摘要

在埃塞俄比亚,经常性的干旱和饲料短缺加上高度的环境污染,使动物容易摄入异物。2018年11月至2019年4月采用系统随机抽样方法进行横断面研究,目的是估计患病率;确定相关风险因素,并对Gondar ELFORA屠宰场屠宰的牛体内的异物类型进行分类。采用死前和死后检查收集数据。共检查384只动物,总检出率为83只(21.61%)。在保持其他因素不变的情况下,成年动物和老年动物获得异物的几率分别是幼年动物的4.33倍(95% CI=0.98, 19.00, p=0.052)和4.54倍(95% CI=1.03, 19.96, p=0.045)。然而,对于成年牛,差异不具有统计学意义。此外,在保持其他因素不变的情况下,差体适能动物和中等体适能动物获得异物的可能性分别是好体适能动物的2.19倍(95% CI=1.04, 4.56, p=0.037)和1.51倍(95% CI=0.72, 3.13, p=0.273)。阳性病例(83例)中,瘤胃异物41例(49.40%),网状异物34例(40.96%),瘤胃和网状异物均有8例(9.64%),瓣胃异物0例(0%)。发现的异物大部分(79.51%)为非金属,包括衣服、塑料、绳子、沙子和石头。强烈建议设计和实施适当的固体废物处理和管理措施,以减少摄入难以消化的异物的风险。关键字:屠宰场;牛;异物;前胃;患病率

Fore-Stomach Foreign Bodies: prevalence, associated risk factors and types affecting cattle slaughtered at Gondar ELFORA abattoir, northwest Ethiopia
In Ethiopia, recurrent drought and feed shortage coupling with high level of environmental pollution predispose the animals to foreign body  ingestion. A cross-sectional study with systematic random sampling approach was employed from November 2018 to April, 2019 with the objectives of estimating the prevalence; identify associated risk factors and to categorize the types of foreign body in cattle slaughtered at Gondar ELFORA Abattoir. Ante-mortem and postmortem examinations were used to collect the data. From the total of 384 animals examined, the overall prevalence of foreign body was 83(21.61%). Adult and old animals were 4.33 (95% CI=0.98, 19.00, p=0.052) and 4.54 (95% CI=1.03, 19.96, p=0.045) times more likely to have a chance of getting foreign body than young animals by keeping another factors constant, respectively. However, the difference is not statistically significant for adult cattle. Moreover, poor and medium body conditioned animals were 2.19 (95% CI=1.04, 4.56, p=0.037) and 1.51 (95% CI=0.72, 3.13, p=0.273) times more likely to acquire foreign bodies than good body conditioned animals by keeping another factors constant. In the positive cases (N=83), 41(49.40%), 34(40.96%), 8(9.64%) and 0(0%) of the foreign bodies were found in the rumen, reticulum, both rumen and reticulum, and omasum, respectively. Majority of foreign bodies identified (79.51%) were non-metallic in nature, including clothes, plastics, rope,  sand and stone. Designing and implementation of appropriate solid waste disposal and management practices are strongly recommended to reduce the risk of ingestion of indigestible foreign bodies.
