Nowadays ingestion of indigestible foreign bodies poses serious economic loss to domestic ruminants, especially in a developing country.
The study aims to determine the prevalence of indigestible foreign bodies in the forestomach of domestic ruminants slaughtered at Bishoftu Elfora Export Abattoir and its associated potential risk factors and identify the location and type of these indigestible foreign bodies.
On 384 domestic ruminants (171 goats, 125 sheep and 88 cattle) presented for slaughter from different zones of the region.
Cross-sectional study design was conducted from May 2021 to September 2021. Each animal was subjected to ante-mortem and post-mortem inspection by providing a unique identification number. For post-mortem examination, the forestomach was carefully removed from the abdominal cavity. For the positives, the location was properly recorded, washed, identified and photographed.
The overall prevalence of indigestible foreign bodies in domestic ruminants was 30.73% (118/384). Of these, 32.75% (56/171), 28% (35/125) and 30.68% (27/88) were recorded in goats, sheep and cattle, respectively, without statistically significant difference (p > 0.05). Aged domestic ruminants 39.3% (33/84) had poor body conditions 38.98% (23/59), originated from the Borena zone 42.11% (16/38) and were relatively recorded with higher prevalence. From the forestomach compartments, the indigestible foreign bodies were majorly found in rumen 86.43% (102/118) and reticulum 13.56% (16/118) with a statistical difference (p < 0.05).
Ingestion of indigestible foreign bodies mainly during the dry season due to shortage of forage, less biodegradable and negligent waste disposal like plastic bags attribute environmental and animal health problems and pose loss to the national economy.
如今，不可消化的异物在国内反刍动物中造成了严重的经济损失，尤其是在发展中国家。
本研究旨在确定在比绍夫图埃弗拉出口屠宰场屠宰的国内反刍动物的前胃中不可消化异物的流行情况及其相关的潜在危险因素，并确定这些不可消化异物的位置和类型。
384 只来自该地区不同地区的待宰国内反刍动物（171 只山羊、125 只绵羊和 88 头牛）。
2021 年 5 月至 2021 年 9 月进行了横断面研究设计。每只动物都通过提供一个独特的识别号码进行了生前和死后检查。死后检查时，小心地从腹腔中取出前胃。对于阳性结果，要正确记录、清洗、识别和拍照。
384 只国内反刍动物中不可消化异物的总检出率为 30.73%（118/384）。其中，山羊、绵羊和牛的检出率分别为 32.75%（56/171）、28%（35/125）和 30.68%（27/88），差异无统计学意义（p>0.05）。39.3%（33/84）的老年动物身体状况较差，38.98%（23/59）来自博雷纳区，42.11%（16/38）相对较高的患病率。从前胃室来看，不可消化异物主要存在于瘤胃 86.43%（102/118）和网胃 13.56%（16/118），差异有统计学意义（p<0.05）。
由于饲料短缺，不可消化异物主要在干季摄入，并且对塑料袋等不可生物降解的废物处理不当，导致了环境和动物健康问题，并给国家经济造成损失。
