Abstract

It is fundamental the knowledge about predominance of hepatic lesions, to monitor them and
supply material to the preventive veterinary medicine actions, thus improving the production
process, reducing economic losses. In this work were catalogued morphological alterations in
livers of slaughtered bovines from an abattoir under Federal Inspection Service in Presidente
Prudente, São Paulo State, during the period of April 01 2010 to March 31 2011. The lesions
were catalogued according categories: degenerative, vascular, inflammatory, extra hepatic,
parasitary and neoplasic. To classify the alterations, was considered fundamentally
characteristics like color, texture and hepatic parenchyma consistency. Were inspected 100,723
animals, which 72,638 (72,12%) males and 28,085 (27,88%) females. 5,204 (5,17%) from total
showed some kind of hepatic alteration. Most significant alterations group was inflammatory,
including hepatitis, perihepatitis and supppurative lesions (34,69%). Second most
representative group was vascular alterations like telangiectasis, capsular hemorrhagies and
passive congestion (31,80%). Liver condemnation by extra-hepatic causes is high, mainly
associated to organ secondary contamination. The fasciolosis was observed in 29 parts of liver
(0.56%), suggesting that this parasitosis is adapted to the region, drawing attention to its
zoonotic potential and to being an emerging parasitosis.
