情况阳性率的详细数据。在此，开展了一项系统文献综述以调查中国牛的流行病学情况。为进行荟萃分析，使用中国知网、维普中文期刊数据库、万方数据库、PubMed和ScienceDirect数据库筛选与中国牛感染率相关的研究。估计牛的总体感染率为8.00%（95%置信区间[CI]：5.51 - 11.62）。在年龄亚组中，犊牛的感染率（11.72%；95%CI：7.75 - 17.73）显著高于其他年龄组的牛。基于季节的分析表明，夏季牛的感染率（9.69%；95%CI：2.66 - 35.30）高于其他季节。2016年及以后牛的感染率为11.62%（95%CI：6.49 - 20.79），显著高于2016年之前（3.65%；95%CI：2.17 - 6.12）。中国南方记录的牛的最高感染率为74.23%（95%CI：69.76 - 78.45）。利用美国国家海洋和大气管理局的国家环境信息中心（https://gis.ncdc.noaa.gov/maps/ncei/cdo/monthly）提取相关地理气候数据（纬度、经度、海拔、温度、降水、湿度和气候）。通过对各亚组数据的分析表明，牛的年龄、采样年份、省份、地区、温度和气候是牛贾第虫病感染率的潜在风险因素。基于共同因素和地理因素的分析，建议加强有效管理措施（如在温暖潮湿地区进行通风和消毒）并因地制宜制定相关政策。养殖者应更加关注犊牛的检测，以预防不同年龄牛的贾第虫病流行，从而减少中国畜牧业的经济损失。
