Abstract
A cross-sectional study was conducted from October 2016 to April, 2017 at Bahirdar municipal abattoir, Amhara National Regional State, to determine the prevalence of rumen and reticulum foreign bodies and to identify types of foreign bodies and associated risk factors for the occurrences of foreign bodies. The study animals were selected by using simple random sampling method from the total slaughtered animals. From the total of 384 examined cattle, 78 (20.3%) were found positive for the occurrence of indigestible foreign bodies in rumen and reticulum. Prevalence of foreign body occurrence recorded in young (<5 years) 10 (11.23), adult (5-10 years) 34 (15.38%) and in old (>10 years) 34 (45.95%) respectively while the prevalence rate recorded in poor, medium and good cattle were 33 (35.48%), 29 (22.3%) and 16 (9.93%). The types of foreign bodies encountered in rumen and reticulum were plastic, nails, wires, hair ball, clothes and key. Out of 78 positive cases of foreign body, 51 (13.5%) were occurred in rumen, 21 (5.5%) in reticulum and 6 (1.5%) were encountered in both rumen and reticulum. Among the considered risk factors, age, stomach compartment and body condition score of the examined animals found highly significantly associated (p<0.05) with the occurrence of foreign bodies. The prevalence of rumen and reticulum foreign bodies was lower in local breed cattle 57 (19.38%) than that of the cross breeds 21 (23.3%). It was not stastically significant (p=0.999) between local and cross breed. In general, detection of the foreign bodies in rumen and reticulum causes loss of production and high mortality rate as well it has also impact on animal welfare. Hence, appropriate solid waste disposal system need to be implemented in the study area to prevent health risk of ruminants and environment.

Cattle play significant contribution in Ethiopian economy as a source of meat, milk, drought power, income, and foreign exchange
From the total of 384 cattle examined for the presences of any foreign bodies 78 (20.3%) animals had foreign bodies in their rumen and/or reticulum
The present study revealed an overall prevalence of 78 (20.3%) of rumen and reticulum foreign body in cattle slaughtered at Bahirdar Municipal abattoir
Summary
Cattle play significant contribution in Ethiopian economy as a source of meat, milk, drought power, income, and foreign exchange. Sheep and goats are major source of income (cash) for the rural poor farmers in most parts of tropics including Ethiopia. They play an important role in providing export commodities, such as live animals, hides and skins to earn foreign exchanges [1]. The ingestion of foreign body is mainly related with nutritional deficiencies and feeding management and cause various problem in different organ of the animal, mainly in rumen and reticulum [7]. TRP relatively common disease in cattle caused by the ingestion of foreign bodies in the reticulum swallowed metallic objects such as nail or pieces of wire fall directly on the reticulum or pass into the rumen and subsequently carried over the rumeno-reticular folds in to the cranioventral part of the reticulum [8]
