\begin{abstract}
        


A cross-sectional study was conducted from October 2016 to July 2017 on ovine slaughtered at Jimma municipal abattoir with the aim of identifying main pathological lesions causing organs and carcass condemnation, and associated direct financial losses. In this, 384 sheep were recruited to the study using systematic random sampling and standard antemortem (AM), and postmortem inspection (PMI) procedures were employed. Nasal discharge, tick infestation, coughing, lameness, emaciation, depression and salivation are recordedas the major AM findings of the current study.

\section[{I. Introduction}]{I. Introduction}\par
he livestock sector globally is highly dynamic, contributes 40\% of the global value of agricultural output and support the livelihoods and food security of almost a billion people \hyperref[b52]{(Thornton, 2010)}.\par
Within African society, small ruminant comprises a greater proportion of the total wealth of the rural families, because of the low input requirements such as low initial capital, fewer resources and maintenance cost. They are also able to produce milk and meat in readily usable quantities using marginal lands and poor pasture and crop residues. Furthermore, their production cycle makes them need only short periods to reconstitute flocks after a disaster and respond quickly to the demand (Genet by, 1991). Ethiopia is the leading African country in livestock population, having around 34-40 million TLU (Tropical livestock unit) out of which 17\% and 12\% cattle and small ruminants, respectively, are found in Ethiopia (Ministry of information (MOI), 2005).According to  {\ref (Development, ppStatis, 2009)}, the population of sheep and goats in Ethiopia is estimated to be 26.1 and 21.7 million respectively. It was the third largest number of sheep and goat among African nations and rank eighth in the world  {\ref (Alemu and Merkel, 2008)}.\par
They generate cash income from export of meat, edible organs, skins and live animals \hyperref[b29]{(Ibrahim, 1998)}. There is also a high domestic meat demand from these animals, particularly during religious festivals. Even though this sub-sector contributes much to the national economy, its development is hampered by various constraints. These include endemic animal diseases, insufficient nutrition, poor husbandry, and lack of sufficient infrastructure, trained labor and government policies \hyperref[b46]{(PACE, 2003)}. Each year a large loss results from the death of animals and weight loss during transportation; and condemnation of edible organs and carcasses at slaughter.\par
Abattoir meat inspection is essential to remove gross abnormalities from meat and its products, to prevent the distribution of contaminated meat and to assist detecting and eradication of certain livestock diseases. More specifically, ante mortem inspection attempts to avoid introduction of clinically diseased animals into slaughter house and also serves to obtain information that will be useful in making sound post mortem inspection. Likewise, postmortem inspection is the center around which meat hygiene revolves since it provides information essential for evaluation of clinical signs and pathological process that affect the wholesomeness of meat \hyperref[b27]{(Herenda, et al., 1994)}.\par
As the meat is the sources of protein to a human being, it should be clean and free from diseases of particular importance to the public such as tuberculosis and cysticercosis. Meat is also condemned at slaughterhouse to break the chain of some zoo noses which are not transmitted to man directly via meat like hydatidosis and other important diseases of animals such as fasciolosis \hyperref[b3]{(Arbabi and Hooshyr, 2006;} {\ref Fufaet al., 2010)}.\par
Each year a significant economic loss results from mortality, poor weight gain, condemnation of edible organs and carcasses at slaughter. This production loss in the livestock industry is estimated at more than 900 million USD annually \hyperref[b30]{(Jacob, 1979;}\hyperref[b0]{Abebe, 1995;} {\ref Jobreet al., 1996)}. The major causes of pathological lesion during PMI of slaughtered ovine at abattoir are the disease caused by parasites, bacterial and other abnormalities. The final judgment as to action to be taken with an organ, the carcass or part of a carcass is based on the total evidence produced by the visual observation, palpation and incision \hyperref[b51]{(Teka, 1997)}.\par
Abattoir data is an important option for observing the diseases of both economic and public health importance \hyperref[b3]{(Arbabi and Hooshyr, 2006;}\hyperref[b20]{Fufa, et al., 2010)}. Nowadays, several modern abattoirs like: HELMEX, ELFORA, Metehara, Modjo and Luna are established in Ethiopia. This increase in a number of slaughterhouse shows that increase in demand for meat supply, but the provisions have been challenging due to diseases, production problems and other factors. Given this, proper evaluation of financial losses due to organ condemnation resulting from various diseases at abattoirs is needed \hyperref[b17]{(Ezana, 2007)}. It is necessary to have enough information on a pathological lesion that causes organs and carcass condemnation at the abattoir. Hence, having information on where and how to reduce the losses that may be caused by the various abnormalities (lesions/pathology). Various studies  {\ref (Jembere, 2002;}\hyperref[b56]{Yimam, 2003;}\hyperref[b4]{Aseffa, 2005;}\hyperref[b21]{Get chew, 2008;} {\ref Regessaet al., 2013)} were carried out in the country in this regard to know the causes and losses associated. However, in Jimma there are no recorded studies conducted on major causes and financial losses associated with organs and carcass condemnation along with survey on pathological lesions. Therefore, the objectives of this study were to: ? Identify major pathological lesions causing organs and carcass condemnation in slaughtered sheep at Jimma municipal abattoir and, ? Estimate the direct financial losses attributed to condemned organs and carcass in sheep. 
\section[{II. materials and methods}]{II. materials and methods} 
\section[{a) Study Area}]{a) Study Area}\par
The study was conducted from November 2016 to July 2017 at Jimma municipal abattoir in Jimma zone.\par
Jimma two is found in Oromia region south-western part of Ethiopia at a distance of 346 km away from Addis Ababa and lies between 36°50´E longitude and 7°40´N latitude atan average elevation of 1750 meter above sea level. Jimma is the largest city in south-western Ethiopia. It is special zone of the Oromia Regional state and is surrounded by different Jimma woreda. The climate of the area is characterized by humid tropical with bimodal heavy rainfall which is uniform in amount and distribution, ranging from 1200 to 2800 mm per year, with short and main seasons occurring from mid-February to May and June to September, respectively. The rainy season extends from mid-February to early October. Temperatures at Jimma are in a comfortable range, with the daily mean staying between 20°C and 25°C year-round. The total human populations of Jimma town was about 174, 446(88, 766 males and 85, 680 females). The livestock population of the area was reported to be about  
\section[{b) Study Population}]{b) Study Population}\par
The study animals were sheep brought Jimma municipal abattoir and destined for slaughter. All animals were male and belonged to indigenous breeds kept under extensive management system. Sheep destined for slaughter had come from different parts of the weredas in the Jimma zone such as Dedo, Serbo, Saqa and Bilida inspected by standard AM, and PMI. 
\section[{c) Study Design}]{c) Study Design}\par
A cross-sectional study using systemic random sampling technique was conducted from December 2016 to April 2017 to determine the pathological lesion that causes organs and carcass condemnation and to estimate the magnitude of direct financial loss attributed in sheep slaughtered at Jimma abattoir. 
\section[{d) Sampling Method i. Sample size determination}]{d) Sampling Method i. Sample size determination}\par
In this study, systematic random sampling method was applied to include study animals, and study animals were grouped into young (under 1 years and three months) and adult above this based on the eruption of one or more incisor teeth according to Vattaet al.  {\ref (2005)}.Since there was no published work on lesion survey from Jimma abattoir, 50\% expected prevalence is considered to calculate the total sample size with 95\% CI, 5\% level of precision (Thrush field, 2007). The sample size was 384 and determined using the formula given by N= 1.96 2 P exp (1-P exp ) d 2 Where N= required sample size, P exp = expected prevalence and d is desired absolute precision. Accordingly, the total sheep included in the study were 384. 
\section[{e) Abattoir Survey}]{e) Abattoir Survey}\par
In the cross-sectional study of active abattoir survey, both AM and PMI were carried out in accordance by the procedures of Ethiopian Meat Inspection Regulation \hyperref[b7]{(Belina and Melese, 2017)}.\par
i. Ante-mortem Inspection (AMI)\par
The AMI (pre-slaughter examinations) of ovine was conducted at lairage both in motion and at rest and information related to study variables such as the behavior of an animal, age, BCS and origin and were recorded. At the same time, various signs of diseases and abnormalities were inspected with physical animal examination and its judgment were approved, conditionally approved, detained and rejected. Study animals were grouped into young and adult age groups according to standard dentation method  {\ref (Vattaet al., 2005)}.\par
ii 
\section[{. Post Mortem inspection (PMI)}]{. Post Mortem inspection (PMI)}\par
During PMI all internal organs (liver, lungs, heart, kidney, gastro-intestinal tract), and carcasses were thoroughly inspected by visualization, palpation and making systematic incisions for the presence of cysts, parasites and other abnormalities. Pathological lesions were differentiated and judged according to guidelines on meat inspection for developing countries as totally fit for human consumption, and conditionally approved, and totally or partially condemned when unfit for human consumption \hyperref[b18]{(FAO, 1993)}. 
\section[{f) Assessment of direct Financial Loss}]{f) Assessment of direct Financial Loss}\par
In the current study, the total financial loss due to organs and carcass condemnation was computed by considering the condemnation rate or percentage of each edible organ and carcass, average number of animals slaughtered in the abattoir per year from retrospective data of the abattoir. The average weight of each organ and carcasses in kg, average current local market price of major organs and carcass, and each condemned organ was counted to estimate the financial loss. The average current local market price of each organ and mutton was collected by questionnaire from the butcheries in Jimma town for ease of computing the loss.\par
The retail average market prices obtained from butcher shops found in Jimma town in ETB were: Liver=30, lung=20, kidney=15, heart=18, GIT=90 ,whole carcass=4000 and mutton =150ETB/kg. In the case when there was whole carcass plus organs (whole body) rejection at PM, the average price of sheep came for slaughter was considered (4,000 ETB). The direct loss is calculated according to the procedures described by Ogurinade and Ogunrinade (1980), and the formula: LOS is direct annual financial loss due to organs and carcass loss, MAK is annual average number of sheep slaughtered at Jimma abattoir, PL is overall prevalence of lesion, Pi is prevalence of each organ and carcass condemned, C i is average market price of each organ and 1kg mutton at butcher shops of the Jimma town.\par
The direct financial loss was expressed in US Dollar (\$) based on the current currency exchange rate of 1 USD = 22.5 Ethiopian Birr (ETB). 
\section[{g) Data Analysis}]{g) Data Analysis}\par
The active abattoir data, and questionnaire survey were entered into Microsoft Excel-2016 spread sheet and the process of coding, cleaning and validating was done on this sheet and analyzed using SPSS version 20. For the data from PMI, descriptive statistics were used to determine organ and carcass condemnation rates, defined as the proportion of organs and carcasses condemned to the total number of organs and carcasses examined. Each financial loss was also calculated. Possible variation between rejection rates of specific organs, age groups and origin, were taken into consideration.

Detail AMI was conducted on a total of 384 sheep destined for slaughter at Jimma municipal abattoir and47 (12.2\%) of ovine were found to have different abnormalities. Nasal discharge, coughing, tick infestation, depression, emaciation, and lameness were those frequently observed among signs of diseases encountered in both age groups. The result also showed 6\% (23/384) animals were conditionally passed for slaughter because of abnormalities such as lameness, respiratory problem, and their collection with tick infestation. On the other hand2\% (8/384) sheep were unfit for human consumption and rejected during AMI. Since, they showed two and more signs of diseases such as emaciation with nasal discharge and depression1 \%( 4/384), salivation and salivation with coughing 1 \%( 4/384) were the major cause of rejection (Table \hyperref[tab_1]{1}).\par
The AMI result also depicted of 28 sheep with poor body conditions 46.43\% were found to have one or more sign/s of illness whereas in those with good BCS In the current study, four different decisions were passed as AM judgments where apparently healthy sheep were passed for slaughter (91\%), and others showed mild signoff illness and conditionally approved (6\%) whereas 2.9\% of sheep were detained and rejected as unfit for slaughter. Rejection rate was significantly higher (p ? 0.05 ) in young animals with poor BCS than in adult animals with good and medium BCS (Table \hyperref[tab_2]{2}).   ii. Postmortem Inspection (PMI) Among animals that had been examined during AMI 373 were slaughtered and subjected to through PMI following standard postmortem procedure and a total of192gross pathological lesion leading to partial and total condemnation of organs and carcasses were recorded. Among these abnormalities, lesions were frequently encountered from liver; and of which Cyst cercus teniculosis (34\%) and calcification accounted 25.5\%. These followed by abscess (13.8\%), hepatitis (10.6\%), cirrhosis (7.4\%) and hydatid cyst (7.4\%), fasciolosis (5.3\%) and stelezia hepatica (3.2\%).\par
A total of 56 lungs were also condemned as they were affected by teniculosis (35.7\%), Hydatid cyst (21.4\%), marbling lesion (17.8\%), Emphysema and calcification (16\%), pneumonia (12.5\%), abscess (3.6\%) and 5\% with unidentified lesions. In this study abscessation was also inspected in other organs like heart, kidney and GIT, and carcass (Table \hyperref[tab_3]{3}).\par
Out of a total of 11 hearts condemned (Table \hyperref[tab_4]{4}), hydatid cyst and pericarditis recorded as major causes contributing 45.5\% and 36.4\% which followed by abscess (18.2\%) and discoloration (0.9\%). Renal problems were observed in 11 kidney examined and 54.5\% found to be caused by abscess whereas 27.3\% and 18.2\% were due to calcification and nephritis and other unidentified causes, respectively.13 GITs were also encounter as with abnormalities like cyst cercus teniculosis and abscess and foreign bodies, and they were subjected to total and partial condemnation accordingly.\par
The major pathological conditions for carcass rejection from local market were bruising accounting for 42.9\%. Out of 7 rejections judgments2 were totaland the rest 5 were partial (Table  {\ref :} 3; and 4).  There was a condition of examining, a single to multiple lesions per organ e.g., we examined teniculosis and Calcification from a single liver; and all are recorded as different lesions.\par
*=Whole carcass plus organs totally rejected at PM; except in carcass, PC indicates 50\% loss. 
\section[{b) Assessment of Direct Financial Losses}]{b) Assessment of Direct Financial Losses}\par
The direct financial loss was computed based on average cost/ price of individual condemned organs and carcasses during the study period, applying the formula given by Ogurinade and Ogunrinade (1980). The study indicated that there had been a total loss of 12,729,960ETB which is 56,576 Undue to a partial and total condemnation of organs and carcass at slaughterhouse annually. The study result also indicated there was a total condemnation of 2 (1.3\%) whole carcasses (carcass plus organs) (Table \hyperref[tab_4]{4}). For the calculation, alive price of one sheep is considered as 4000ETB for total carcass condemnation. 
\section[{IV. Discussions}]{IV. Discussions}\par
The AM and PM inspections were conducted in the abattoir for the purpose of identifying an abnormality and removing animals' products with pathological lesions which were unsafe for human consumption and having poor aesthetic values (Van Llogtestijn, 1993; Grace yet al., 1999).\par
In this research, out of 384 study animals 11 (2.9\%) were rejected and detained as unfit for human consumption suspecting different zoo notic diseases such as rabies in the case of salivation with high fever and tuberculosis in animals with a sign of emaciation with high coughing, depression and nasal discharge. Similarly, suspecting rabies in the case of salivation and bovine TB in animals with sign of emaciation with high depression and coughing was reported by  {\ref Belina and Melees (2017)}. \hyperref[b48]{Radostits et al., (2000)} stated that in domestic ruminants, cobalt deficiency results in appetence and loss of body weight, emaciation, weakness, decreased growth, unthrifty appearance, diarrhea, and anemia. Again during the AMI, 23(6\%) of sheep were found to be showing signs of abnormalities such as lameness, tick infestation along with coughing and nasal discharge frequently encountered and passed with judgments of conditional approval where due attention was given for whole body part and specific organ at postmortem examinations.\par
One of the causes of lameness was trauma caused by hitting with a thick stick during driving to abattoir on foot and inappropriate vehicles and loading and off-loading negligence during transportation to marketplaces and to the abattoir. During the AM examinations, it was found that respiratory disorders were higher than other abnormalities encountered during the AMI 14(3.7\%) nasal discharge and 5(1.3\%) coughing. The respiratory signs such as the presence of nasal discharge and coughing were most probably related to stress due to lack of feed and water that may lead to immune suppression enhancing opportunistic pathogens. On the other hand, overcrowding during transportation is also a source of stress (Get chew, 2008). In agreement to the current study, coughing, depression and lameness are frequently observed abnormalities encountered during AMI (Man defroet al., 2015) at Elfora Export Abattoir, Ethiopia.\par
The rejection rate was significantly higher (p<0.05) for those poor body conditions than good and medium body conditions (Table \hyperref[tab_2]{2}). Because of poor BC by itself may be due to unidentified abnormalities that increase rejection probability. Jibatet al. (2008) studied and determined the rate of organs and carcasses condemned and the associated annual financial loss at HELMEX abattoir in Ethiopia and they reported out of 2688 sheep and goats examined 188(7\%) carcasses were condemned due to poor body condition cases.\par
On the other hand, there was a significant difference (p=0.051) within the age groups of animals in rejection at AM more young than the adult which were 3.2\% (6/185) and 1\% (2/199) respectively. It may due to difficulty in protection from stress, shortage of feed and water, not getting enough rest. \hyperref[b28]{Herenda et al. (2000)} stated that leanness (Poorness) is often observed in case of poor quality pasture and young growing animals which have had protein-deficient diet.\par
In the present study, organ condemnation rate showed that, liver and lung were the most frequently affected organs with the highest condemnation rate followed by GIT, kidney and heart and carcass significantly (p=00), which is 94(48.9\%), 56(29.2\%), 13(6.8\%), 11(5.7\%), 11(5.7\%) and 7(3.6\%) respectively. This finding is in agreement with reports of \hyperref[b8]{Cadmus and Adesokan (2009)} who recorded that lungs (45.7\%) and the liver (32.9\%) were the most affected organs with the kidney (0.02\%) and the heart (0.01\%) being the least. The current study introduced that parasites are the major causes of organ condemnations. Parasitic causes like, Cyst cercus teniculosis, hydatidosis, fasciolosis and Stelezia hepatica were found to be the major parasitic conditions responsible for organ condemnation. There was no statistical difference in the rate of organ and carcass condemnation from parasitic infestation considering the age and origin of animals. This shows that parasitic diseases of sheep are widely spread in all age groups and everywhere in the country.\par
The presence of small ruminant hydatidosis at slaughterhouse has been documented in Ethiopia.  {\ref (Bekeleet al., 1988)} reported a prevalence rate of 16.4\% in sheep which is higher than the finding in this study (7.4\%). Similarly  {\ref (Jobreet al., 1996)} reported prevalence rate of 11\% and 6\% from South Omo and DebreZeit slaughterhouses, respectively in sheep and goats.\par
In present finding, hydatid cysts were more frequently observed in lungs than liver of sheep (6.3\%) and (3.6\%) respectively. Additionally, similar findings were also reported by different authors  {\ref (Khanet al., 2001} {\ref , Dalimaiet al., 2002} {\ref , Daryaniet al., 2007)}. However, the most common site for hydatid cyst was the liver followed by the lungs in the Middle East  {\ref (Kamhawiet al., 1996)}. Lungs are most commonly affected by hydatidosis because at old age the liver capillaries are dilated, and most cysts passed directly to the lung. Secondly, the cyst passes to the lung via the thoracic duct without involving the liver \hyperref[b25]{(Gracey, 1986)}. And also, many researchers reported that liver and lung are the most commonly affected organs by hydatid cyst \hyperref[b1]{(Abunna and Hordofa, 2013;}\hyperref[b13]{Denbarga, 2011;}\hyperref[b33]{Jobre, 1996)}. The reason being that lung, and liver contain highest capillary bed in the body and therefore, the majority of the oncospheres were filtered out and trapped in the fine blood capillaries and only small number of oncospheres reaches the remaining organs \hyperref[b25]{(Gracey, 1986)}. In present study also lungs and liver 12(6.3\%) and 7(3.6\%) respectively, were affected by hydatidosis.\par
Out of 94 condemned liver teniculosis is the most frequent cause of organ lesion (34\%) followed by calcification (25.5\%), abscess 13(13.8\%), hepatitis 10(10.6\%), cirrhosis 7(7.4\%), discoloration 4(4.3\%), more than 3 lesion on liver 3(3.2\%) and parasites like teniculosis, Stelezia hepatica, Fasciola species and hydatid cyst were found to be the major causes that rendered liver rejection from the local market (Table \hyperref[tab_3]{3}). Fascioliasis constitutes both economic and public health constrains to ruminant production. It is caused by two trematode species, Fasciola hepatica and F. gigantica, which develop in different livestock species mainly sheep and cattle; but, also in many other domestic herbivores \hyperref[b24]{(Gracey, and Collins, 1992)}. The reported prevalence of Fasciolaspp. (5.3\%) was lower than other studies in bovine, like Belina and Melese (2017) study result showed fasciolosis and hydatidosis alone contributed 690(35.1\%) gross pathological lesions.\par
Previous studies have indicated a higher economic loss resulting from a condemnation of edible organs and carcasses due to parasitic causes  {\ref (Negategizeet al., 1993;} {\ref Jembere, 2002;}\hyperref[b31]{Jibat, 2006)}. In the current study, these parasitic causes of liver lesion might be due to improper wasting of condemned organ and the stray dog feed it at abattoir and selling of infected offal for dog which is final host for teniculosis and hydatidosis and stay them. Sissayet al., (2008) studied the prevalence and seasonal incidence of cestodeparasite infections of sheep in Eastern Ethiopia for two years  {\ref (2003)} {\ref (2004)} {\ref (2005)}. Duringthis period, viscera including liver, lungs, heart, kidneys and the gastrointestinal tract were collected from 655 sheep slaughtered at four abattoirs. One of the most prevalent metacestodes was C. teniculosis. In sheep, the overall prevalence was 79\% for C. teniculosis.\par
The causes for calcification abscess, hepatitis, cirrhosis and discoloration were difficult to identify grosslyand it may be due to systemic infectious diseases. Calcification is also another lesion that we encountered; it can be caused by injury, infection, and autoimmune disorders. Large-scale tissue damage is associated with extensive loss of cells, a situation referred to as tissue necrosis. The death of tissue in a specific area of the body leads to the release of signaling factors that attracts cells to clean up and heals the dead tissue. This process, known as an inflammatory response, attracts calcium into the damaged area as it heals \hyperref[b9]{(Carne, 2010)}.This study indicates 24(12.5\%), 9(4.7\%) and 3(1.6\%) of Liver, lung, and kidney, respectively were affected by calcification.\par
Abscess was also a pathological condition; which is a collection of pus circumscribed by fibrous tissues. It occurs with great frequency throughout many organs and the carcasses of the meat animals and may be associated with a general condition or be found as isolated lesions \hyperref[b36]{(Libby, 1975)}. In present study 13(6.8\%), 6(3.1\%), 6(3.1\%), 2(1\%) and 2(1\%) of liver, GIT, kidney, heart and carcass were affected by abscess. In agreement with (FSIS, 2009) stated that caseous lymphadenitis is a disease of sheep and goats caused by the C.Pseudotuberculosis. Postmortem findings may include, enlarged abscessed lymph nodes with greenish white-yellow caseous exudate, which tends to become dry and granular, cross-sections of lesions contain remnants of connective tissue capsules (resembles the concentric rings seen on the cut surface of an onion). Lesions found in many lymph nodes, especially the subiliac, superficial cervical, deep popliteal, tracheobronchial, and mediastinal lymph nodes, as well as lungs, heart, liver, spleen, and kidneys. \hyperref[b5]{(Asrat, 2004}) stated that occasionally the worms penetrate the bile duct wall into the liver parenchyma causing liver abscesses.\par
The study conducted in Gondar abattoir (Meseleet al., 2012) and Nekemte \hyperref[b41]{(Moje et al., 2014)} also revealed that livers and lungs are the most rejected organs by PM inspection and fasciolosis and hydatidosis are the major causes of rejections. However, in the current study different calcifications, cirrhosis, hepatitis, abscessations, emphysema, pneumonic lesions, marbling (contagious caprine pleuropneumonia (CCPP)) lesion, nephritis, foreign body, traumatic lesions and others nonparasitic abnormalities and unidentified lesion contributed to a condemnation of organs and carcasses were investigated.\par
Lungs were condemned because of C. teniculosis, hydatid cysts, marbling, emphysema, calcification-,pneumonia, other unknown caused lesion and abscess which were (35.7\%), (21.4\%), (17.8\%),(16\%), (16\%), (12.5\%), (5\%) and (3.6\%) respectively. C. teniculosis accounts for 35.7\% as a principal cause of lung condemnation in sheep this might because of increased number of a stray dog in the area, the principal cause of lung condemnation was parasitic. However, the report observed during a retrospective study  {\ref (Reassert al., 2013)} reported pneumonia as a principal cause of lung condemnation in central Ethiopia accounting for 42.1\% (Get chew, 2008).In current study, from the total lungs inspected higher 56 (29.2\%) lungs were condemned. It may because of the animals unable to resist stress within a short period of time during transportation along way on foot, shortage of feed and water, stress due to hitting of animal by personnel who driving animal to market from the farmer and to abattoir and does not getting sufficient amount of rest at lair age may causes this respiratory problem.\par
FSIS  {\ref (2009)} reported that pneumonia is an inflammatory condition of the lungs that maybe caused by infectious agents, parasites, physical trauma, or foreign material in halation. In similar reports pneumonia might also be as a result of endemic diseases of sheep and goats such as pasteurellos are which is triggered by stress, contagious caprinepleuropneumonia \hyperref[b47]{(Radiostitis al., 2007)}. The other cause was marbled appearance (CCPP) lesions: CCPP is a disease peculiar to shoat and takes the form of a chronic inflammation of the lungs and pleura. It is not communicable to man and the carcass and the lungs found to be positive for CCPP can be passed for human consumption after a partial condemnation of the diseased part \hyperref[b24]{Gracey and Collins (1992)}.On the other hand, Emphysema is an abnormal and permanent enlargement of air spaces distal to terminal bronchioles with destruction of their alveolar walls, whereas oedema is a nonspecific lesion in which interstitium and alveoli are accumulated with fluid \hyperref[b9]{(Carne, 2010)}.\par
Also, different lesions of infectious and noninfectious causes like abscess, pericarditis, nephritis, and discoloration were found to be important causes for the condemnation of edible organs like liver,  \hyperref[b45]{(Ojo, 1992)}.\par
In the present study, out of the 11 (5.7\%) kidneys condemned abscess 6 (54.5\%) account, whereas calcification accounts 3(27.2\%), nephritis 2(18.2\%) and other unidentified causes 2(18.2\%) (Table \hyperref[tab_3]{3}).In this study abscess was a principal cause of kidney condemnation, however, the result in (Dejeneet al., 2013) study revealed out of the 57 (6.71\%) kidneys condemned Nephritis 20 (2.35\%) accounting for 11 (2.59\%) and 9 (2.12\%) kidneys in Ovine and Caprine respectively, was the principal cause of condemnation. Radostitiset al.,  {\ref (2000)} stated that embolic nephritis occurs after septicemia or bacteremia when bacteria lodge in renal tissue.\par
The major causes of heart condemnation were found to be pericarditis, hydatid cyst and abscess. Out of the total of 11 (5.7\%) hearts condemned due to gross abnormalities, pericarditis contributes about 4 (36.4\%) and hydatid cyst also contribute 4(36.4\%) and abscess 3(27.3\%) out of condemned organs Table \hyperref[tab_3]{3}.The main cause of lesion in GIT condemnation primarily parasitic C.teniculosis and abscess 6(46.2\%) and foreign body 4(30.8\%). As a septic lesion, whenever localized abscess is found, partial condemnation is recommended \hyperref[b24]{Gracey and Collins (1992)}.\par
The main management practices that rendered organs and carcasses unfit for human consumption were bruising of the carcass mainly brought about by not proper handling of animals during transportation to the slaughterhouses by hitting the animal with thick stick and mechanical damage to organs due to faulty evisceration especially liver. Apart from affecting carcass value, bruising has also animal welfare implications as excessive use of sticks while driving to the abattoir, mishandling of animals during loading and unloading, improper transport vehicle and at slaughter could be responsible causes  {\ref (Mungubeet al., 2006)}. It is stated that bruising of animals during transport is the major source of economic loss in Africa and Asia \hyperref[b40]{(Mitchell and slough, 1980}). In the present study out of 7 carcass condemnations, 2 (28.6\%) whole carcass was also totally condemned due to the yellowish discoloration, suspecting liver disease which may toxicity, systemic disease causing prehepatic and hepatic jaundice. Herendaet al.  {\ref (2000)}stated that icterus is the result of an abnormal accumulation of bile pigment, bilirubin, or of hemoglobin in the blood. Jaundice is divided into three main categories. Prehepatic jaundice occurs following an excessive destruction of red blood cells. Tick-borne diseases such as Babesiaovis and Anaplasmosis cause this type of icterus. Hepatic jaundice occurs due to direct damage to liver cells as seen in liver cirrhosis, systemic infections, and in chemical and plant poisoning. In sheep, jaundice may have been caused by phytogenic chronic copper poisoning. Obstructive jaundice occurs when the drainage of the bile pigment bilirubin is blocked from entry into the intestine.\par
However, parasitic C. teniculosis and Stelezia hepatic have no public health importance; they are considered as the important cause of economic loss in the meat industry since viscera harboring them are rejected for aesthetic reasons. The threat these parasites pose to small ruminants' meat industry in Ethiopia is evident due to the present situation of improper disposal of offal at abattoirs and backyard slaughter. The presence of freely roaming stray dogs on grazing land together with livestock and the deeplyrooted habit of feeding dogs with offal, including sheep heads, are important risk factors. This may lead to the perpetuation of the life cycle between intermediate hosts (sheep) and the final hosts (dogs) for C. teniculosis and hydatidosis.\par
The financial loss in the abattoir was high, in this study analyzed those losses through condemnation of organs and carcass from local market. A total loss of(56,576 USD USD)was incurred in the abattoir. Carcass condemnation accounts highest part of the losses of the total direct losses whereas liver, lung, GIT, heart and kidney takes, respectively.\par
The indirect losses from body weight gain, mortality at the farms, public health implications (cause of treatment for a human when diseased upon eating of the affected edible organ which is zoonotic) were not included in the analysis in this study. Thus, the total financial loss attributable to diseases of ovine and, hence, abattoir wastage could be much higher. The economic analysis of livestock diseases in Ethiopia is scarce and inadequate because of lack of information on the prevalence and partly by the complexity of the analysis. Negategizeet al.  {\ref (1993)} have reported a financial loss associated with a liver condemnation due to ovine fasciolosis alone in the central highlands of Ethiopia amounting to be 2.3 million Ethiopian Birr (460, 000 USD). Similarly Jobreet al.  {\ref (1996)} have estimated a total annual loss of 1.3 million Ethiopian Birr (260 000 USD) resulting from offal condemnation and carcass weight loss 
\section[{V. Conclusion and Recommendations}]{V. Conclusion and Recommendations}\par
The current study revealed that, during the study period different signs of diseases, and abnormalities leading to conditional approval, rejection and detain of animals were encountered at AM inspection. In lesion survey, a total of 192 gross pathological lesions resulting in partial and total condemnations of liver, lung, kidney, heart, GIT and carcass were investigated.  {\ref Different}  \begin{figure}[htbp]
