Survey on Pathological Lesion and Its Financial Losses in Ovine Slaughtered at Jimma Municipal Abattoir, Jimma, Ethiopia by Dinaol Belina in CDVS in Lupine Publishers
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 recorded as the major AM
findings of the current study. Accordingly, 47 (12.2%) sheep showed
signs of diseases and abnormalities; of which 23(6%) were conditionally
approved whereas 11 (2.9%) sheep were unfit and judged to be detained
and rejected. In the present study age, body conditions and geographic
origin of the animals were considered as study variables, and the
results showed BCS and age groups had statistically higher (p ≤ 0.05)
rejection probabilities. PM examination findings indicated a total of
192 lesions were encountered, of which 48.9%, 29.2%, 6.8%, and 5.7%
lesions were recorded from livers, lungs, GIT, and hearts and kidneys,
respectively. During the PM inspection, both total and partial
condemnation judgments were passed on organs and carcass appeared with a
sign of abnormality. C. teniculosis 58 (30.2%), calcification
36(18.7%), abscess 31(16.2%), hydatid cyst 23 (12%), hepatitis 10
(5.2%), pericarditis 4(2%), bruise 3(1.6%) and nephritis 2(1%) were
found to be the major pathological lesions recorded. In two sheep all
organs and carcass were totally condemned as their entire bodies
appeared yellowish. The direct loss due to the condemnation of organs
and carcasses at Jimma municipal abattoir was also investigated in
slaughtered sheep, and there were about 56,576 USD losses per year. In
conclusion, this study has identified the pathological lesions affecting
edible organs and meat, and then rendering them unfit for human
consumption. The study also estimated pathological lesions associated
direct financial losses at Jimma abattoir. Therefore, further studies
focusing on the primary causes of the abnormalities were recommended in
the study area.
